Tarsi longer than the middle toe, smooth ; feet naked ; inner toe free, hardly longer than the hind one; lateral toes equal. Wings short, rounded; spurious feather very short; second and third primaries longest. Tail short. Female hardly differing in plumage from the male : young more tinged with reddish. Moults annually. Plumage imperme- able (water-proof.) Solitary. Lives near brooks and clear rivulets, diving and walk- ing on the gravel bottom, often entirely under the water, which appears to be its favourite element. Feeds on aquatic insects, especially small Crustacea. Builds in the vicinity of rivulets, hiding its nest carefully. Flight rapid, straight, skimming the surface of the water. Voice feeble, shrill. Inhabits the north of both continents. Composed of but two intimately allied species, both probably Asiatic, though one is found in Europe and the other in North America. Remotely allied to the order Grallce by its habits, (which are still more aquatic than those of true water-birds,) and by the nakedness that prevails around the head ; but belonging decidedly to this family (Canori) where it is related especially to TurduSy Myio- thera^ Saxicola^ &c.

Inhabits near the Rocky mountains, on the Athapescow Lake, probably north-eastern Asia. Obs. This species (which we do not hesitate in referring to Temminck's Cinclus Pallasii^ notwithstanding its conjectured locality, which at first led us^to consider it as new, under the name of Cinclus ufiicolor), is the more interesting, in as much as the European species was the only one well known of the genus, which I noted, in roy '' Observations on the Nomenclature of to the Genera of North American Birds, 63 Wilson's Ornithology," as one of the twenty-five European genera not found in America.* GENUS LXXVIII. bis. PHALERIS.+ N. B. In my analytical table of North American genera, this genus must take place under the three-toed section of the family of Pi/gopodes, between the genera Una and Mormon^ and be thus characterized : 78. bis. Phaleuis. Bill curved, compressed, longer than high ; nostrils half closed by a naked membrane, pervious. Alca, L. Gm, Lath. 111. Cuv. VieiU. Phaleris, Temm. Sp. 359. bis. J Phaleris cerouhynca. Nob. Blackish; belly whitish ; a few slender, elongated white feathers from the corners of the eye and mouth ; bill smooth, surmounted at the base by a long obtuse horny process. Inhabits the Western coasts of North America. Obs. This new species, the third well known of the genus, from the remarkable anomaly of its bill may hereafter be con- sidered by some Ornithologists as the type of a new genus, or at least a subgenus. Hence we have been induced to apply to it a specific name, which being compounded from the Greek might, with propriety, become generic. I shall take this opportunity of noticing that in a collection of birds from Havanna, sent to Mr. Vigors by Mr. MacLeay, I have had the pleasure of finding a beautiful specimen, apparently a male, of the new species of Dove, which I lately established under the name of Columba Zenaida^ from a single female specimen from the Florida Keys. The range of the species thus appears to be not so limited as might have been supposed. * The two species of the genus may thus be eharacterized in the General System of Ornithology. 1. Cinclus aquaticus , Bechst. (bicolor Vieill.) Cinereo-brunneus, pectore albo. Habitat in Europa et AsiS, Boreali. 2. Cinclus Pallasii, Temm. [unicolor? nob.) Fusco-cinereus, pectore concolore. Habitat in America, {an quoqucy Asia ?) Boreali. + By the additions of three genera (Cinclus^ Aramus, Phaleris,) our North American genera are carried to eighty-three, which, instead of eighty, ought to be the number of Alca.

Geoffuoy Saint-Hilaire and Frederic Cuvi^r, have given in their superb work, L'Histoire Naturelle des Mammifires^ Li-craison XII. a description and plate of a Dog, under the deno- mination of Chien des Esquimaux de la Bate de Baj[p.n^ the mother of which they inform us, was obtained through the kindness of Dr, Leach. " Nous devous ces precieux animaux a M. le Docteur Leach, qui, en ayant obtenu une femelle pleine, au retour de I'expedition du Capitaine Ross, a bien voulu nous I'envoyer. Cette femelle a mis bas trois petits, un male et deux femelles, qui suffi- ront sans doute pour nous conserver une race dont I'intelligence et la force, appliquees a nos besoins domestiques, pourront nous reudre d'utiles services. Aucune de nos races de Chiens, qui se rapporte a celle-ci, ne sont aussi belles et aussi fortes." The figure is that of the young male whelped at Paris. The learned authors of the Mammiferesj evidently consider this animal as representing the genuine Esquimaux Dog ; but it ap- pears from Captain Sabine's remarks in his Supplement to the Appendix of Captain Parry's Voyage in 1819 — 20, that the pup- pies which were born at Paris, were the spurious issue of a male Newfoundland Dog and the female of the true Esquimaux race, presented to the French naturalists by Dr. Leach. " By an omission, doubtless of inadvertency, the keepers of the menagerie ■were not apprised that the female in question was with young by a Newfoundland Dog belonging to an officer of the Isabella ; and it has unfortunately happened, that the plate of the ' Chien des Esquimaux de la Bale de Baffin,' as well as the minute measure- ments and description in the letter-press, are taken, not from the mother, but from one of the young, after it had attained its full growth; and it is not therefore a representation of a genuine Esquimaux Dog, as the authors designed." App. Mammalia^ Art 4. Ca7iis Lupus, p. 186. Under these circumstances we have gladly embraced the op- 4 irt MUsi Mr. Children on the Esquimaux Dog. 55 portunity afforded us by the kindness of Lieut. Elliot Morris, R.N. of giving an accurate figure (Plate I.) of an unquestionably genu- ine male Esquimaux Dog, brought from the Polar sea by Mr, Richards, in Captain Parry's first Voyage, and by him presented to his friend Mr. Morris, in whose possession the dog still remains. The dimensions of Akshelli (so the Esquimaux had named this animal) are as follows — Length from the occiput to the insertion of the tail . 28 Inches, from the occiput to the extremity of the nose 1 1 tail (about) 18 ears 3 from the eyes to the point of the nose ...... 4 Breadth between the ears 4| Height from the ground to the top of the shoulder .... 24 The ears are erect and pointed, the tail very full, and thickly covered with very long hair, and curled, towards the right hand over the back. The legs are very stout. The hair on the body and legs is rather long, very thick, soft, and somewhat woolly — its colour above is nearly black — the forehead is black, with a white streak down the centre, from the top of the head nearly to the extremity of the nose — over each eye is a white spot — the lower part of the face, the chin, belly, legs, and feet are white. The tail is blackish above, from its insertion to about five inches from the tip, which with the whole of the under side is white. Such are the colours and markings of the Dog before us, but like those of most other domesticated animals, they are of course very liable to considerable differences in different individuals. Akshelli is good humoured, but rather impatient of restraint, and seems particularly to dislike being examined about the head, snapping at my hands somewhat angrily, on my applying the rule to measure its length. He seldom barksj but if displeased utters a low wolfish growl. He takes very little notice of strangers, and is of no use whatever as a guard. He feeds on carrion, and prefers raw flesh to such as has been cooked. The strength of this dog is very great ; when taken from his kennel, he appears extremely anxious to get at liberty, and when held back by his chain and collar, exerts himself with great powerj increasing his 56 Mr. Westwood on Siagonium quadricorne^ 8fc, efforts in proportion to the resistance that restrains him. A stout Boy of fourteen, servant to Mr. Morris, was unable, when the dog exerted his utmost strength, to hold him back ; the animal dragged him forward several paces, in spite of all his efforts to prevent it. J. G. C. Art. IV. Observations upon Siagonium quadricorne of Kirhi/^ and on other portions of the Brachelytra (Staphy- linus, Lin.) By Mr. J. O. Westwood. [To the Conductors of the Zoological Journal]. Gentlemen, If the following observations on the above singular and (till lately) extremely rare Insect, and on other Insects belonging to the Linnean genus Staphylinus^ should be thought worthy of in- sertion in the Zoological Journal, by permitting them to occupy a place in its pages, you will oblige.

In the course of the last autumn, I had the good fortune to cap- ture this insect in large quantities, under the bark of felled and de- * There is a sufficient difference between the names Siagonium and Siagona (a genus of Carabidse), without incumbering our Nomenclature with another generic name for these insects. Larva of Siagonium quadricorne. 57 caying trees in Kensington Gardens ; but by far the greater portion of them were females, their number exceeding that of the males, in the proportion of, at least, five to one. These last, although differing much in size, were, (contrary to the rule commonly observable in injects) all larger than the females ; this however is well ascer- tained to be usually the case with the generality of insects whose males have the head or other parts of the body, furnished with horns — but amongst the specimens of that sex there were very few in which the horns of the head were fully developed ; but where this was the case, these perfect specimens (if I may be allowed to apply thjs term to insects already in their perfect state), were much larger than the others — (See Note 2.) The colour of the thorax and elytra of the females varied from bright chesnut almost to blaek. On loosening a portion of the decayed bark, it is surprising to pbserve the facility and quickness with which these minute crea- tures again shroud themselves under that which remains, but which still firmly adheres to the trunk, and this is rendered still more curious when the slowness of the insect's motions is atten- tively observed ; it is however easily accounted for, when we no- tice the extreme flatness of the body and the strength of the legs. I have been informed by several gentlemen who took them in Kensington Gardens in the course of last year, that (like many of the Staphylinidce) they may be found throughout the season. H. Griesbach, Esq. also informs us, that he found them in profu- sion in similar situations in Windsor Park, during the summer, and I believe Mr. Denny took them in JNorfolk about the same time. I have also since met with them in Lord Spencer's Park, near Wimbledon, Surrey. It may not be unworthy to remark, that wherever I have dis- covered the perfect insects I have also found a quantity of small larvae, and which I have little doubt are the young of the SiagO' niumy in which opinion I am confirmed by a remark of Latreille (Regne An. iii. 218), who says, " Ces larves se nourissent des memes matieres que I'insecte dans son dernier etat." They do not, however, exactly agree with the characters of the Staphylini- dous larva, as described by this author in the work quoted, and 58 Mr. Westwood on Siagonium quadricorne, SfC. therefore I do not hesitate from the attention at length bestowed on the larvae of Coleoptera, to subjoin a description of one of them.

This description of the Larva of Siagonium may serve as the type of MacLeay's family Omalidce ; and in order to show the differ- ences existing between the Larvae of this and another of his families, I here subjoin a description of one which I had con- ceived to be the young of Goerius olens^ but which Mr. Kirby recognized as belonging rather to Philonthus politus^ or one of its affinities, and which will serve as the type of the larvae of the family Staphylinidce^ as restricted by Mr. MacLeay in the Annu- losa Javanica.

Habitat in Stercore, tempore vernali. Gravenhorst (Coleopt. Micropt. Pref. Ixi) after stating the difficulty of attending to the manners, &c. of these Larvae at different periods of their life, observes that he has occasionally- found the solitary black Larvae " Speciei cujusdam majoris Sta- phylinorum (S. Olentis? S. similis?) in sylvis locis enebrosis suffocatis, sub muscis arborum caesarum," and which from his des- cription differs but slightly from that described above. The first segment of the body he observes, '' thdraci insecti perfecti res- pondebatj" and the 2d and 3rd " pectori insecti perfecti respon- debant." He describes the last joint of the abdomen as being " subpenultimum retractum anum emittebat cylindricum, longitu- dine segmenti, co autem quadruplo angustiorem et supra spinis 60 Mr. Westwood on Siagonium quadricorne^ 8fc. duabus segmento loiigioribus, tripartitis quoad formam cornua cervina aequautibus armatum." It is somewhat remarkable that DeGeer has figured no Staphj- linidous larvae, nor am I aware of any author who has done so. I also add a description and figure of a third Larva, which for the reasons after mentioned, I had conceived to be that of Aleo- chara fuscipes ; but the receipt of the following communication from Mr. Kirby has considerably shaken such opinion — " I sus- pect," he says, " that the Larva fig. 3, is not the Larva of any of the Brachelytra — From its habitat it may belong to one of the Niiidulidce^ which are very common in bones, (Comp. Introd. to Eot. iii. 168) — My Larvae of that form are too large to belong to an Aleochara^ and I find them in carcases, with Silphidce of the larger kinds." Larva Fig. 3. A. aucta. E.

Habitat in ossibus siccis tempore oestivo. I shall now state my reasons for having considered these last as the Larvaj of Aleochar a fuscipes. They were Ist, from finding them together with the Aleocharce^ and also the cast-ofF exuviae of the pupae in the same dry rotten bone, the Larvas running about as quickly as the perfect insects, and apparently of the full size, and the exuviae partly sticking out of the different small crevices in the bone, and not larger than the Larvae ; no other insect pre- senting itself except a small Hister : and 2"*'^ from their perfectly agreeing (except in their ovate form, and a few other minor differences) with the general characters of the other Larvae above described, and more particularly in the essential structure of the the description of Latreille of the Larvae of the NitidulidcB^ in the antennae and anal appendages, which latter entirely disagree with Hist. Nat. &c. quoted below, and it is also confirmatory of my Situation of Siagonium in the Brachelt/tra, 61 opinion that the species of Jleochara generally present a far more dilated appearance than many other species of Brachelyira. De Geer (v. iv. pi. 6. f. 11) has figured the Larva of Silpha obscura, and which exactly agrees with Latreille's description of the Larvae of that genus in the Hist. Nat. &c. and which he says has twelve segnnients,and is "alonge, tres aplati," and also " termine sur les cotes en angle aigu " — the anal appendages are described as " deux petites appendices coniques " — and not as being jointed as in my Larvae. DeGeer's figure exhibits the antenna? much lon- ger than in the Larvae last above described by me, and it would seem from the figure of the upper and under side of the anterior segments of the body, that the head is entirely immerged in the underside of the first segment of the trunk, and which will account for Latreille calling it 12-jointed. Latreille, in the work last referred to, describes the Larvae of the genus Nitidula, as nearly resembling those of Silpha. Body flat and long with twelve joints ; " termines lateralement en uti angle assez aigu." The last joint, as in Silpha being " garni de deux petites appendices coniques" — If however Mr. Kirby's opinion should hereafter be confirmed, there can I think be no greater proof of the connexion of the Necrophaga and the Brache- li/ira than the strong affinity of these Larvae. I ought not to omit to mention (since the resemblance existing between the forms of Larvae and other groups of Annulosa has become an interesting subject of investigation ; (consult K. & S. Int. 3. 162) that the dilated appearance of the Larvae last above described by me, bears a most striking analogical resemblance to the shape of the body of Philoscia muscorum^ one of the Onis^ cidce. The situation of the sub-genus Siagonium in an arrangement of the BrachelytrUy will be between Bledius * and Zirophorus^ a • I am indebted to my friend Mr. Stephens for a sight of a new species of this interesting genus, lately taken on the Coast of Norfolk, by Mr. Skrim- shire, and which may be thus characterized — Bl. Siephensii. Fig. 4. A. B. Magnitudo, statura et summa affinitas Bl. armati—Dl ffert praecipue, capite masculo cornubus duobus, elongatis, lateralibus, acuminatis, erectis armato, (B.B.

(Leptocherius of Germar is synonymous with this genus). To the MacLeayian entomologist I should conceive that no group can supply a fitter subject for study than the Brachelytra^ and for the following reasons : 1st, it is rarely that an exotic insect of this group is seen in any of the cabinets.* Jurine has observed on a somewhat similar occasion, '' Je ferai remarquer ici qu'il est bien etonnant de ne pas trouver davantage de tenthre- des exotiques, decrites dans I'ouvrage de M. Fabricius, lui qui a visite un si grand nombre de collections ; Ou serait presque en droit de demander a quoi tient cette rarete, si I'on ne connaissant pas le peu d'empressement qu'on a eu jusqu' a present pour col- lecter les Hymenopteres et les Dipteres."f — This however cannot be said with regard to the Brachelytra^ for Mr. MacLeay, (Ann. Jav.) tells us " That it is a singular circumstance that no insect of the Stirps was collected by Dr. Horsfield. This at all events proves the extreme rarity of such insects in Java. Of their ex- istence in the Island I have however no doubt : when it is con- sidered that the British species are so numerous, it appears very structo; duabus lateralibus brevibus medioque elongate, acuminate, apice piloso, et supra caput inter ejus cornua, erecta, procumbens (AA). Fagmina multo minor et absque cornubus est. Fig. 4. C. Thorax Bl. armati. Domino J. F. Stephens viro amicissimoj et in Insectis Brittaniae certe peri- tissimo, hoc insectum singulare inscripsi. De Jean, in his catalogue, has named a species from Dalmatia, Oxytelus Taurus, but as there is no description annexed to the name, it is impossible to be- certain of the identity of the species ; nor do I consider that vye are in the slightest manner bound to notice any name given in print where no suffi- cient description is added. Note — Oxytelus fracticornis and its congeners, ought to form a distinct Sub-genus. They are much nearer allied to Bledius than to Oxytelus. * Out of the 434 Brachelytra mentioned in De Jean's catalogue, only 12 are extra Europaean ; and Messrs. Kirby and Spence (vol. iv. p. 489) state, that from the present catalogues, the metropolis of the Brachelytra appears to be in Britain; Mr. Stephens possessing upwards of 600 British species. + Nouv. Meth. de classer les Hymen, p. 63. Constitution of the family Omalidaz. 63 extraordinary that not one should have occurred in Java." And even when an exotic species is found, it does not present so great a difference of form from the European species as is observable in most of the other groups. The second, and by far the more im- portant reason, is the amazing variety of forms presented to us in the known species, and which when properly investigated, would doubtless be highly useful in pointing out the proper places of other corresponding analogous groups ; as in the case referred to by Mr. MacLeay, in the Annulosa Javanica, of the genus Oxypo- rus possessing similar labial palpi with the genus Engis, I have little doubt as to the family Omalidce being a perfectly natural one, consisting of the different genera which Latreille has placed in it, with the exception of Aleochara ; on which I shall now offer a few remarks. I have before stated that I conceive this genus not in its proper position, where Latreille (Cuv. Regne An. 3. 223, and Latreille, Fam. Naturelles, 245) has placed it ; namely, in his division Appldtis ; (Omalidce, MacLeay) and the grounds of this opinion rest, not only on the very different exter- nal appearance which these insects present, but more particu- larly on the 4th joint of the maxillary palpi, (on which Latreille has principally founded his four divisions) and wJiich does not well agree as to size with the description of the same part in the characters of his division Applatis. He says in his description of the last, " les palpes maxillaires avec le quatrieme article dis- tinct;" but describing the same part in the genu^ Aleochara, he says, " le dernier article tres petit " — and in fact, by placing this article at the end of the division, he appears to have been aware of their connexion with the next. In his '' Gen. Crust. & Ins." he has arranged the genera differently, and has placed those of Tachinus, Tachyporus, and Aleochara together, at the end of the Brachelytra, and which appears to me far more natural. I shall only add, that long before I had seen either of the above arrangements by Latreille, I had grouped these three genera to- gether, and had styled them " Aleocharides,^^ and I observe that Messrs. Kirby & Spence, have also made use of the term " Aleo' charidw^^ to designate the same insects. Placing then, the Akocharce with the Tachini & Tachypori^ I 64 Mr. Westwood on Siagonium quadricorne, Sec. would divide the family Omatkice into two sections — the first com- posed of the genera Omalium^ Froteinus^ Jfithopagus, Eloniurn^'^ &c. and the second comprising Oxytelus^ BlediuSj Evcesihetus^ &c, and then the connexion between the genera appears strikingly natural : Eloniiim^ combining in itself the external appearance of an Oxytelus^ and the maxillary palpi oiOmalium (to which genus it bears great affini(y,and of which, the type El. striatulum was a spe- cies, both with Gravenhorst and Gyllenhall), joining the two sec- tions at one point, where the insects of both sections are of an elon- gate form, and the interesting genus Evcesthetus (in external ap- pearance resembling the depressed Ojjiatia^ and more particularly Om, refusum (which will form a new subg'enus) and which until separated by Gravenhorst, was placed in the genus Oocyielus and which De Jean has also placed between Oxyttlus and Oma~ Hum ;) serving to connect the two sections at the other point, * Staphylinus striatiilus, Fab. (Om. rugosum, Gr. Gyll.) has been formed into the genus Elonium by Dr. Leach— but I believe no characters have yet been published of it. Plate II Fig. 6 represents the Maxilla of this Insect. Fig. 5 ditto of the genus Omalium. (the type of which I consider to be Omal. rivulare) Fig. 7 ditto of Oxytelus carinatus, (Staph, rugosus Marsh.) which I consider as the type of that genus. Fig. 8 ditto of Siagonium quadricorne. Fig. 9 ditto of Zirophorus fronticornis. And it is not a little singular that tliese two last Insects, which, from their ap- parent aflBnity with Oxytelus, we miglit infer would possess maxillary palpi similar to those of that genus, present these organs nearly agreeing in form with those which Omalium possesses. Indeed from my own observations on the subject, I have little hesitation in saying, that the maxillary palpi alone do not present characters sufficiently precise to enable us to found our divisions upon them, and I am confirmed in my opinion by Mr. MacLeay's remarks, both in his Horoe Ent. Part. 1. and also in his Annulosa Javanica, and more particularly in his observations in the last mentioned work on Latreille's Section of Carabidae " Subulipalpes" (Bembidium) which was established on the same organ : and Mr. Kirby likewise in his Century of New Insects, (Lin. Trans. Vol. 12), speaking of the comparative length of the maxillary and labial palpi upon which the genus Megacephala is built, gives it as his opinion that it merely indicated the section of a genus, rather than a Genus. Groups of the Bracheli/tra. 65 and at which the insects of both groups are of a dilated form : and thus to complete tlie circle.* Whether the four remaining F&mWies^ xiz.Staphi/lmidceySienidce, TachyporidcB^ and Pselaphidce^he perfectly natural ones, I am not prepared to say ; they however certainly appear to me to be so, and I shall here only endeavour to shew the points of connexion between some of the groups. Gyllenhall, (Ins. Suec. 2. 372) speaking of the genus PcederuSy which belongs to the Stenidce^ (Longipalpesy Lat.) says " In ipso apice articuli tertii palporum anticorum, interdum acumen minutum observatur, quod forte praesentiam articuli quarti licet retracti den/>tat ; quare hac in re, generi praecedenti (Lathrobium.) nimis affines sunt Pwderi" — And Lathrobium is placed by La- treiile in his Section Fissilabres (Staphylinidce^ MacL.) — As to the PselaphidcE, Latreille, (Regne Anim. 3. 364) says, they have " une grande affinite avec les Aleochares." — The connexion between the Brachelijtra (the last and certainly the most aberrant Stirps of the Chilopodomorphd) and the terres- trial Adephaga (the first and normal Stirps of the same tribe) evidently takes place, as Mr. MacLeay has observed, in the Ann. Jav. at the genus Lesteva (Anthophagus, Gyll.) and I shall add Gyllenhall's remark on this affinity : '' Generi Lebce quoad- modo similes et affines sunt hujus Generis (Anthophagi) Species; ideoque familiara praecedentem (Carabidce) cum praesenti (Brache- li/tra) conjungunt" (Ins. Suec. 2. 191.) I cannot quit the present subject without directing the atten- tion of British Entomologists, to a circumstance connected with the Bracheli/tra, which is mentioned in Dallman's work above re- ferred to, and which has I believe never yet been noticed in any English work (See Note 3). And as Dallman's work has not yet found its way into every one's hands, I am sure I need not apolo- logize for quoting the passage. * In the genus Elonium no sternmata are visible, and the consequent affinity to Oxytelus, which I regard as the type of the other section, is certainly very obvious — while on the other hand Eveesthetus does possess sternmata, thus clearly demonstrating its affinity to Omaliutn.

Since the greater portion of the above paper was written, the 3d & 4th Vol. of Kirby's & Spence's Introduction to Entomology, have at length been published. In the 4th Vol. p. 393, a plan of division of an order is given on a much enlarged scale. Whether too many divi- sions are not there introduced I do not pretend to say. I have not adopted them here from my ignorance of the corresponding groups in the Brachelytra. NOTE 2. It is not a little interesting to observe that these remarks concerning the developeraent of the horns in some specimens (written long before the publication of the two last volumes of Kirby & Spence) perfectly coin- cide with the observations in Vol. iv. p. 166 of that work respecting ano- Mr. G. B. Sowerby on Hinniles. €7 ther group {the Onthophagi) whose males are similarly cornuted. It will however require much attention and investigation to prove that the^ "perfect" specimens are (as suggested in the work referred to) of an intermediate sex, or a second sort of males, analogous to the Neuters amongst the gregarious Hymenoptera. After a re-examination of up- wards of 50 males, I have not been able to find intermediate specimens between those with the short boms and the few with these organs much enlarged. But may not this extraordinary developement be more ana- logous to the occasional (but much rarer) acquisition of wings and hemelytra in certain species of Heteropterous Hemiptera {Pyrrhocoris apterus for instance) generally found without such indication of per- fection ? NOTE 3. At page 506, Vol. iii of the same work, it is stated, *' that although Omaliura planum and its affinities, O. striatulum (Elonium Leach) and some others appear not to have Stemmata (Ocelli) yet with the aid of a good magnifier they may be discovered in most species of that genus, as likewise in Evaesthetus Grav." Also " that some species of Anthophagi appear to want them." As it does not appear that the authors have noticed Dallman's remarks on the subject, I have not thought it necessary to cancel the extract. Art. V. Observations on the Shells of an Acephalous Molluscum of the Family of Pectinidae, for which the Generic name of Hinnites has been proposed by M. Defrance; together with the characters of several Species, By G. B. Sowerby, F.L,S.^ S^'C. The history of this genus, if genus it may be called, may be summed up in a few words. Some years ago M. Defrance, ob- serving among some fossils sent to him by M. Cortesi, some speci- mens of an irregular bivalve, intermediate, as he considered it between Spondylus and Ostrea^ Lam., but not strictly referable to either, proposed for the two species in his possession the generic name of Hinnites^ under which article he soon afterwards published an account of them in the Diet, des Sciences Naturelles, la a short time, so many specimens of this singular genus were to E 2 68 Mr. G. B. Sowerby on HinnUes, be seen in the possession of collectors, particularly in Paris, that the naturalists of that metropolis had a fair opportunity of be- coming acquainted with its characters. Not so, however, the English collector, for the few specimens which found their way to this country were confined to one or two collections and were consequently scarcely known. The first notice that we find in connection with the genus in this country, has been given very lately in the Annals of Philosophy by Mr. Gray, who has de- scribed a recent species from a specimen in the British Museum. It cannot be considered as surprising that both M. Dcfrance, who proposed the genus, and Mr. Gray, who thus added to the informa- tion concerning it, should have mistaken its real relations, the first, who as we have before stated, ranked it between the Spoil' dylus and Ostrea^ having only some fossil valves ; and the latter who places it in the Spondylidce^ having described only a worn individual. It will be seen in the sequel of this communication that it rightly belongs to the Pectinidce^ and that it is hardly possible to separate it as a genus from Pecten^* but were it to be established as a genus, it must be placed in the Pecti?iidceA The examination of a number of specimens of three or four decidedly congeneric species have conducted me to the results which will be explained in the following observations. First, I must inform naturalists that one of our commonest British shells, a shell to which neither M, Defrance nor Mr. Gray has referred, belongs to this genus, namely Pecten Pusio of some, P. distortus^ of others. The singular manner in which this shell, almost con- * I am informed that Mr. Gray, immediately upon his return from Paris, has stated that he is convinced that Pecten distortus is of the same genus with Hinnites; as well as that the alteration from HinnUes to Hinnita is an error. f I cannot doubt the fact of the Pectinidos being all naturally affixed by a byssus, in the same manner as the Mytilidce; indeed I have seen so many proofs that I consider it as perfectly settled. It is no more difficult to account for the large number that we see, without their byssus, than it is to account for the immense quantities of muscles we see on some shores, also without their byssus. If indeed, it be asserted that we sometimes see the muscles thrown on the shore with their byssus, and that we never see the Pectines with theirs, we have only to suppose that the byssus of the Pectinidos is not so strongly affixed to the animal as that of the muscle ; we know, moreover, that it is much more slender. Mr. G. B. Sowerby on Hinnites. 69 stantly, becomes pressed close to, and takes the shape of the subf stances to which it adheres, and the extremely rare occurrence of an opportunity of observing its byssus, may have given rise to the idea of its being adherent by its outer surface to those substances; whereas the contrary is really the case, as is proved by the very young specimens which never have any appearance of adherent outer surface. The same circumstance also occurs in the shells called Hinnites by M. Defrance ; Mr. Gray's ignorance of it has undoubtedly been the cause of leading him to describe them as adherent by their outer surfaces and not by a byssus,* and con- sequently to the incorrect situation in the system, which both zoologists have assigned to them. I shall therefore next propose the following as an amended generic character, observing that it is only in the circumstance of its being apparently adherent by its outer surface, and not by a byssHS, that it diflfers from Pecten. Fam. Pectinid^. Gen. Hinnites. Defr.

J Testa oblong^, tenui, confertim radiato-striata, striis scabris ; auriculis inaequalibus, radiatim scabris ; valva inferiore subtus, 72 Mr. G. B. Sowerby on Hinnites, praBsertim margine basali, plerumque irregulariter depress^, polita. Shell oblong, thin, closely striated, striae radiating, scabrous ; ears unequal, with scabrous radiated strije ', outside of the lower valve, particularly the basal margin, generally flattened and smooth. The regularity of this shell in its young state is remarkable, particularly when contrasted with the irregular form it assumes as it increases in age ; and it is such as to render it, when young, a characteristic type of one of the divisions of the genus Pecten. This is a common shell on the coast of Britain ; it differs in the thinness of the shell and the distinctness of the ears from the other species; it is the smallest of all, seldom exceeding two inches ia height. The byssal groove is much more distinct than is usual in the other species ; in one specimen, however, of the H. Cortesyi which my brother possesses, this byssal groove is quite distinct. For about half an inch in height this shell is generally quite regular, afterwards it appears to be almost constantly pressed close to the substance to which it is affixed by its byssus, and some- times becomes fixed by the shell itself, by spreading the testa- ceous matter close to the surface and in undercut hollows. From the whole of the above I think it will appear that Mr. Gray had at first, though in error, come nearer to the truth in placing this genus among the Pectinidcey with Lima^ than after- wards in associating it with Spondylus and Plicatula ; it certainly is much more nearly related to Pecten than to either Spondylus or Ostrea. It will also be observed that Defrance has partly avoided an error into which Gray has stumbled, where he says of the genus that is '' adherente^'^ whereas Gray says " adherent by the apex of the right valve." Gray adds that it has " no byssal groove," which is also incorrect. Mr. Swainson's Memoir o/Lacepede. 73 Art. VI. Sketch of the Life and Character of the late Count de Lacepede, By William Swain son, Esq^, F.R.S., Sfc. [To the Conductors of the Zoological Journal.] Gentlemen, It has been too justly observed, that the records of our Science are remarkably deficient in the biography of those eminent natu- ralists who are now no more, but whose works we are continually in the habit of consulting. The lives of men who have trodden the " sequestered vale" of Science, do not indeed furnish the historian with those striking events, and splendid actions, which belong to the Hero or to the Statesman ; but they frequently teach us, that the wide circle of social duties maybe performed, and the mental powers exercised for the public good, without interfering with the philosophic speculations of the closet. The character of the late Count de Lacepede seems to have exemplified this, most fully. His name has been long and justly celebrated in every country where Science has spread ; and his funeral was honoured by three distinct orations, pronounced by M. le Comte Chaptal, M. Dumeril, and M. Geoffroy de St. Hilaire. From these public testimonials, the following short biographic sketch of this dis- tinguished and amiable man, has been compiled. As no similar notice, I believe, has yet appeared in our language, it may be in- teresting to many of your readers. I have the honour to be, &c. &c. William Swainson. M. le Corate de Lacepede (Bernard Germain Etienne) Mem- ber of the Royal Academy of Sciences, and Keeper of the Cabinets in the Garden of Plants, was born of a noble family, at Agen, la 1756. Naturally endowed with a passionate love of knowledge, he devoted the early period of his life to the study of natural philoso- phy, and the cultivation of music. On these subjects he published two volumes; and he has likewise been supposed to be the author 74 Mr. Swainson's Memoir o/"Lacepede. of two romances, and a volume of poetry.* At the age of twenty- one years, he went to Paris, and soon formed an acquaintance with BufFon. A congeniality of pursuits, strengthened by mutual re- gard, laid the foundation for a friendship between these two great men, which lasted during life. From this period, he became enthusiastic in the love of Natural History. M. de BuiFon soon appreciated the talents of his young friend, and free from those envious feelings, which, unfortunately, are found too frequently among the votaries of science, chose his most distinguished dis- ciple as his friend, his coadjutor, and appointed him the continu- ator of his works. In a few years he justified this choice by publishing '• I'Histoire Generale des Cetacees, des Quadrupedes ovipares et des Poissons." The elegance of the style of this work is worthy of its model. On the death of his distinguished friend, M. de Lacepede was chosen to succeed him, and the Garden of Plants henceforward became his adopted heritage. The fame he had now acquired, induced the Editors of the Histoire Naturelle, at a subsequent period, to request that he would undertake a new edition of the whole work, as a guarantee to the public for its excellence and correctness. At an early period he had principally directed his attention to Electricity, and to the Phaenomena of Natural Philosophy in general; but it was the great and laborious undertaking of continuing the Natural History of Buffon, that so greatly influenced the advancement of Zoology in his own country. It is in the department of Ichthyology that the labours of Lace- pede have been most conspicuous ; he reformed and amended the classification, and has given the characters and history of nume- rous genera and species unknown to his predecessors, including all those described in the manuscripts of the celebrated Philibert Commerson.+ The researches of the Philosopher, however, did not interfere with the more important duties of the Statesman.

After such an eulogium, it would reflect honour on the French Government, if his Manuscripts and Drawings were published under their auspices, and not suffered merely to remain deposited in the National Library. Mr. Swainson's Memoir q/'Lacepede. 75 inencement of those troubles which terminated in great horrors, M. de Lacep^de was called to the legislative assembly. Here his temper and moderation were eminently conspicuous; he long struggled to repress the first devolopements of those dreadful principles of anarchy, which soon spread through his devoted country, like a pestilential disease, corroding and destroying the root of all moral and religious feeling ; but the voice of reason or persuasion could no longer be heard or regarded in the popular frenzy: he withdrew until the storm was spent; and until he was again solicited to resume his duties at the Museum of Natural History. Some years afterwards, the reputation he had acquired again called him to the Senate, and subsequently he had the honour of being chosen Grand Chancellor of the Legion of Honour, and was created a Peer of France. In his political life M. de Lacepede was distinguished for his mildness, his moderation, and his love of justice. He laboured to establish order, to lessen the severity of certain arbitrary laws, and to render others more mild and supportable to the people; and such was the influence of his well-regulated mind, and of his reputation as a moral man, that his voice could moderate the angry discussions of that tumultuous assembly of legislators, over which he presided. He may be considered, as one of those very few, who after having fulfilled important and public functions, have not left an enemy to reproach their conduct, with a single act of tyranny or injustice. In Science as in politics, M. de Lacepede was remarkable for a love of truth, and a spirit of order and arrangement, which per- vaded all his habits. His works are characterized by purity of style, and by the enlarged views and conceptions of the philosopher. His leisure hours were devoted to the elegant amusements of the accomplished man. His love of music led him to acquire a knowledge of its principles, and his compositions, which have been previously attended to, in this and in other arts, shew the taste and cultivation of a mind naturally sensitive and alive to beauty. In private life he was affable, mild in his prejudices; and united great delicacy of feeling with a noble and exalted mind. It has been 76 Rev, R. T. Lowe vn Balanus punctatus, S^c. said that one of the most striking points in the character of M. de Lacepede, was a beihevolence which delighted to exercise itself for the happiness of others, — to relieve misfortune, and to mitigate suffering. In the midst of his honours, he preserved the early simplicity of his manners, and to his total forgetfulness of selfy may perhaps be attributed the fatal termination of that disease — the small pox — under which, at an advanced age, he expired, on like 8th of October 1825. His funeral took place at Epinay, and was attended by men eminent and illustrious in every branch of the Administration, who had sought and cultivated his friendship ; while crowds of villagers followed their benefactor with sorrow to the grave. No less than three orations were pronounced over his tomb, and from the closing passage of that by M. Dumeril, we shall conclude this imperfect sketch : — '' Profond observateur, ecrivain gracieux et brillant, savant na- turaliste, professeur eloquent, academicien celebre, genereux ami, homme excellent ; il faut done repeter ici Jans notre affliction, cet Adieu touchant avec lequel vous nous quittiez si amicaleraent, lorsque vous nous tendiez une main defaillante, et que le sourire gracieux, accoutume a obeir k votre ame aimante, cherchait en vain a se placer encore sur nos levres inanimees !

He has published this shell as a Mitra. The last plaits of the pillar, which are the largest, point out the r 2 i4 Mr. Broderip on some new and rare Shells, shell to be a Voluta, He has observed this to me, and as I believe that the observation has not been publicly made by him, I wish it io be understood that the correction is not mine but his own.

The ventral disc of the latter, though corrugated as strongly as that of C. rugosa at the extremities, is comparatively smooth in the middle, and there the rugosities scarcely appear, excepting towards the mouth of the shell, where they again be- come strongly marked. The rugosities of the ventral disc of C, rugosa furrow the whole of that disc, and are rather strongest in the middle of it. With this exception, the rugce on the disc, lip and margins of both shells offer the strongest similarity. The fossil appears much more gibbous than the recent shell above- mentioned. Art. IX. On the occurrence of some rare British Birds, jBy William Yarrell, E»q, F,L,S, [To the Conductors of the Zoological Journal.] Gentlemen, Your liberal insertion of my former notice of the occurrence of some rare British Birds, has induced me to forward you the follow- ing particulars on the same subject, which I have been enabled to collect within the last four months. Parus biarmicus, Linn. Two nests and the eggs of the Bearded Tit were this year forwarded to London. They were * I judge this to be the fact, from having observed it to be filled with the grains which so eminently characterize the fossils of that locality. The only specimen I have seen I found among some fossils in the Collection of Mr. G. Humphrey. The best account of this mountain and its formations is to be found in Brongniart's Mem. sur les Terrains de sediment superieurs calcareo- trappcens du Vicrntin. p. 27. He has not, however, noticed this species. G.B.S. 86 Mr. Yarrell on the occurrence of some rare British Birds, found in the parish of Horsey, about twelve miles from Yarmouth, in Norfolk. The nest is placed near the ground, being sustained only an inch or two above the surface by the strength of the stems of the coarse grass upon which it is fixed : it is composed entirely of dried bents, the finer ones forming the lining, and others in- creasing in substance make up the exterior. The eggs were four in number in each nest, rather smaller than those of Parus rnajor^ and less pointed ; white, and sparingly marked with pale red irregular lines or scratches. Having obtained nests and eggs, the collector was requested to procure some young birds if possi- ble, and in a few weeks, three, apparently belonging to the same brood, w ere sent up. Emberiza cirlus^ Linn. The Cirl Bunting was this year seen in several instances near Brading, in the Isle of Wight. Two nests with eggs were found, and a third containing young birds. The old ones were observed to feed constantly on the berries of the Woody Nightshade (Solanum dulcamara)^ and a paste made of this berry, wheat flour, and fine gravel, proved excellent food for the young birds, which were reared without difficulty, and are now in high health. Several old and young birds of both sexes were also obtained by shooting. Fringilla Cocothraustes^ Temra. Loxia Cocothraustes^ Linn. The Hawfinch. A pair of these birds bred this summer near Windsor. The nest was not found, but the visits of the young birds to a garden excited attention, and part of the brood was obtained. Charadrius Cantianus, Lath. The Kentish Plover. Two specimens of this very rare species have been shot on the coast of Norfolk, both young birds of the year. The original description of this British bird will be found in the second supplementary volume of Dr. Latham's Synopsis, page 316. Montague considered this bird only a variety of the Ring Plover (Ch. hiaticuld). Having now a young one of each species before me, killed about the same time, and previous to the first moult of either, I shall briefly point out those difieren- Charudrius Cantianus^ and Charadrius hiaticula, 87 ces, which on comparison induce a belief that they are perfectly distinct. The whole length of the Kentish Plover, from the point of the beak to the end of the tail, is five inches and three quarters, the whole length of the Ring Plover not quite seven inches, neither having as yet attained their relative full size. The beak of the first named is wholly black, that of the second has the point black, the base dark orange. The white of the forehead in the Kentish Plover extends over the eye on both sides, forming a conspicuous brow; the same colour in the Ring Plover barely reaches to the eye. The white collar of the neck in the Kentish Plover, extends from the front only a little beyond the ears on each side, and hence the name given to this bird by M. Temminck of Pluvier a collier interrompu. The collar of the Ring Plover is continued all round the neck, having a breadth of a quarter of an inch at its narrowest part. The length of the wing in the Kentish Plover, measuring from the point of the shoulder to the extreme end of the first quill-feather, which is the longest, is four inches and one-eighth ; the same part in the Ring Plover is four inches and seven-eighths. The Kentish Plover has two outer tail feathers on each side wholly white, the Ring Plover but one. The tarsus of the Kentish Plover is rather longer and stouter, but all the toes are one-eighth of an inch shorter than in the Ring Plover, The legs in the Kentish Plover are black, those of the Ring Plover orange. The young Kentish Plover before the moult, has no black about the head, the forehead and brows white, front of the neck the same, the patch on each side of the chest light brown, top of the head, and all the upper parts light ash brown, under parts en- tirely white. M. Temminck in the second edition of his Manual, describes this bird as common in England ; he probably refers to the Ring Plover, about which no such notice is taken, though abundant all round our coast. The two specimens of the Kentish Plover here mentioned are the only recent ones I ever had an opportunity of examining. €8 Mr. Yarrell on the occurrence of some rare British Birds Ardea minuta^ Linn. A young specimen of the Little Bittern was shot during the summer on the banks of the Thames near Windsor: it was believed to have been bred there from the situ- ation being favourable, and the circumstance of a second bird in the same state of plumage being seen about the same spot for several days at that time. Plaialea Leucorodia, Linn. Two specimens of the Spoonbill have been received in London, both of which were shot in Lincolnshire. Scolopax Major.) Linn. The Great Snipe has also occurred three times during the autumn ; two were shot in Lincolnshire, and the third in Huntingdonshire. Tringa pusilla and minufa. These two diminutive Sandpipers, the smallest of the genus, appear to have been constantly con- founded together. Montague has described both, and was aware of the difference, but without venturing to separate them as dis- tinct. Of six specimens lately received in London, two, from the vicinity of Chichester, belong to the species first named, and four to the latter. The Pusilla is rather smaller than the Minuta^ and may be distinguished by the olive-brown colour of the legs, and the short tarsus eleven-sixteenths of an inch in length. The legs of the Minuta are black, and measure seven -eighths of an inch. There is also a marked difference in the habits. The Pusilla resembles the Common Sandpiper (T. Hypoleucos)^ frequenting freshwater streams and ponds a few miles inland. The Minuta prefers the sandy shores of the coast, and when found is generally in company with the Purre. I am, Gentlemen, yours, &c. William Yaruell. Ryder Street, October, 1826. Note. — The Tringa pusilla has also been named T. Temminckii by Leisler. The description of the Tringa pusilla of Linnaeus, does not, according to M. Temminck, refer to either of tli« two European species. M. Buonaparte on Procellaria oceanica, 89 Art. X.

Total length, eight inches and a half. Habitat. The Pacific Ocean and the South Seas ; common near the Cape of Good Hope. Comparative Obs. In comparing this species to the three others, it will be seeii that it is the largest and the more varied with white of the sub-genus, and that is can be confounded only with P. Wilsonii^ to which it bears a strong resemblance in shape and colour, both having the tarsi greatly elongated, the tube of the nostrils equally recurved, the upper tail-coverts entirely w hite, &c. But in addition to its much larger size, proportionally longer bill and tarsi, and lighter colour,* this new species may at first sight be distinguished from it by its wings extending so much beyond the tail, and by the want of the yellow spot on the in- terdigital membrane, which is found in P. Wilsonii only. • In colour it agrees with P. Leachii, which is also next in stature ; but the much shorter tarsi, stouter bill, forked tail, and brown shafts of the tail- coverts of the latter will alweys prevent their being confounded together. I also identified Temminck's P. Leachii with mine a few days ago. Tlie species* is now common in collections. Mr. Vigors's Reply to M, Desmarcst, 91 Art. XL A Reply to some Observations in the ^^ Dic^ tionnaire des Sciences NaturelleSy'^ upon the newly cha- racterized groups of the Psittacidje, By N. A. Vigors, Esq. M,A., F.R.S., and L.S,, S^c, [In a letter addressed to the Conductors of the Zoological Journal. August 1st. 1826.] Gentlemen, I shall make no apology for requesting your insertion of the fol- lowing reply to some strictures which have lately appeared in a French publication on a part of my ornithological labours. The kindness with which your pages have hitherto been opened to me, encourages me to trespass thus far upon you. In some measure indeed I consider myself to have a slight claim to this favour. Your journal has been the channel through which I have promul- gated most of the views that have incurred the disapprobation of the French writer, and ought equally perhaps to be the channel through which I should attempt the vindication of their cor- rectness. There is no task in general more repuguant to my feelings than that of defending myself against the animadversions of my fellow labourers in science. The notice of such attacks upon our opinions evinces too great a susceptibility to criticism ; and lays us open to the imputation that it is ourselves, and not the science we cultivate, that we wish to uphold. The views in Natural science which we advance from time to time in our various speculations ought to be left to answer for themselves : and our only reply to the observa- tions of others should be the alteration of such points as maturer judgment and more favourable opportunities of observation, either on the part of our reviewers, or on our own, have proved to be erroneous ; or the silent retention of our opinions where no ground has been exhibited for censure. Such a mode of reply would exempt *he public from much of the personal feelings of in- dividuals,— a subject at all times of little interest,— and the cause of science would pursue its due course, without the interrup- tion of extraneous matter. In the present instance, however, I 92 Mr. Vigors's Replay to some Observations consider the attack which it is my intention to notice, as rather national than personal. We can not have failed to observe, and to observe with no common regret, that a disposition to depreciate the Zoological labours of this country prevails to a great extent among the Continental writers. And at a period when a new impulse has been given to our science in this country, and a new school of Zoology, if I may so express myself, is forming itself among us, it becomes us to be doubly guarded as to its interests, and not to suffer its rising reputation to be at once overborne by the mandates of assumed authority. It is the wish of vindicating our views against the arbitrary influence which seems exerted to check them in their infancy, and not any personal feelings, that urges me to the present task. The objects aimed at, and the modes of investigation pursued in Natural History, are of such a descrip- tion as to call for the exertions of every man, and the co-operation of every country; but these exertions and this co-operation must be allowed their free course, without limits or restrictions. The republick of science will admit of no dictator. The animadversions io which I would draw your attention are contained in the 39th Volume of the '^ Dictionnaire cies Sciences Naturellesj''^ under the article " Perroquet." They form part of the 20th and 21st pages of that volume, and purport to be a general review of Dr. Horsfield's and my subdivision of the PsittacidcB, The Article is subscribed by the highly respectable name of M. Desmarest. The chief points contained in this critique may be stated as follows. — A general condemnation is inferred of any subdivision in so natural a group, [le genre si naturelj as that which forms the Linnean genus Psittacus. The subdivisions which have been pointed out by Dr. Horsfield and myself are affirmed to be founded on minute differences, without any value, or any apparent regard to the mode of life of the animals that compose them ; — fsur des differences minutieuses, sans aucune valeur, et sans aucun rapport evident avec le genre de vie des animaux dont on les compose]. Most of our groups, it is asserted, have not even the merit of being original. They have nothing new but their names ; " being the same," it is averred, ^' as tliose secondary groups which in the ^' Dictionnaire des Sciences Natiirelles.'' 93 have been long since pointed out, and well distinguished, [tres-bien distingues], by MM. Brisson, Buffon, Vieillot, Le Vaillant, Kuhl, and other naturalists who have made a true progress in this branch of ornithology, without overcharging it with new* and useless denominations." A few minute observations, which shall be briefly noted in their places, against particular names, are added to this sweeping condemnation. When you take into consideration. Gentlemen, the strong and unqualified language in which these censures are conveyed, you will be surprised to learn that the characters and descriptions of the greater part of the genera thus censured are as yet unpublished. Most of the new groups of the Psittacidce^ characterized by Dr. Horsfield and myself, belong to the Ornithology of New Holland, our observations on which are only now in the course of publica- tion in the forthcoming Volume of the Linnean Transactions. I hare intimated this fact in one of the preceding numbersf of this journal; and in a succeeding number I have again merely referred J to these genera, introducing their names only, without entering into any details of the character or habits of the birds that com- pose them ; being unwilling to anticipate observations about to appear in another publication. I do not wish to dwell upon Voe, inconsistency, if not the injustice, of any writer's pronouncing the characters of groups to be minute and valueless before he has seen them. I shall only observe that such a mode of criticism is not founded on the usual principles of reasoning, arid certainly does not accord with the courtesy which generally obtains among naturalists. The time has however gone by, when any individual will be allowed to assume the right of prescribing how Nature is io be investigated. Natural History is no longer an occult science on * I do not exactly discern the force of the above epithets of the French writer. If we give a name to a newly characterized group it must necessarily be a new one. To give an old name would decidedly be an errour. A useless name mu'jt indeed be allowed to be objectionable ; but it niust be proved to be useless before the objection can be made with justice. + Vol. II. p. 61. % lb. p. 400. 94 Mr. Vigors's Re'ply to some Observations which a few of the soi-disant initiated will be exclusively authorised to issue their edicts, as if from an oracle. Like every other subject of research, it is open to the inquiries of every man whose industry or whose opportunities afford a promise of pro- secuting it to advantage ; and like every other science it is to be pursued according to the usual modes and the admitted principles of reasoning. The views and the labours of the naturalist are, in fact, to be praised or condemned, not by the voice of authority, but by their own intrinsick merits or defects. Among the sub- jects which this freedom of investigation has brought before the publick, is the right demanded by every inquirer into nature of characterizing and naming such groups as may appear to him worthy of such distinction : and as far as may be judged from the general practice of the higher naturalists of the present day, this question appears to be decided in the affirmative. The principle of distinguishing new genera seems not only admitted, but, with one or two exceptions, universally acted upon : and the only question on the subject which admits of being canvassed regards the extent or the abuse of the privilege. It is not therefore by the mere force of his own word or opinion that the critick in the " Dictionnaire'^ can now expect to reverse this decree, and proscribe the institution of new divisions in any group, much less in so extensive a genus as that of the Linnean Psittacus, The expression of such an opinion must be considered of no further influence than as it affects the writer's own practice. There is not an argument advanced by him in the work in question to support his opinion ; his remarks are restricted to mere assertion ; and there is nothing new among them which calls for an observa- tion in addition to what has been so often urged on this subject, except perhaps the expression, in which so much meaning appears to be implied, that " Psittacus is a natural genus." Are we to infer from this expression that because a genus is natural, it must not be subdivided ? If so, I know scarcely a group in the modern arrangements of Zoology which admits of a sub- division. Every group is inferred to be natural, that is, to have its prototype in nature, as far as man can understand the original, or it ought not to be adopted. How few for instance of the Linnean in the " Diciionnaire des Sciences Nalurellesy 95 genera are otherwise than natural in this sense of the word. And yet there are few of them, whose extent required subdivision, which have not undergone this process. In the Linnean Mammalia^ for example, Simia^ Vespertilio, Felis^ &c. ; in the Birds, Lanius^ Motacillay Jrdea, Scolopax, &c. ; among the Insects, Scarabosus^ Carabus^ Curculio, PapUioy &c., have all submitted more or less to that necessary subdivision which has brought the numerous species contained in them into comprehensible groups, and yet all are equally natural genera as that of Psittacus. The critick seems in this instance to have founded his inference upon an errour, which I more particularly wish to notice, as I have frequently heard a similar objection advanced in this country against the separation of nearly allied species into generick groups. It would appear as if he wished it to be inferred, that to subdivide is to disunite ; and that such subdivision among naturally conter- minous species makes a breach in their affinities. But the sub- division of a natural group like Psittacus does not infer disunion among its component pafts : the subdivided part still remains an integral part of the more comprehensive group to which it originally belonged. The species of Cercopithecus^ Cynocephalus^ Papio^ Ateles^ CebuSy &c. &c. are as much component parts of the genus Simia^ Linn., as when included indiscriminately and without classification under the latter comprehensive name. No breach takes place in the more enlarged affinities which unites these species into the one general group ; while the more immediate affinities which unite them into minour groups are more clearly pointed out by the subdivision. Nay more, the extreme and osculant species of two separate but conterminous genera may be preserved, by the same mental operation which defines the genera, in still closer contact with each other, than two species even of the same genus, between which other species intervene. The same principle extends in fact through every group of every rank and denomination. Two species of diflferent orders may thus be more closely united in affinity than two species of the same order. The affinity, for example, between a species of the Linnean Strzxy and one of the Linnean CaprimulguSy may be considered more close, although the birds belong to diflferent orders, than the affinity between the two selected species and other species of Mr. Vigors's Repli/ to some Observations 96 their respective orders; that is, between the Strix and a typical species of Falco^ and between the Caprimulgus and a species of Corvus or of Motacilla. In fact our arrangements of natural objects are now founded upon the principle that there are no divisions in nature; and all our nominal divisions are merely mental assump- tions adopted for the sake of convenience. They imply that the mind can keep certain assemblages apart in its conceptions, by fixing upon certain typical modifications of form ; but the names affixed to these assemblages, and the arbitrary limits assigned them in no wise infer an actual separation between them. The very objection which has been subsequently brought for- ward in the " Dictwniiaire" against the subdivisions of the Psittacidce, that they have been previously pointed out by antece- dent w Titers, would, if true, prove that even in the writer's mind the subdivision of a natural group does not infer an unnatural separation. These subdivisions of the French naturalists to which he alludes are noticed by him with every commendation ; and we hear no complaints of their introducing any breach of affinity in " the natural group" of Psittacus. It is true that these latter subdivisions are called sections and have French names assigned them, while mine are denominated genera, and have Latin or scientilick names of distinction. But whatever may be the value of the denomination given to the group, or whatever may be the Iangua£;e from which the particular name of it is derived, the principle which regulates the subdivision is still the same. If there be no difference between the groups themselves, it would be the height of absurdity to suppose that a greater infringement upon the laws of arrangement, as far as they regard affinity, would take place when these groups are called genera, than when they are distinguished by the name of sections. But we must come more closely to this point. In all the other Linnean genera, such as those subdivided groups to which I have alluded above, there seems to have been no hesitation in calling the subdivisions genera. Many of these groups are by no means so copious in species as Psittacus^ which it is to be remembered, con- tains two hundred and twenty-four species, according to the M riter in the " Dictionnaire,^^ Why the subdivisions in the group in the " Dictionnaire des Sciences NaturellesJ''' 97 before us should be called sections, while equivalent subdivisions in equivalent groups are called genera, I can see no reason ; and against the arbitrary mandate that issues such a law I must decidedly enter my protest. I proceed to support this protest by insisting upon the two following points : first, that these subdivi- sions of the Psitlacidce, whatever may be the name by which we think fit to call them, are bona fide genera, according both to the philosophical signification of the terra genus, and the particular adaptation of it to Natural History ; and secondly, that the same groups are marked by equally distinctive characters, and are kept apart by equal differences in the modes of life of the birds which compose them, as are found in any other of the admitted genera in Ornithology. What, in short, is a genus ? Are we to conclude from the ob- servations of M. Desmarest, that there is something sacred in the word, when once it has been attached to a group, that prevents any future interference with it : — that it represents, in short, the real essence of the subjects for which it stands, and will conse- quently admit of neither change nor modification ? Or rather, in accordance with the opinion of one of our first philosophers, should we not consider a genus to " belong not to the real existence of things," but to be " the creature and invention of the under- standing ;" and to represent an assemblage which has been brought together in our ideas by the usual process of generalization, and invested with a name, for the more convenient communication of knowledge ? Such at least is the usual acceptation of the term. — " A general idea^" says Dr. Watts, " is called a genus ^ and it is one common nature agreeing to several other common natures."* — "All the great business of genera and species," observes Mr. Locke, " amounts to no more but this, That men making abstract ideas, and settling them in their juinds with names annexed to them, do thereby enable themselves to consider things, and discourse of them as it were in bundles, for the easier and readier improvement and communication of their knowledge ; which would advance but slowly were their words and thoughts confined only to partfcu- * Logic.

Vol. III. , a 98 Mr. Vigors' s Reply to some Oh sensations lars."* — " The reason," he again resumes, " why I take so par- ticular notice of this, is, that we may not be mistaken about genera and species, and their essences, as if they were things regularly and constantly made by nature, and had a real existence in things ; when they appear, upon a more wary survey, to be nothing else but an artifice of the understanding, for the easier signifying such collections of ideas, as it should often have oc- casion to communicate by one general term ; under which divers particulars, as far forth as they agreed to that abstract idea, might be comprehended."+ One of the chief causes which this eminent philosopher assigns for our not being able '' to rank and sort things, and consequently to denominate them by their real essences," is, " because we know them not. Our faculties carry us no farther towards the know- ledge and distinction of substances, than a collection of those sen- sible ideas which we observe in them ; which however made with the greatest diligence and exactness we are capable of, yet is more remote from the true internal constitution, from which those qualities flow, than, as I said, a countryman's is from the contrivance of that famous clock at Strasburgh, whereof he only sees the outward figure and motions. There is not so contemptible la plant or animal that does not confound the most enlarged understanding. — The workmanship of the all-wise and powerful God, in the great fabrick of the universe, and every part thereof, farther exceeds the capacity and comprehension of the most in- quisitive and intelligent man, than the best contrivance of the most ingenious man doth the conceptions of the most ignorant of rational creatures. Therefore we in vain pretend to range things into sorts, and dispose them into certain classes, under names, by their real essences, that are so far from our discovery and com- prehension."! Still, however, although it must be insisted upon that genera owe their origin to a mental operation, it must be * Essay on Human Understanding. Book 3. chapt. 3. §20. Works, Vol. II. p. 172.

" I would not here be thought," continues Mr. Locke, "to forget, much less to deny, that nature in the production of things makes several of them alike: there is nothing more ob- vious, especially in the races of animals, and of things propagated by seed. But yet, I think, we may say the sorting them under names is the workmanship of the understanding, taking occasion from the similitude it observes among them, to make abstract gene- ral ideas, and set them up in the mind, with names annej^ed to them as patterns or forms (for in that sense the word form has a very proper signification) to which as particular things existing are found to agree, so they come to be of that species, have that denomination, or are put into that classis."*— " This then, in short, is the case ; nature makes many particular things which do agree one way with another in many sensible qualities, and pro- bably too in their internal frame and constitution : but it is not this real essence that distinguishes them into species; it is men, who, taking occasion from the qualities they find united in them, and wherein they observe often several individuals to agree, range them into sorts, in order to their naming, for the convenience of comprehensive signs. — Nature in the constant productions of par- ticular beings make them not always new and various, but very much alike and of kin one to another : but I think it is neverthe- less true that the boundaries of the species whereby men sort them are made by men. — So that we may truly say, such a manner of sorting things is the workmanship of raan."+ * lb.

Mr. Locke was no professed naturalist; — and yet there are observations on nature scattered throughout his works which would do honour to systematists of the highest reputation in our science. The mode in which he alludes to the chain of beings extending throughout the universe, {lb. c. 3. § 12. p. 202.] the imperceptible gradations by which they are united together, and the impossibility of drawing decided lines of demarcation between them might be studied with advantage by those writers who insist upon their groups being founded on decided distinctions. G 2 100 Mr. Vigors's Reply to some Observatiom If then it be admitted that this formation of genera is an opera- tion of the mind, it follows that the same mental operation which created them can alter or modify them as seems proper. And if the genera of Natural History are founded upon the similitude which the subjects of nature appear in our limited ideas to bear to each other, it is according to the increase of our knowledge respecting them, and the more accurate acquaintance which we are enabled to make with their qualities, that our changes and modifi- cations taost be regulated. It is also evident that in the process of generalization the term genus may be philosophically applied to every group of every degree in the series. Particular denominations may, it is true, be applied to the several groups which represent different stages in this process; and when a science or subject becomes complex, such denominations must necessarily be assigned for the purpose of |)ointing out the value of each group as it occupies a higher or a iower rank in the general scale. In Geography, for instance, the different combinations represented by the words County, Province, Kingdom, Empire, &c. ; in Military Tacticks, by Company, Battalion, Brigade, Division, &c. ; in Natural History, by Family, Order, Class, Kingdom, &c., are more definitely pointed out by such terms than if we were to call them genera with numerical or other distinctions. Still such groups, although for the sake of perspicuity, invested with such particular titles, are neither more mor less than genera. We may even again make intermediate stages amidst these already admitted combinations, and we may call them by such names as sections, or subdivisions ; or subking- doms, subclasses, or subgenera; or in short by any other term which appears most appropriate to our purposes : but every such intervening combination will still be found to represent one com- mon nature agreeing to several other common natures, and, as such, it is strictly and logically a genus.* * For the reasons assigned above, I have always felt adverse to the use of the term subgenus, although it has been sanctioned by the highest authority. There is a sort of anomaly in the word as generally applied. A subgenus is, strictly speaking, a species ; genus being the proxinaate group to species, according to the usual acceptation of these terms. It is true that all these terms are merery in the '^ Dictionnaire des Sciences Naturelles,^^ 101 Species also is equally with genus the creature of the under* fitanding. It may be equally applied to all the groups in the scale of generalization, unless to that which we consider the highest genus. Both these terms are in fact relative, and are used perhaps with logical correctness only when an immediate reference is made to each other. The same group is a genus or a species, ac- cording to the relative place which the mind assigns it in our ascending scale. " These universals are genuses," says Dr. Watts, " if compared with less common natures ; and they are species, if compared with natures more common. So Bird is a genus, if compared with Eagle, Sparrow, Raven, which are also common natures ; but it is a species., if compared with the more genjeraj nature, AnimaL'^* conventional, and if naturalists agreed among themselves to use that of sub» genus in the same sense as section or subdivision, there is no reason why it should not be adopted. But something more is inferred in these subgenera tiian their being merely sections of a genus. They are elevated into a higher rank by being distinctly characterized and separately and scientifically named; and herein lies the main objection. When we give a name to what we call 9, subgenus, we intend that name either to be used or not. If the latter is our intention, we fall into the errour of increasing the number of names without any ostensible benefit. If we mean on the other hand that the name should be used, we create confusion between the generick and subgenerick name. We will take an example from the highest source. The sacred beetle of Egypt belongs to the genus Scaraboeus, M'L., and to the subgenus Tleliocantharus^ M'L. Are we to call the insect Scarabceus sacer, or Heliocantharus sacer? Were we to decide on calling all species belonging to a subgenus by the sub- generick term, we fall moreover into the inconsistency of designating equivalent species by titles of unequivalent value. Some species will have a generick and some a subgenerick title. Cetonla aurata for instance, and Heliocantharus sacer, although insects of equal importance, have names, the first as generick, of higher, and the latter as subgenerick, of subordinate value. The uniformity of nomenclature, one of its highest merits, is thus sacrificed to what can only be called a temporary expedient. If in fact we consider our groups to be worthy of separate characters and separate names, there is no reason why they should not in the first instance be called genera, and the higher group receive a deno- mination of still higher import. We thus at once meet and overcome the difficulty that is imposed upon us by the influx of new forms, and number-f less species, without exhausting our efforts in the vain endeavour to defer ^ jreform in nomenclature which must ultimately be adopted. * Logic. Part I. chapt. III. Sect. III. Note 1st. p. 35. 102 ' Mr. Vigors's Reply to some Observations There is this particularity however in Natural History that these terms of genera and species have been particularly adopted for groups of an ascertained rank in the scale of generalization. For the greater convenience and precision of communication, as well as to preserve uniformity in scientifick nomenclature, it seems to have been agreed upon by common consent that every subject in natural History should be designated by two names, one more general, the other more specifick ; the first to point out the group in nature to which it appears to belong, the second to point out the especial station it holds in that general group. By equally common consent, and for reasons which must be obvious to all,* the two groups which are pointed out by the selected names are those which represent the two first combinations formed in the act of generalization as the mind advances upwards from indivi- duals. To these combinations the terms genera and species are respectively applied per excellentiam. And thus these terms, which in their original acceptation might have designated every assemblage of every rank in the series of generalization, assume a definite signification when applied to Natural History ; species denoting the proximate group into which individuals are united by some quality or qualities common to all, and genus the proxi- mate group into which species so formed are similarily united. Were the subjects of Natural History like those of many other branches of science, definite in their numbers, and well ascertained * The chief advantage resulting from the use of the proximate genus is the brevity attending it. The tediousness of summing up all the various more remote terms is avoided by using one which comprehends all. When we name a subject in Natural History by the usual terms of science, I consider that we in some measure may be said to give a definition of it. Now the correct mode of defining any thing, is " by joining the general and special nature together, or (which is all one) the genus and the difference." [Watfs Logic. Pari I. c/^. I V. j». 94- 3 Dr. Watts sufficiently explains the reason, why the genus thus used should be " the nearest genus." [lb. p. 95.] Mr. Locke also notices the quickness and brevity resulting from the use of the proximate genus. " This may show us the reason why in the defining of words, which is nothing but declaring their significations, we make use of the genus or next general word that comprehends it. Which is not out of necessity, but only to save the labour of enumerating the several simple ideas which the next general word or genus stands for." [Book 3. ch. 3. § 10 ] in the " Dictionnaire des Sciences Naturelles.^^ 103 as to their qualities, the groups into which they are assembled might be considered equally definite. The value of these groups would be invariably the same, and the names chosen to represent them might be set down as fixed, and at all times proper for the purposes of communication already stated. Simla might thus always continue Simia, and an original PstUacus, according to the views of M. Desmarest, be a Psittacus to the end of time. But there is this peculiarity in Natural History, particularly in its earlier stages beyond which it can scarcely even now be con- sidered as having advanced, that the number of its subjects can be reduced to no limits. Every day's experience proves that their increase eludes all our efforts to circumscribe them. It conse- quently happens that the original groups, which at first were proximate in our ideas to species, cease to continue so ; and the mind seizes upon intervening characters of distinction by which it is enabled to reduce the increasing subjects within a comprehen- sible compass. The limits of species may perhaps be considered capable of being defined, although I must confess I think even this point problematical ; but until our knowledge of nature becomes perfect, — a period little to be expected, — the next proxi- mate groups to species must ever be subject to variation. A single instance will illustrate this remark, as well as point out the process by which the mind endeavours to proportion its groups to the increasing number of the subjects brought before it. Lin- naeus, in his attempts to reduce the Coleopterous Insects into order, observed several species among them which bore a similitude to each other in their general structure, in having apparently six paipiy and in their antennce being filiform. He characterized this group accordingly ; and as it was the proximate group to species he called it a genus, and distinguished it by the name of Carabus, The number of species known to him amounted to forty-two. Small as was this number, in comparison to that known in our days, it appears that he considered it too extensive for a single group, and he accordingly made an artificial but still a convenient subdivision in it according to size; separating the species into majores and minores. As the subject began to be more closely investigated, the discovered species became excessively numer- 104 Mr. Vigors' s Repli/ to some Obstrvations ous, the original tens increasing to hundreds ; and new leading characteristicks were selected to distinguish them, such as the emargination of the anteriour tibice, the abbreviation of the elytra^ the pcdunculation of the abdomen^ &c., &c. By these means such groups as Harpalus^ Lat., Brachinus^ and Scarites, Fab., the true Carabus^ &C.5 intervened between the original genus Carabus^ Linn., and the species of that group; and as these groups now became proximate to species, they virtually became genera in their turn. These genera again, as science advanced, were found in- conveniently prolifick in species, those of the original Linnean group, amounting, as has been lately observed,* to sixteen hun- dred j and more minute but still important characters of distinc- tion, such as the different forms of the several parts of the trophi^ the shape of the thorax^ the relative proportions of the joints of the aniennce, &c., fee, were still further resorted to for the purposes of subdivision. Intervening assemblages thus crept in between these latter genera and their species. And to select one of them for an example, Harpalus was resolved into Chlwnius^ Bon.^ Ca/ascopus^ Kirby, Dicoelindus, M'L., the true Harpalus of Authours, and several similar groups, which, being now proxi- mate to species, respectively assumed the title of genus according to the peculiar acceptation of that term in Natural Science. In this process the original groups of Carabus and Harpalus^ which had successively filled the place of genera, having become of a still more comprehensive nature, received appellations of a pro- portionally higher value ; and they are now distinguished as a family or a stirps according to their respective station in the series. It cannot be here concealed that the apparent closeness with which such investigations are carried on has brought down some reflexions on the modern naturalist. It has become the fashion of late to inveigh against this minuteness of research, and to allege that the higher views of the science are sacrificed to subordinate and petty details. I cannot subscribe to this doctrine. In making a comparison between the earlier and present views of the science, "we must take into consideration the relative knowledge of both times. And when we find that a single genus of Linnaeus, his * Annulosa Javunica. Pari. \. p. 11. in the '^ Dictionnaire des Sciences Naturellesy 105 Scarabceus or Carabus for example, is now as extensive in species, as his entire Coleopterous order, we must admit that as ample a field for the higher speculations of science is open to the naturalist even in the former apparently subordinate groups, as Linnaeus had before him in a group of what is deemed the most comprehensive description. Nor is our process in the distribution of the species of such groups confined, as is frequently objected, merely to analysis. As much combination is employed in comparing and bringing together the allied species, as analysis in subdividing the higher group. And if the synthetick mode of reasoning is to be pronounced the superiour means by which the naturalist arrives at his conclusions, — a gratuitous assumption, however, for Natural Science while it investigates every property of the subjects before it, should equally employ every means in the investigation, — that mode is now not only equally made use of, but is carried to a greater extent than at any former period of the science. We cannot in fact employ the analytick mode of research in the present state of the science without the synthetick. We analyze the genus by synthesizing the species. But this is merely a negative view of the merits of the modern process. A positive advantage conspicuously results from this closeness of investigation. Cha- racters are brought into notice which were overlooked in the earlier stages of science : and in proportion to the extent to which characters of every description become known, is our knowledge advanced of the relative stations in nature of the groups in which they are found. We can form but a contracted view of the natural world when we found our arrangements upon one or two properties or characters only. Such a process may lead to a knowledge of differences, but never can advance the discovery of affinities. It is only by the comparison of all the qualities of groups, as far as the naturalist can discern them, that their affinities and analogies can be satisfactory detected ; and thus only can we attain the probability of making our representations of nature bear any similitude to the true and only system. The very minuteness of our mode of research thus eventually conduces to its comprehen- siveness; and upon these very details are founded the highest and most generalizing views of the science. 106 Mr. Vigors's Repli/ to some Observations But to return to the subject more immediately before us.— From the foregoing observations and the authorities which have been adduced to corroborate them, it may be summarily concluded that the subdivision of an extensive genus like Psittacus is not merely philosophically correct, but conformable to the usual process employed in Natural Science. The only groups whose value and denomination can be in any wise considered definite, are species. All the superiour assemblages of every degree are perfectly arbitrary, and are subject to variation as the species included in them, and the modifications of form discernible among these species, call for further subdivision. The only question to be considered in respect to this subdivision is the im- portance of the characters on which the intermediate groups are founded. We are thus brought to the second point which I had proposed to notice ; and I shall proceed to the examination of the chief objection which has been levelled against the new genera of the Psittacidw, that they have been instituted " upon minute and valueless differences." If I were asked to point out what appears to be the greatest modern improvement in Natural Science, I should say that it is that mode of arrangement which results from the conviction that there are no divisions in nature ; and in which accordingly groups are established, not upon the difference, but upon the variation of their characters. The naturalist seeks out the typical characters of his larger groups at the point where they appear most strongly developed, and then tracing their various modifications until they may be said to evanesce, and give place imperceptibly to the succeeding characters of the neighbouring groups, he fixes upon these various modifications as ideal marks of separation between his subdivisional groups. He is in this manner guided, not by detecting distinct or opposing characters, but by tracing out the modifica- tions of the same. The first suggestion of this mode of viewing nature, in contradistinction to that which is founded upon a supposed separation of groups, was made by Linnaeus, whose maxim " Natura ubique varia semper tamen eadem^^^ directly acknow- ledges this principle. He had not himself materials sufficient to act upon it invariably ; and yet many of the genera which he in the " Diclionnaire de Sciences Naturelles,^^ 107 either originally instituted or adopted from others, such as Lanius, Turdusy and Motacilltty for example, or Fringilla and Loxia^ originated in this mode of viewing nature. We may trace the same principle through most of the genera which have been still more lately instituted, although it does not appear that the authours of them were aware of the principle which guided them. Totanus^ Limosa, Scolopax, Rhi/nchcea^ Tringa^ with in- termediate groups ; Pastor and Lamprotornis of M. Temminck ; Dendrocolaptes^ Certhia^ and Ortlionyx^ as lately characterized ; — all these, and in fact almost all the allied groups of modern terms, if closely investigated, will be found to exhibit no difference in characters, but merely variations of the same. The genus PlU' tijrhynchus^ the only group Avhich at this moment I remember to have been instituted in ornithology by the naturalist whose name is subscribed to the critique in the '' Dictionnaire^^^ possesses no characters, at least if we may judge of it from the types which M. Temminck has given in his '' Manuel^'''' but what are modi- h cations of those of Musdcapa and Miisdpeta. This was one of the leading principles which actuated Dr. Ilorsfield and myself in our subdivisions of the Psittacidce, One of the chief typical characters of the group appeared to us to con- sist in the strength of the bill. Formed for breaking the hardest vegetable substances the typical bill seemed to be indicated, as in the group of Maccaws (Macrocercus, Vieill.,) by iis shortness, height, and solidity. In these birds the height from the mentum to the forehead at least doubles the length from the rictus to the apex j the under mandible, instead of being elongated, as is usual among birds, is bent inwards with a strong emargination ; while a line drawn from the centre of it to the apex^ the head of the bird being in the regular erect position, is nearly vertical. On the other hand the aberrant bill may be pointed out by its decreas- ing strength and greater elongation, as in the group of the Indian Lories. Here the length is not less than the height ; the under mandible is entire ; and a line drawn from the centre of it to the apex^ the position of the head being as before, is nearly horizontal. These modifications of the characters of the bill evidently point out a corresponding modification in the nature of the food of 108 Mr. Vigors's llfply to some Observations the family, and indicate a variation in that food as it gradually descends from the hardest to the softest vegetable substances. In addition to these characters others have been taken into con- sideration, which appeared to us of no mean value ; such as the form of the wing and tail, and the relative proportions of the feathers of each ; the greater or less elevation of the tarsi; and the structure of the tongue. These appear to be characters which are not only prominent and easily recognized, and at the same time indicative of various modifications in the economy of the birds in which they are found ; but characters which have already been employed as of the highest imj)ortance by those naturalists who have established leading groups in our science. The characters, for instance, taken from the structure and proportions of the wing and tail must be considered of primary consequence, as more or less conducive to the powers of flight : — powers, which it may be recollected form one of the typical dis- tinctions between Birds and the other ^ertebrata. It conse- quently becomes a leading object of the naturalist to point out the perfection or deficiency of these organs of flight by the most marked distinctions in his power. In the present family he finds an occasion of peculiar interest for the exercise of this privilege. We may remember that the group of the Perching Order, which approaches most closely to the Rasorial, is the Tribe of Scansores, One of the characteristicks by which this approach is indicated is the decreasing powers of the wing in the Scansorial Birds, And the naturalist, in marking the modifications by which these latter birds gradually pass into the Ea^onVi/ families, whose typical station is on the ground, and who consequently require no superiour powers of flight, is enabled to point out more strongly one of those beautiful affinities by which nature connects her leading forms. The greater or less elevation of the tarsus of a bird is again a character of much consequence, as indicating its habits to be more or less terrestrial. And accordingly we find many important groups, such as 3Ii/ioihera^ 111., and Pilia^ Vieill., among the Thrushes; and Saxicola, Bechst., and Brachi/pteri/x, Horsf., among the IVarblers ; With several others of acknowledged importance, established chiefly upon the modifications of this character. Here in the ^^ Dictionnaire des Sciences Naluiellesy 109 also ill the family before us we find thai the investigation of this peculiarity leads to a speculation of more than ordinary interest to the inquirer into affinities. Of the two orders now brought into comparison the typical station of the Perching Birds is on trees, of the Rasorial Birds on the ground. But the extreme Tribe of the former Order, or the Scansorial Birds» are found to seek their subsistence by running or walking up the stems of trees in a mode corresponding with that of the Rasorial Order on the ground. The trees, if I may so express myself, are to them the ground. Now if we find these walking and running habits oi the Scansores still further developed, and that some of the groups actually feed, not on the trees but on the ground itself, we shall have occasion to notice a still nearer approach, and a still more immediate interchange of character, between these neigh- bouring orders. This we find to be the case in an extensive group of the Psittacidce^ which comprises the ground Parrakeeis of Australia, or the genera Nanodes^ Plafycercus^ and Pezoporus ; as well as in a group of the Picidce^ or Woodpeckers^ distinguished by Mr. Swainson under the title of Colaptes^ and which includes the Pic laboureur of M. Le Vaillant and several American species. These birds with the general characters of the Scansores occupy the same terrestrial station as the Gallinaceous Birds ; and while the other typical species of their Tribe may be said to be walkers or runners up the trees, they may be pronounced to be climbers on the ground. This interchange of character is emi- nently beautiful and well deserves the attention and the distinction of the naturalist. Nor is the structure of the tongue a character of less im- portance. Many well established genera, and groups of even still higher value have been separated in consequence of the modifica- tions of this member. The Woodpeckers^ the Creepers^ and the whole of the Mellivorous Birds may be selected as examples. The typical tongue of the Parrot is so well known, and has been an object of such familiar observation in ?\\ ages, that any devia- tion from the ordinary form appears to lay claim to even peculiar attention. But while this deviation among the Parrots is interest- ing with reference to the birds of their own group, it becomes 1 10 Mr. Vigors's Replz/ to some Observations doubly so in consequence of the station which the group itself holds in the great series of ornithology. We may observe that the whole of the birds which feed chiefly or exclusively by the tongue, whether upon insects, or upon vegetable juices, such as the birds already mentioned, including the families of Picidcoy and CerthiadcEy and the five families of the Tribe of Tenuirostres. are united together by one continued chain of affinities, and may be arranged in one contiguous group among the Insessores. Now the birds that come next in affinity to the Picidce^ which com- mence this series of tongue-feeding Birds, are the Parrots. The approach in these latter birds to the typical character of the con- spicuous assemblage which succeeds, consequently exhibits another striking instance of the mode in which nature gradually blends the characters of her groups into each other. And the naturalist who marks this gradation by a strong distinction gives additional truth to his ideal representations, and strengthens their similitude to the disposition of nature which they profess to copy. Such are the considerations and such the characters upon which the subdivisions of the Psittacidce have been founded. With all due deference to the authority of the critick of the " Dictionnaire,'^ I cannot persuade myself, that, either viewed abstractedly, or with reference to the characters on which other groups have been established in ornithology, they are " minute and without value." How far these characters have "any regard to the mode of life of the animals which compose them," has already been partially pointed out. And I think I shall sufficiently illustrate the dif- ference in the manners and habits of. these birds by instancing three species ; whose economy I will assert,— and let it be re- membered that assertion is the only argument made use of by my opponent, — exhibits as strong marks of distinction as that of any other species of a natural group, which have hitherto been considered worthy of generick separation. The birds I shall instance, are, the Maccaw, breaking with its powerfully constructed bill the hardest vegetable substances in the tropical forests of America; — the P/a^^c^rcw*, with its comparatively feeble bill seeking a softer substance upon the ground in ihe high latitude of Macquari: ie's Island, where not a tree is to be seen ; — and the de- in the '' Dictionnaire des Sciences Naturelles.^'' Ill licately formed Trichoglossus^ with its filamentous tongue find- ing its support in the temperate climate of New Holland among the never-failing blossoms of the Eucalypti, The fact is that if we do not characterize these and similarly circumstanced groups, when the opportunities, which the singular advantages of this country afford, occur for this purpose, the task will be undertaken by others. The experience of every day proves that this will be the case. In the last number of this journal I had occasion to refer to some new genera which have been lately characterized on the continent in this very family of P^zY^ttczV/cp; and one in particular, the genus Aratinga of M. Spix, which accorded with my group of Psittacara. I could point out more- over several groups in Natural History, whose separate existence as genera have been merely indicated by some of our naturalists, who refrained from naming them in deference to the opposition that was raised against the institution of new genera ; and which groups nevertheless were subsequently named and characterized by the very writers who were the most forward in declaiming against the practice. I shall now. Gentlemen, beg leave to draw your attention to the second chief allegation of the writer in the '' Dictionnaire^^' that the new groups of the Psittaddce have not even the merit of being original. I shall not trifle with your time so far as to dwell upon the decided contradiction between this observation and the pre- ceding animadversions which I have just disposed of. If Dr. Horsfield's and my groups of the Psittaddce are the same as those of antecedent writers ; and if the latter groups are deserving of the praise of being, as is stated, " well distinguished," surely ours can with little propriety be asserted to be founded on '' minute and valueless differences." Nor shall I allow myself for a moment to suppose that the critick means to insinuate by this observation that either Dr. Horsfield or myself would claim any credit (if credit is due upon such points) by appropriating to our- selves the fruit of the labours of others. Were such an allegation to be preferred, I have only to refer back to the pages of this journal, where some of the groups of the Psittaddce have been characterized ; and where it may be seen how far I have been ll!8 Mr. Vigors's Repli/ to some Observations either ignorant of the labours of antecedent writers, or unjust to their merits. I hasten at once to the more immediate point of the justice of this censure. You will bear in mind, Gentlemen, that the main assertion of the critick, when he opposes the high pre- tensions of so many of the continental ornithologists to our humble exertions, consists in these two points ; — that these writers have already "well distinguished" our groups, and distinguished thera •without '' overloading the science with new names." M. Brisson stands the first upon the list ; a name of deserved reputation in science. But let it be recollected that not a single species of New Holland Parrots upon which the greater part of our new groups are founded, has been described in the *' Ornitho- logie.^^ The divisions of the Parrots indicated by M. Brisson, with the doubtful exception of Lorius,* in no respect interfere with ours. They can scarcely be said to be " tres-bien distingues;" for the characters, which, it is to be observed, are not formally detailed, as is usual in Natural History, but only incidentally hinted at in the introduction to the species, are drawn merely from the colour or size of the bird, or the length or shortness of the tail. While, strange to say, our only guide to these divisions are their names. And Jra, Cacatua^ Lorius, Psittacus^ Psittaca^ * M. Brisson has pointed out several subordinate groups among his genera, which he indicated merely by giving them names. The groups which he considers as real genera, are distinctly marked out by full distinguishing characters ; but the minour groups are not even set apart as sections or sub- genera, or as any of those subdivisions with unassuming titles which, with- out aiming at the importance of genera, form the nucleus of future groups of generick, or even of still higher, degree. These names of M. Brisson I consider merely as so many suggestions ; and as he hesitated himself, indeed declined, to make them generick, we cannot now in correctness quote them as such. The rule should be invariable, that no group should be considered the genus of any naturalist that is not decidedly characterized and named by him. It is for this reason, that I decline calling the group, alluded to above, the Lorius of M. Brisson, although he certainly pointed it out by name. It is true that he has gone farther in pointing out the subdivisions of the Parrots than of any other of his genera : as he mentions some of their less important characters in the general introduction to the genus. But still he withheld from separating them as genera; and we consequently cannot attri- bute to him a group, which he virtually refused to establish when he had the opportunity of doing so. in the '•^ Dictionnaire des Sciences Naturelles,^^ 113 Psiitacula, names without any characters, or at least such charac- ters as are adequate to scientifick purposes, stand in direct con- tradiction to the assertion of M. Desmarest. M. BufFon succeeds. No man will venture at this day to dis- pute the claims of this pre-eminent naturalist to the highest rank in science: but no man, I conceive, will be hazardous enough to attribute those claims to his views of arrangement. In fact he professedly set his face against all systematick forms ; and when he was obliged to institute some necessary subdivisions for the sake of perspicuity, he founded them upon the most inconse- quential characters, such as colour, locality, &c. What for in- stance are his subdivisions of the Parrots ? + I shall select an example as quoted in the Article itself before us, the writer of which pronounces with so much authoritativeness that these groups are " well distinguished." The whole of the Parrots have been separated by M. Buffon into two primary sections ; — those of the Old World, and those of the New. Such a division evidently dis- arranges the affinities of the subordinate groups ; both continents possessing species, which, if not strictly belonging to the same group, belong at least to groups immediately connected by affinity, and which nevertheless, in the arbitrary geographical arrangement are disjoined from each other by a considerable interval. I shall add the following example, which will sufficiently point out the scientifick value of the subordinate groups. The American Parrots with even tails are divided into — Amazones^ with yellow on the head and red on the carpal joint of the wing; — Cricks^ smaller in size, without yellow on the head, or red except on the coverts of the wing ; — Papegais, still inferiour in size, without any red on the wing. Here then in the second instance of the high-sounding authorities paraded against us in the '' Dictionnaire^''^ I may be allowed to assert, that the groups of M. BufFon are not " well dis- tinguished," according at least to the usual modes and principles of science ; and that they are set apart " by names." - + If we turn to the 21st page of the 2nd volume of M. Le Vaillant's " His- ioire des Perroquets" we shall find how much the opinion of that naturalist, no inadequate judge on such a subject, is at variance with the assertion of the writer, in the " Dictionnaire," that M. BufFon's groups of the Parrots are *' tres-bien distingues." Vol. III. H '114 Mr. Vigors' s Reply to some Observations The name of M. Vieillot follows in order. To him science is indebted for the first institution of the genera Macrocercus and Plyctolophus among the Psittacidce} for he also, — to quote the words of the critick of the •' Dictionnaire" against himself, — has ^'overcharged this department of ornithology with new and useless names." In what manner these groups or any other divisions which that naturalist may have noticed in this family interfere with Dr. Horsfield's and my groups, 1 have yet to learn. Of all the naturalists who have paid attention to the PsittacidcBy M. Le Vaillant went the furthest in indicating the natural groups of the family. Three out of nine of the new genera named by Dr. Horsfield and myself conjointly, or by myself solely, have been pointed out by him. These groups indeed exhibit such strong marks of distinction, that they could scarcely have escaped so dis- cerning and sciehtifick an observer as M. Le Vaillant. I can only wonder at his having passed over the other groups without notice, such for instance as the Trichoglossiy the structure of whose tongue appears to have been long familiar to ornithologists. Had he given scientifick instead of provincial names to the groups which he pointed out, my task in referring to his labours would have con- sisted only in quoting these names, as I have quoted those of M. Vieillot or M. Illiger. But it was not M. Le Vaillant's custom, nor was it consistent with his views, to designate his subdivisions by the usual terms of science. It does not however follow, that, because he was inimical to scientifick names, others should be debarred from conferring them. And it consequently may be seen that some of the best known and most interesting groups in ornithology are those which M. Le Vaillant first pointed out, but which succeeding naturalists united more uniformly by the usual technicalities to the ranks of science. I shall instance the genera Indicator^ Phoenicophaus^ and Coccyzus of M. Vieillot, which cor- respond with the groups IndicateurSy Malcohas, and Couas pre- viously pointed out by M. Le Vaillant. When in the course of my inquiries I had occasion to refer to the groups which had been already noticed by M. Le Vaillant under the names of Perruches d queue enjieche^ Perruches a large queue, and Perruches- Aras^ I followed the long-established and approved of practice of in the '' Dictionnaire des Sciences Natureiies,^^ 115 assimilating them to other equivalent scientifick groups by terms equally scientifick. And, in describing and dwelling upon the species of Palceornis^ Platycercus, and Psittacara, I feel some con- fidence that I may be considered by you, Gentlemen, and those who are equally aware of the nature of my pursuits in science, to have had some more ^audable object in view than the miserable reputation of conferring k name. M. Kuhl concludes this list of the writers on the PsittacidcB ; — the list at least of these who are named ; for there are still others alluded to by the critick, with whom we may yet hope to be made acquainted by his means, who '' have truly advanced this depart- ment of Ornithology without overloading it with new and useless denominations." In a former number of this Journal* I have expressed my sense of the obligations due to M. Kuhl for his Monograph on this family. By referring to my observations it may be seen that he has divided it into six primary groups, none of which in any respect come in contact with Dr. Horsfield's and mine. Ours in fact are subdivisions of two of his sections. By referring to the same observations it may also be seen, that these groups of M. Kuhl are not " tres-bien distingues" according to the usual practice of naturalists ; and that, in contradiction again to the assertion of the writer in the ^' Dictionnaire^^^ they are dis- tinguished by names. I fear. Gentlemen, you will consider that more attention has been bestowed upon these trivial points than they merit. I have not however entered upon this defence of Dr. Horsfield and my- self from a conviction of the importance of the attack made on us, but for the purpose of exposing the spirit in which this attack has been made. Would that our views had been more ably canvassed, and by an opponent, and in a mode, more worthy of our reply ! In such a case the higher principles of the science might have been discussed with advantage to both parties, and the truth even- tually have been elicited by the collision of opposite opinions. At present it is our misfortune to have to deal with mere assertion unaccompanied even by an attempt at proof, and unqualified con- demnation without the decency of an argument to support it. * Vol. II. p. 48. n2 lid Mr. Vigors's B.e'ply to some Observations Yet amidst the dearth of interest that pervades the present con* troversy, — if controversy it can be called, — some points of im- portance occasionally exhibit themselves ; and to one in particular which involves a question of some moment in nomenclature I shall beg leave more closely to draw your attention^ Id looking to the observations contain'^d in this letter, and to those in a former volume,* vrhich referred to the groups of the Falconidce^ you cannot have failed to observe that an attempt has been made, by the opponents of the modern genera in Ornithology, to introduce these very genera under the denomination of sections, and with names derived from their own language, in preference to names according with the usual language of science. Although the title of genus is denied these groups, still are they virtually Separated as genera, virtually characterized as genera, and vir- tually named as genera. The whole credit of forming the group, as well as the name thus falls to the share of him who by the simple process of sinking the title genus ^ and the scientifick name of the first characterizer, appropriates the group to himself. In this manner the Astur of M. Bechstein, or the Milvus of M . Cuvier, may be claimed as the property of M. Desmarest or M. Temminck, or any other declaimer against new genera, under such denominations, translated for the most part from the original, as les Autours or les Milans. This attempt at superceding the use of scientifick names by the introduction of French names is beginning to be carried to an extent which leaves no doubt of the ultimate object in view. In almost all the professed works of science, it is the French word that is quoted,and not the scientifick.t In the very '' Dictionnaire" before us the same language furnishes the title of every article to which we are to refer, whether be- ♦ Vol, I. p. 189. + A single instance vrill point out the extent to which this practice may be carried. M. Vieillot some time since characterized a most important and well- defined group among the Laniadee which he named ThamnopMlus. M. Tem- minck introducing this genus into his " Manuel,^^ gave it, as is customary a familiar name, that of Batara. Having occasion to refer to this group, which decidedly is M. Vieillot's, the naturalist of the " Planches Coloriees,'* looking only to the familiar name which he himself had given it, considers it and calls it his own genus. His words are " men genre Batara.^* [PI. Col. Art. Barita destructor, pi. 273.] in the ^' Dictionnaire des Sciences Naturelles^ 117 longing to a genus or a species. It is Perroquet we must consult, not Psittacus. The French word is every where the protagonist of the piece, and if the scientifick name is at all introduced, it is in the character of an humble companion in the suite of synonyms. If this practice is not met by us with decided opposition in the outset, it will gain ahead against which we shall in vain endeavour to contend. I do not oppose this mode of nomenclature on the narrow ground of every language having an equal right with the French to become the language of science : but upon the broad principle, that there should be but one common language ia science ; — that every nation should unite in one universal mode of nomenclature which could be generally understood ; — and that naturalists should endeavour to imitate the harmony observable throughout the objects they cultivate, by the only means in their power, however humble these may be, — a corresponding harmony in their language. In choosing this common language it is un- necessary to contend for the superiour claims of that which is founded on classical authority. Time and science have equally sanctioned the use of it. No modern terms, however important to the nation which furnishes them, could be otherwise than trivial, and sometimes even ludicrous, in the eyes of others, in comparison with words derived from a Greek or Roman source. The contentions that so frequently break out among the chief introducers* of these familiar terms sufficiently proves the in^ stability of the foundation on which they wish to erect their nomenclature. And it certainly is from no blind partiality that I would bestow a preference on such words as Plyctolophus, Macro- cercus, Pezoporus, or even Palceornis, over such names, although sanctioned by the pen of a BufFon, as Cricks^ and Papegais^ Per-^ ruches and Perriches. I have already mentioned that objections have been started against the names of some of my groups. These objections I shall now briefly notice, not because I consider them of import- ance, but to point out how far the same spirit of cavilling without » See particularly the observations of M. Vieillot in opposition to some of M.Temminck's familiar names; [Nouvtnu Diet. cTHist. Nat. Art. Ornitho§ logie,] and M. Temminck's in answer ; [Manuelj Introd. p. xii.] 118 Mr. Vigors's Repli/ to some Observations any just grounds pervades the whole of this criticism in the " Die- tionnaire." The term Palceornis^ for instance, is asserted to be inapplicable to all the species comprised in the group for which it stands, — " there being," as the critick declares, " but one species of Psittacus known to the ancients, — namely the Psitt, Alexandria I would here ask this writer whether he imagines that every species in a group partakes equally of the characters of the type, or is pointed out with equal significance by the name assigned the type, when that name happens to be expressive of some attribute or quality ? If such is his opinion, he will find few natural groups in modern arrangements that will exactly square ■witli his views. If he goes back to the days of Linnaeus, he may notice that truly accurate observer referring to the '' notce aber- rantes" which distinguish some species of a group from those which are typical in it, and which nevertheless do not virtually detach these species from it. A significant name stands on the same ground as a character ; and does not lose its general appli- cability to the group on account of the deviation of some species from the type, or " ob speciei notam aberrantem,^^ But even were this not the fact, the writer's observations are totally in- applicable to the case now before us. Palceortiis is the name of a genus, not of a species or individual. And the critick must prove his censure to be correct, by shewing that this genus or group was not known to the ancients, — an assertion even by his own admission contrary to the fact, — and not by objecting that any of the species were unknown to them. In naming a Parrot^ we will say for example, Palceornis ert/throcephalusy we do not advance the proposition that the bird so named is a red-headed bird known to the ancients^ but that it is the red-headed species of a group which was known to them. Even a New Holland species may be, and indeed has been, found, which as a species must be decidedly considered as unknown to classical times, but which, by possessing the same character as this ancient group, must be included in it. And this being the case the name of Palceornis, as generick, is strictly applicable to it. But where has this writer discovered that one species only of in the '' Dictionnaire des Sciences NaturellesJ^ 119 Parrots was known to the ancients ? iElian, no slight authority on such a subject, expressly states the contrary : and had the writer in the " Dictionnaire" taken the pains to read the paper which he has undertaken so unequivocally to condemn, he would have found his censures as little founded upon fact, as upon the accurate modes of reasoning. From the following passage of the Greek authour quoted in that paper [p. 64.], it appears that at least three species of Parrots were known in ancient times. — Ey h^ots (/.xv^xvu airracKHs o^vis yivs^ixi. — FENH TPIA ccvruv xxau.^ I have not the good fortune of a personal acquaintance with M. Desmarest : I know him only by his writings. But, with that proneness which we all feel to exalt the votaries of the science we ourselves pursue, I have been accustomed to class him in tny imagination among those higher naturalists, whose qualifications make up the deau ideal of a man of science. Familiarized with the writings of our earlier ornithologists, of Ray and Willoughby, of Pennant, White and Montague, and conversant with the modes of thinking and discussing that belong to most of the living naturalists of this country, I had been led into the opinion that it is the characteristick of a man of science to unite to a knowledge of his immediate pursuits, the accomplishments, and the courtesies of a gentleman. I had equally persuaded myself that, amongst these accomplishments, a knowledge of classical literature was at least a valuable embellishment, and an adherence to the rules of fair and legitimate discussion, a qualification that was essential^ How great then was my disappointment, when I perceived the name of M. Desmarest subscribed to an article, where on a clas- sical subject an unpardonable ignorance was betrayed of classical literature, and where at the same time the common rules of justice and courtesy were violated by the indiscriminate abuse of a paper, which appears not merely not to have been studied, but not even to have been read ! I shall not however allow my good opinion of M. Desmarest to be so easily overturned. I shall quote his own words in his own vindication ; and I shall appeal to M. Desmarest when speaking the sober language of science, from M. Desmarest when scattering * Hist. Animal. Lib. xvi. c. 2. 120 Mr. Vigors's Repli/ to some Observations the random and inconsiderate hallucinations of criticism : — In the former character he simply declares the fact, — " Les anciens ont connu plusieurs perroquets^ parmi lesquels le plus celebre est la perruche envoy ee de PInde par Alexandre "[p. 10.] ; in the latter capacity he either forgets this fact, or wilfully misrepresents it ; — " Le nom qu'il [le genre Palceornis'] recoit semble indiquer que tons les oiseaux qu'il renforme etoient connus des anciens, et cependant il rJ'y en a quhm seiil^ la per- ruche d'Alexandre" [p. 20.]. — What inference are we to draw from the contradiction that thus sets these adjoining pages of this writer at variance ? Are we to conclude that it is Homer himself that nods? Or rather have we not two Homers *' in the field"? My genus Platycercus is equally unfortunate as Falceornis. The name, as it appears by the critick's account, is inapplicable to several species enumerated in the group, namely Plat. Pacificus^ Ulietanns^ cornutus^ and auricepsy inasmuch as these species have narrow and pointed tails, [queues aiguees et pointues,] not broad tails [queues plates] as the term would import. I should here, Gentlemen, apply the same observations respecting the aberration of character in the extreme species of a group which I have advanced in the preceding case of Palceornis^ did I not conceive that I should be trifling with your time and that of your readers, by not at once meeting the assertion of the writer in the '' DiC' tionnaire^^ by a decided contradiction. The species enumerated above certainly forma small minour group in the genus, as I have myself elsewhere observed. They are geographically separated from the others, being found in the Australian islands, not on the continent of New Holland ; and deviating from the typical species by some subordinate variations of character, they probably will hereafter form a new genus when further subdivision becomes necessary in this branch of the family. But although the tail of these species is more graduated than in the typical species Plut. Pennantii, and thus points out the passage to Pezoporus, it is yet so conspicuously broad at the base and centre, as to be fully entitled to the character I have assigned it of being "lata, de- pressa," and thus to bear out the applicability of the title Plattjcercus to the whole group. The three last mentioned in the '' Dictionnaire des Sciences Naturellesy 121 species of this group are of rare occurrence. I have met with specimens of them only in the British Museum ; and there only I believe the greater part of them are still to be found.* These specimens are not in the best preservation, but they evidently accord with the characters I have assigned them, as may be judged from the figures given of them in a preceding volume of this jour- nal. But although these species are rare, the Plat. Pacificus has become of late very abundant in our collections, and I have thus been enabled to speak with certainty as to its characters. I have had a living specimen for months in my collection, and have besides seen numbers alive in this town ; where they have been the subject of general admiration, not merely on account of the length of their tarsi and the consequent activity and freedom in running and jumping which so strongly distinguishes them from the generality of ParrotSy but on account of the equally dis- tinguishing breadth and depression of the tail.t * Although it is rather a bold step to assert that any writer would describe the characters of birds without having seen the birds themselves, particularly when he opposes the opinions of another writer on the same subject, I would almost venture to suggest that the writer in the " J)ictionnaire" had never seen the birds in question. M. Kuhl described these species from the specimens in the British Museum; and looking only to the one conspicuous character, the length of the tarsi, he classed them with the Pez. formosus, III., which is distinguished by its length of limb. He was not aware that all the Perruches d /ar^e jMcrae have elevated tarsi: and that the species alluded to would thus have more properly been arranged in that group on account of the form of their tail. Now it appears probable that the writer in the "• Dictionnaire" looked, not to the birds, but to M. Kuhl's Monograph; and finding them ar- ranged with a bird that has a narrow cuneated tail, he took it for granted that their tails must also be " aiguess et pointues." Whatever may have been the cause, he certainly is in errour respecting the fact. f It happens by a rather curious coincidence of circumstances that the only, or at least the best known group in Ornithology which has been formed by M. Desmarest, has a name derived from the same source as Platycerciis. I allude to his genus Platyrhynchus. It also happens, that the same characters, mutatis mutandis, would answer for both members that respectively supply the names. The bill of his group is broad and depressed at the base and centre, and tapering towards the apex : so is the tail of my genus. A horizontal section of the bill of PlatyrTiynehus would accurately represent the tail of Platycercus. M. Desmarest ought to be more cautious than to permit a censure to pass under his authority upon a mode of nomenclature which is sanctioned by his own practice. 12:^ Mr, Vigors's Replt/ to some Observations One observation more and I have done. The late M. Kuhl, in his Monograph of this family, introduced a practice which well deserves to be imitated, that of placing in a separate station at the end of his Paper all the published species which he had not him- self been able to examine, or which had not been described from authentick sources. Among these doubtful species was the Psiit» pyrrhopterus of Dr. Latham, which, having been described from a single specimen, and a specimen no longer it appears in ex- istence, or capable of being referred to at the time M. Kuhl wrote his Monograph, might with some appearance of justice be assigned this doubtful station. Two living specimens however lately ar- rived in this country from the Sandwich Islands, and came into my possession ; they were immediately characterized and figured in this journal. In the very face nevertheless of this evidence of its existence, the bird, although referred to in the '' Dictionnaire^^ as published in this country, still retains its station in that work among the doubtful species. Here then we have a bird, described by one British naturalist, redescribed by a second, and figured by a third ; and yet in the eyes of M. Dcsmarest, or rather I should say, of his inefficient substitute, it is not of sufficient authority to hold a place among authenticated species. I trust. Gentlemen, that, in thus defending Dr. Horsfield and myself against the uncalled for attack that has been levelled against us, I may not be supposed to be actuated by hostile feelings to the French naturalists in general. Those readers who may have paid a casual attention to my exertions in science, must be aware that I have been neither ignorant of the eminent ser- vices in Zoology of our continental neighbours, nor backward in acknowledging them. If there are any of those my exertions upon which I can allow myself to indulge a moment's pride, it is the endeavour, in union with some of the most enlightened Zoologists of this country, to break through the restricted mode of studying nature that has retarded the growth of the science among us, and to open the eyes of our rising naturalists to the improvements of the continental schools. It has been one of our chief objects to point out the true merits of the founders of these schools ; — not, however, with the view of following in their wake, in timid sub- in the " Dictionnaire des Sciences Naturelles*^ 123 mission to their ordinances, but in the hope of emulating their progress and maintaining an equal line in the advance ; — of assum- ing, in short, that forward station in Zoology, which the genius, the industry, and the mighty resources of this Empire confer upon us as a right, and impose upon us as a duty, to assert. Happy am I in feeling myself authorized to add, that the spirit which is diffusing itself among our Zoologists promises the happiest results to this our cause. We feel strong in our first advances. We have chosen our path : — not having fallen into it by blind chance or wayward prejudice ; but having selected it from all that lay before us, with free and deliberate preference. And in full confidence, as far at least as human reason and foresight can inspire us with con- fidence, of having chosen the right way, we shall steadily pursue it, uninfluenced either by the secret or undisguised opposition of false friends or open enemies, abroad or at home. Truth is our object; — trutli if possible in amity with all — in cordial co-operation with all I but, — if that boon be denied us — still truth and truth alone. I must conclude. Gentlemen, this long discussion into which I have been forced most unexpectedly, and entirely in opposition to my wishes and feelings. I conclude it however, as I hope I have pursued it, without any sentiments or expressions of resent- ment. My feelings are more those '' of sorrow than of anger ;" — of sorrow, that the fair fame of a naturalist like M. Desmarest should be hazarded by being placed in contact with the ill-judged Article before us, and that the pages of science should be sullied by contentions such as these. I have the honour to be, Gentlemen, &c. &c. N. A. Vigors. l,^4r Anali/tical Notices of Books. Art. XII. Analytical Notices of Books, An Introduction to Entomology : or Elements of the Natural History of Insects, By William Kiuby, M.A. F.R.Sf L.S. cwf/ William Spence, Esq. F.L.S. Vols. iii. «wrf iv. 8vo. pp. 732 and 634. Plates xxv. To furnish a satisfactory analysis of any production on Natural History in a few lines, barely exceeding in number that of its sheets, must be at all times a task of extreme difficulty. It is one which in fact could never be attempted with any prospect of success unless where the work under examination was chiefly theoretical. By reproducing the conclusions arrived at by the author, and exhibiting some of the more convincing arguments adduced in support of them, a tolerably correct idea might in such a case be given. Where however the work, like the one before us, is almost entirely free from theory, and is devoted with very trifling exceptions to the exposition of facts, the attempt to analyse it becomes completely hopeless. The '^ In-r troduction to Entomology" is indeed itself an analysis of the numerous volumes devoted to the history of Insects which have preceded it ; all that is valuable in their contents being con- densed in its pages within the smallest compass consistent with perspicuity. The information derived from these sources may consequently be regarded as beyond the reach of a still farther abridgement. On the other hand the novel facts with which it abounds, and the new views on many most important points which are illustrated in its course, are almost equally beyond our power to analyse : they are tpo numerous for the space we could afford to them, and too interesting to be condemned to the cur- sory notice to which we must be confined. Were we indeed to set aside the whole of the materials derived from the works of previous authors, and to advert solely to those novelties for which we are indebted to Messrs. Kirby and Spence, a review conducted on our usual principle of retaining all the important facts pre- sented to us, would become by far too extensive. Each of the Kirby and Spence's Introduction to Entomology, ISS Letters into which it is divided would require an article more extended than the present, and the whole of one of our numbers would scarcely suffice to convey an adequate outline of the vast mass of important information embodied in these volumes. Our ndtice must therefore be limited almost to a mere enumeration of some of those striking points by which the attention of the scien- tific reader will be most forcibly arrested. The remainder we must, though reluctantly, pass by, with the single observation that there are few pages of the work from which Entomologists, even of the highest order, will not derive at once information and amusement. Of the contents of the first two volumes of the Introduction to Entomology it is unnecessary for us to speak, as they are doubtless well known to every one of our readers. In the pre- sent volumes, which complete the work, the subjects are thus arranged: definition of the term insects; states of insects; their external anatomy ; their internal anatomy and physiology ; their diseases ; their senses ; Orismology, or explanation of the terms employed in Entomology ; systems ; history of the science ; geo- graphical distribution of insects; methods of collecting and pre- serving them ; and the mode to be pursued in their investigation. On the first of these subjects, the definition of the term Insect, Messrs. Kirby and Spence differ from all previous systematists, the characters employed by them being designed to embrace all those annulose animals in which respiration is performed by means of tracheae. Their Insecta consequently correspond with the Insecta and the Trachean Arachnida of Latreille and Lamarck ; with the Insecta^ Acari^ and Mi/riapoda of Dr. Leach ; and with the Mandibulata^ Haustellatay many of the Arachnida^ and nearly the whole of the Ametabola of Mr. W. MacLeay, The only an- nulose animals excluded are the Arachnida^ distinguished by hav- ing sacs for respiration, and the Crustacea^ in which that office is performed by gills. The function thus relied on for their chief distinction is one of undoubtedly primary importance, and the division deduced from it is shown to be strongly supported by •the differences observable also in the systems of circulation, di- gestion, and generation. The relation borne by insects to other 1^6 Anali/tical Notices of Books. animals is also pointed out, and their resemblances in many par- ticulars to the more perfect of the Vertebrata are traced with some detail. That, though usually minute, they occasionally exceed in size animals of a higher organization, is shown by a curious table of the comparative magnitudes of insects of the different families. The succeeding Letters are devoted to the different states of Insects. The authors combat the hypothesis recently advanced by Herold, that the successive skins of the caterpillar, the pupa- case, the future butterfly, and its parts and organs, except those of sex, do not pre-exist as germs, but are formed successively from the rete mucosum by a vis formatrix. Against this they argue at considerable length, and adduce several weighty reasons for the preference they give to the older opinion of Swammerdam, that every caterpillar, at its first exclusion, contains within itself the germ of the future butterfly. Through their succeeding stages of Egg, Larva, Pupa, and Imago, the history of insects is traced in that attractive style and with that perspicuous arrange- ment which characterize the work. The number of eggs laid by insects, the moulting of the larvae, the cocoons of the pupae, their transformation, and especially the development of the wing of the perfect insect from the almost shapeless mass formed by it in its rudimental state, are among the topics most ably discussed in this section. The differences existing between the sexes are also explained with considerable detail. But the most striking novelty in this department, as connected with system, is the extension of the views of Mr. W. MacLeay relative to the analogies borne by the larvae of certain insects to the Ametabolous Annulosa^ into other orders besides the Coleoptera, in which alone they had before been extensively developed. In addition to the resem- blances of form traceable between larvaj and the AmetabolUy many are pointed out between them and the various orders of Crustacea^ the Arachnida^ and even Mollusca : on the latter analogy it is however probable that some doubts may be enter- tained. Of the fifteen types of larvae thus obtained, characters and examples are given ; and their occurrence or prevalence is carefully traced, through each of the orders of insects respec- Kirby and Spence's Introduction to Entomology. 127 tively, to the greatest extent that our limited acquaintance with them will at present permit. Of the high scientific value of the information presented by the Letters on the external Anatomy of Insects it is almost impossible to speak in terms of sufficient praise. To estimate rightly its im- portance it would be necessary to have devoted, like Mr. Kirby, years to the investigation, and to have carefully examined, with an acumen equal to his own, almost every entomological collection in this country and many in foreign lands. On this subject it may safely be asserted, that no one need fear to lower his own importance by exclaiming to our authors, in the words of Linne on another entomological occasion, Estote magistri mei. The immense mass of novelty introduced in this department, a novelty of facts and not a mere pernicious alteration of names, is preceded by a synoptical table of the parts into which the insect skeleton is resolvable. The whole of these are subsequently treated of with a detail which leaves nothing to desire. The description of the head, and of those essentially important por- tions of it, the trophi or organs by which the food is taken, is particularly laboured ; but we cannot even enumerate the many striking facts deduced from the accurate dissections to which insects of every order must have been repeatedly subjected during its composition. Even for the parts of the perfect mouths defi- nitions are given more precise than any previously proposed ; while to the imperfect ones are applied denominations so correctly circumscribed as to obviate in future that misapplication of terms by which considerable confusion has hitherto been produced. In connexion with the head, another set of organs is now for the first time pointed out as appertaining to a sense usually supposed to reside in other parts of the body — that of smelling. The Clypeus is regarded as a nose, Nasus, and the Rhinarium, situated between this part and the lip, is considered as analogous to the nostrils of quadrupeds. That the sense in question resides in this situation seems almost to be established by the facts adverted to in a subsequent Letter. The trunk is submitted to an equally minute investigation with the head. It is divided primarily into Mani- trunk and Alitrunk, the anterior pair of legs being denominated 128 Anali/tical Notices of Books. Brachia, their functions frequently resembling rather those of arms. The parts composing the three segments of the thorax are minutely described, and their internal processes are especially attended to. The structure, forms, and areas of the wings, their appendages and modifications ; the legs, their articulations and locations, and the parts of the tarsi, are also treated of in detail. This portion of the work furnishes indeed in every respect by far the most complete view, both general and partial, of the external anatomy of insects that has ever appeared. The Letters on the Internal Anatomy and Physiology are de- Toted in succession to the systems of Sensation, Respiration, Cir- culation, Digestion, Secretion, Reproduction, and Motion. Each of these presents too vast a field to be touched on by us ; but we cannot refrain from noticing the opinion advanced by Messrs. Kirby and Spence, that the nervous system of insects is of a mixed kind, combining in itself both the cerebro-spinal and the ganglionic systems. On the external resemblance borne by their first ganglion to the brain in vertebrated animals it must be con- fessed that too much stress ought not to be laid; but their capa- bility of domestication and of education, or in other words of acquiring habits not instinctive, their memory, and their possession of that degree of intellect and judgment which enables them to profit by the notices of their senses, appear to us, as to our authors, to furnish so many convincing proofs of the necessity of a common nervous centre. The recent anatomical discoveries of Miiller, which will be noticed in our next number, are also adapted to illustrate and support, in a very striking and unexpected manner, the opinion just alluded to. At first sight the subject of the Letter on the Diseases of Insects may appear to partake of the ludicrous. They are how- ever at times annoying to man, those of bees and silk-worms being occasionally extremely detrimental to their proprietor, and the hopes of the aurelian in his choicest larvae being frequently blighted by them. Unfortunately the healing art has yet efi'ected little to remedy them. Their history is in many respects interest- ing, and the descriptions of various malformations and deformities are particularly curious. Kirby and Spence's Introduction to Entomologi/. 129 On the organs of the Senses in insects there exists so consider- able a difference of opinion, that the Letter on them will probably prove one of the most generally attractive. That insects possess senses equivalent to, if not identical with, those of the human race, is rendered evident by numerous facts with which all are conversant. Few however entertain precise ideas as to the organs by which are received the impressions of external objects. Our authors regard the Antennae, relative to whose functions so much discussion has taken place, as the analogues of ears ; the sense of hearing being however probably modified by some connexion with that of touch in a manner of which we can form no clear con- ception. Touch, in a passive sense, appears to be pretty generally diffused over the body ', active touch is stated to be confined to the antennae, palpi, and arms. Smelling is, as we have before observed, referred to the nose and to the space included between it and the lip : and taste to the tongue. With respect to the organs to which sight is entrusted no dijBiculty appears to exist. The Orismology of this department of Natural History is another of those topics to which, as to the external anatomy, the attention of the authors has been especially directed. The im- portance of a well-defined system of terms is too obvious to re- quire illustration. Without a thorough and clear acquaintance with them it would be impossible either to receive or to convey correct scientific information. The terms proposed by Messrs. Kirby and Spence seem perfectly adapted for general use. They are precisely defined, and as they are by far more numerous thaa those previously in use, they of course comprehend a greater number of those variations in substance, forms, surface, and relative situation, on which reliance must always be placed in the investigation of insects. Each of them is moreover illustrated by a reference to that part of some particular insect in which it is found to exist, and a correct idea of its precise meaning is thus ensured. In the nomenclature of colours this plan is almost essential, words alone being scarcely capable of conveying ac- curate impressions of numerous shades which are readily distin- guished by the eye. Vol. III. I ISO Analytical Notices of Books, The Orders adhered to in the letter devoted to the System of Insects, are those proposed in the first volume of the work. On this occasion the essential characters of each are given, and these are accompanied- by observations on their connexion with each other, and on the tribes of which each is individually com- posed. Of the existence of a primary division of winged insects into Mandibulata and Haustellata^ doubts are entertained ; and it is stated that, on the principle of their formation, a third section should be adopted to include many of the Hymenoptera^ by which the food is taken by lapping. The analogies which are considered to exist between the Orders, approach nearly to those remarked by Savigny. They are drawn from the resem- blances of the perfect insects, and thus differ essentially from those deduced by Mr. W. MacLeay, from the metamorphosis. The relative value of the groups, both primary and subordi- nate, into which insects are divided, is explained, and they are made to succeed each other in the following order : class; subclass ; order ; suborder ; section ; subsection ; tribe ; sub- tribe ; stirps ; family ; genus ; and subgenus. For nearly the whole of these divisions uniform terminations are proposed ; a plan which, could it have been originally carried into elBfect, would have admirably expressed the comparative importance of the group intended to be mentioned, but which would now ne- cessitate too many changes in received nomenclatures to become ever available. The position assigned to insects in the general system is in immediate apposition with the Vertebrata. The History of Entomology is divided into seven Epochs ; the Era of the Ancients ; the Era of the Revival of the science after the darkness of the middle ages ; the Era of Swammerdam and Ray, or of the Metamorphotic System ; the Era of Linne, or of the Alary System ', the Era of Fabricius, or of the Maxillary System ; the Era of Latreille, or of the Eclectic System ; and the Era of MacLeay, or of the Quinary System. The sketch is clearly and candidly drawn up. Each of the eras passes succes- sively in review ; the system proposed in it is examined, and the principal alterations suggested by real science, or by a mere affectation of novelty, are explained. Hence a general view Kirby and Spence's Introduction to Entomology, 131 is obtained of the progress of Entomology from its first dawning as a science to the present advanced state of knowledge respect- ing it. A very curious illustration of the Linnean system is given in a copy of Latin verses by the peet Gray, in which the characters assigned to each of the genera are exhibited within the compass of a single hexameter. In the letter on the Geographical Distribution of Insects, many valuable facts are thrown together in illustration of the limits within which certain families appear to be either almost entirely confined, or at least especially prevalent. The enquiry is one which is now regarded with considerable interest, and for the elucidation of which fresh materials are daily accumulating. Under the same head much information is imparted relative to the stations and haunts of insects, the seasons of their appear- ance, and their times of action and repose, which will materially assist the collector, for whose instruction the subsequent letter is also designed. In this the instruments and methods usually employed in their capture are fully described ; and the best plans for preserving and arranging them are pointed out. The want of such a manual as is here furnished has frequently ope- rated to paralyze the exertions of the unpractised collector, and we are therefore gratified to observe it embodied in a work which will find its way into so extensive a circulation as the present. The plan recommended to be pursued by the student in the investigation of insects, will also be found highly service- able to him, and will doubtless receive that attention to which every observation on this subject, from such a quarter, must be entitled. .The Appendix presents a list of the authors quoted, which is so arranged as to afford some idea of the works which are most necessary to an entomological library ; together with very copious indexes, an essential appendix to every work of science, and tables of reference to the numerous objects represented in the well-filled illustrative plates. The descriptions of the organs of generation and of the coitus are here also given, but are shrowded from many of the readers of the more popular portions in a learned language, which has evidently been resorted to for 1 2 132 Analytical Notices of Books, the sake of decency. A curious instance of the zeal with which occasions for inculcating lessons of piety and morality has been sought after here occurs, in the hints given for the guidance of young ladies on subjects of which they should scarcely be sus- pected to have even dreamed, and in a language too which few of them can understand. So slight a slip of the pen needs how- ever no apology in the kindly and good-hearted feelings which evidently dictated it. Confessedly imperfect as is the preceding sketch of this ar- ranged Encyclopaedia of entomological knowledge, we feel less hesitation in presenting it to our readers, since we are convinced that the perusal of the volumes themselves will be universally sought after. It would be almost superfluous to add, that they will at once gratify and instruct every admirer of that extensive and interesting department of Zoology of which they treat. The task undertaken by the learned authors was most arduous, and one from which men of less energetic minds must have shrunk in despair. To maintain and even to increase by the publication of a work almost essentially popular, the high scientific characters which they had previously obtained, required a fortunate com- bination of talents of no ordinary description. To have succeeded in such an undertaking to the extent which has been effected by them, an extent probably greater than their most sanguine hopes could have anticipated, affords the most convincing proof of the admirable nature of the plan pursued by them ; a plan, be it added, formed upon no preceding model, but meriting ffs a new invention, to be held forth to the iinitation of others. By their excellent Introduction more general attention has been at- tracted within a few years to the study of Entomology than would have been produced in centuries by a repetition of those dry technicalities which so frequently check the ardour of the beginner, and occasionally disgust him at the very threshold of the science. The happy union of amusement with instruction obviates this difficulty : the learner is interested in the wonders displayed before him, he pursues the study with vigour, and while endeavouring to verify by experiment the statements of his authors, becomes himself acquainted with new facts ; these he Sowerby's Genera of Recent and Fossil Shells. 135 in turn imparts to the world, and thus, should ambition urge him so far, he is at length eni'olled among the more distinguished votaries of that science in which he has found the recreation and delight of his leisure hours. That such results will again and again be produced by the labours of Messrs. Kirby and Spence, we confidently expect. In other departments of Zoology the same end would doubtless be attained by the employment of similar means, and we do hope that these means will not be suffered to remain wanting while we have those among us whose talents and acquirements have peculiarly fitted tljiem for sup* plying the deficiency. The Genera of Recent and Fossil Shells. By G. B. Sowerby, F.L.S. WUh original Plates. % J. D.C. Sowerby, F.i..5. No. xxviii. The whole of the four genera illustrated in the present number are new ; two of them being now, for the first time, separated from Voluta, Lam., one from Venus ^ Lin., and the remaining one |3eing founded on an undescribed species of Cirripeda. The first of these genera, Cymba, is thus characterized : ^' Testa levis, admodom ventricosa, plerumque uni- color. Epidermis laevis, fusca, tegmine quasi vitreo partim vel omnino obducta. Apex rudis. Spira brevissima. Columella curva, 2-3-plicata, plicis magnis, acutis. Labium externum haud re-^ flexum. Basis profunde emarginata. Apertura hians. Oper- -culum nullum. Caput grande, planum, tentaculis remotis, oculis pone tentacula posjtis, mediocribus. Pallium magnum ? Peg maximus. Animal carnivorum. Habitat marinum in calidioribus mundi veteris regionibus. It includes six species, formerly part of the section Gondolieres of Lamarck's Voluta^ and is illustrated by figures of C. Neptuni in a young state, of C. Cymbium^ and of C. proboscidalis. The second genus Meld, also forms part of the same section of Foluta, Lam. The character assigned to it is as follows : ^' Testa ventricosa, levis, ut plurimiim colore vario. Epidermis 134 Analj/tical Notices of Books, laBvis, viridi-fusca. Apex mamillaris. Spira brevis. Columella ■vix recta, 3-4-plicata5 plicis magnis, acutis. Labium externum haud reflexum. Basis profunde emarginata. Apertura hians. Operculum nullum. Caput grande, planum, tentaculis laterali- bus, remotis, oculis pone tentacula positis, magnis. Branchiae satis magnae, dextra major. Pallium mediocre. Pes maximus, ovalis." The animals of this genus resemble those of the pre- ceding in being carnivorous, and in inhabiting the seas of the warmer regions of the old world. The species are divided into two sections, 1. "Spira inermi," including only the M, Indicus (V. Melo, And.) which is figured, together with its young state, V. Pneputiuniy Chemn. and 2. " Spira spinis fornicatis armata," embracing six species, and illustrated by the figure of a new one under the name of M. umbilicatus. For the characters of, and observations on, the two preceding genera, Mr. Sowerby acknowledges himself indebted to W. J. Broderip, Esq. who has kindly in part anticipated the information he is about to publish in his Monographs of the VolutiddSj for which his extensive collection aiFords the most ample and satis- factory materials. PuLLASTRA, in which are included the Venerupes of Lamarck, together with such of his Veneres as are allied to V, pullastra^ is thus defined by Mr. Sowerby : " Testa aequivalvi, transversa, inaequilaterali, latere antico breviore, dentibus cardinalibus in utraque valva tribus contiguis, interdum apicibus subemargina- tis. Impressiones musculares duae laterales, subrotundatae. Im- pressio muscularis pallii sinu magno. Ligamentum externum^ valvarum marginibus dorsalibus suboccultatum." It is illus- trated by figures of the P, vulgaris^ Venus Pullastra^ Auct., of P. litteratUj and of P. papilionacea. The new genus of Cirripeda is described under the name of Catophragmus : " Testa subconica, apice pervio, basi adhse- rente, (valvS, testacea clausa?) valvis octo, inaequalibus, late- raliter adjunctis, composita ; valvis porro plurimis per series externas, circulares, gradatim minores, confertim co-ordinatis. Operculum bipartitum, valvis quatuor, anticis majoribus, compo- situm." As in the new genus Odomeris established by Mr. King's Survei/ of Australia. 135 Sowerby, at page 244 of our last volume, and figured in the Sup- plementary plates, the shelly cone immediately surrounding the animal consists of eight pieces, and the operculum of four ; but in CatophragmuSy the first shelly cone is surrounded by a second, equally composed of eight pieces, and this again by several sets of more and more numerous pieces gradually dcreasing in size, bearing in this respect some analogy to Pollicipes, The genus is founded on two specimens in different stages of growth, one of which was received from Antigua, attached to a Conia. The trivial name affixed to it is C imbricatus. Narrative of a Survey of the Intertropical and Western Coasts of Australia^ perfot^med between the years 1818 and 1822, By Captain Philip P.

To enter at any length into the general results of this inter- esting survey of the coasts of New Holland, would be foreign to the purposes of this Journal, in which we are bound to con- fine ourselves to the zoological information obtained during the progress of the expedition. It will be sufficient to observe that the whole of the Eastern Coast within the tropic was carefully surveyed, as well as the Northern and North-western Coasts, on each of which, and also at the Isle of France, were collected objects of Natural History, few certainly in number, (owing to the rarity of the occasions presented by the nature of the service, and to the want of sufficient space in the small vessel employed,) but by no means without that interest which arises from the no- velty of some of them. A brief review of the Catalogues of the collections in the various departments of zoology, which form part of the Appendix, will best illustrate their value to the student. The Mammalia, only six in number, present nothing worthy of remark : but of the fourteen species of birds collected, no less than four are regarded as new by Mr. Vigors, to whom Capt, 136 Anali/tical Notices of Books, King acknowledges hjmself indebted for advice and assistance in this department. One of the new species, which is closely allied to the Gracula viridis, Lath., is considered as forming, to- gether with that bird, a new genus provisionally described tinder the name of MimetA, with the following characters : " Rostrum forte, subuarcuatum, subcultratum, mandibulis utris- que apice emarginatis ; naribus basalibus, lateralibus, subovali- bus, membrana partim tectis. Lingua ad sugendum idonea? Al(B mediocres, rotundatae ; remige Ima brevissim^ ; 2da et 6ta aequalibus ; 3tia et 4ta fere aequalibus, longissimis ; 5ta his paulo breviori : riemigum 3tia ad 6tam inclusam pogoniis exter- nis in medio gradatim productis. Pedes subbreves ; acrotarsiis scutellatis, scutis quinque ; paratarsiis integris. Cauda medio- cris, fere aequalis." The stability of this genus, which has many external relations with the Orioles, rests entirely on the probability that the tongue is formed for suction. Should this prove not to be the case, the group, it is allowed, must of course fall. The new species described is the M. Jiavocincta, " flavo- viridis, subtus pallidior, capite dorsoque fusco-lineatis, alis cau- d^que nigris viridi flavoque variegatis." It differs from the M. viridis in the bill being somewhat higher, and more carinated, in the general distribution of the colours, and in being marked with yellow where the latter bird is white. The remaining ornithological novelties relate merely to species. The Hcematopus picatus " ater ; corpore subtus, fascia alarum, uropygio, caudaeque basi albis ; remigibus primoribus totis ni- gris ; " forms the second addition to this genus recently obtained from Australia. It approaches more nearly to the European species, the H. ostraleguSy than to the H.palliatus of Temminck, or to the H.niger of Quoy and Gaimard. The Sterna pelecanoidesy '^ alba ; capitis vertice nigro albo-variegato ; dorso, alis, rachibus albis," deviates from its own genus, and approaches the Pele^ canida by the smaller size of the membrane that unites the toes, by the dilatation of the side of the nail of the middle toe, and by the greater proportional length of the wings. The fourth new species Larus GeorgUy is thus described, '' L. albus, dorso ali&que nigris ; rectricibus albis, fascia media atra." King's Survei/ of Australia. 137 For the illustration of the Reptilia^ nine in number, we are indebted to Mr. J. E. Gray, who considers four of them as new. One of these is peculiarly remarkable by the singular frill ap- pended to the neck, which distinguishes it in a striking manner from the Agama, to which it appears in other respects to be closely allied. It is the type of the genus Chlamt/dosaurus^ Gray, Ann. of Phil., and is thus described ; " C. Kingii, C. corpore luteo, nigro-variegato ; squamis carinatis ; pennula an. tice serrata ; caudae corpore duplo longiore." Another is refer- able to the genus Phelsuma^ Gray, ib. where a short character of '/ it, under the name of P. ornata^ had been previously given. The third forms the type of the genus Trachysaurus^ Gray, and is characterized as follows ; " T. rugosus, T. squamis dorsi ru- gosis, caudae subspinosis ; cauda brevissima : " and the fourth is the Leptophis punctulatus^ " L. squamis laevibus apice uni-inden- tatis, spinas dorsalis triangularibus ; cauda quadrantali, tenui, squamis aequalibus ; " an interesting addition to the genus esta- blished by Mr. Bell at p. 328 of our last volume, to which an- other species collected by the expedition, the L. spilotuSj (Coluber spilotus^ Lacepede,) is also referred by Mr. Gray, The Lacerta scincoides, Shaw, is described as the type of the genus Tiliqua, Gray, 1. c. under the trivial name tuberculata. Among the Fish described, which are only seven in number, one alone, the Teuthis australis^ is stated to be new. Mr. Gray, however, has since ascertained that it is probably the Acanthurus triostegus. He remarks, that seven or eight other species, and several interesting drawings, were brought home by Captain King, which may probably be novel, but which he fears to describe as such lest he should increase the confusion already existing in this neglected department of Zoology. With the exception of a single species of Annelida^ the whole of the Annulosa collected are illustrated by Mr. W. S. Mac- Leay. The number of species of insects enumerated or des- cribed in the Catalogue is 192, of which 130 belong to the class Mandibulata^ 58 to Haustellata, and 4 to Arachnida. Of these eighty-one were previously undescribed ; but the whole of them except two, are referable to genera already established or indi- 138 Analj/tical Notices of Books, cated. The genera now first admirably described in detail are Carpophagus, the type of which is the C. Banksia^ and Mega- MERUS, having for its type M. Kingii^ a singular insect, bearing an affinity to Sagra^ but differing from that genus in having seti- form antennae, correct mandibles, (almost resembling those of some of the Prionij) and securiform palpi. In another respect the latter insect is extremely interesting, as the discovery of pentamerous tarsi in a genus so nearly allied to SagrUy has led Mr. MacLeay to investigate minutely those parts in the tetra-^ merous and trimerous Coleoptera of the French Entomologists ; the result of which examination, as developed in a paper read before the Linnean Society at the commencement of the last year, has been to establish that those divisions are utterly un- founded in fact. Both the Carpophagus Banksia and the Mega- merus Kingii are figured, together with the Phasma tiaratum^ a rare and singular species. Of Cirripeda only one species is mentioned ; and of Radiata no more than five : the species of Acrita are twenty-five in num- ber ; but the whole of these have been described. The Mollusca^ illustrated by Mr. J. E. Gray, are more nume- rous, comprising one hundred and eleven species, twenty-three of which are new. None of them however present any striking novelty of form ; those which were previously undescribed being referred to the following genera ; Venus ^ Cytherea^ Lima, Mono- donta^ Rissoa^ Solarium, Phasianellay Scalaria, Littorina, Nassa, Claratula, Conus, Marginella, Strombus, Bulla, Cyclostoma, Chiton, and Haliotis, To transcribe the characters of these new shells would too much extend this notice, and the reader who wishes to consult them must therefore be referred to the work itself. He will also be repaid for a perusal of the general narra- tive, by numerous occasional notices on such zoological subjects as presented themselves to Capt. King's observation. It is gratifying to observe that the able navigator and zealous naturalist, to whom we are indebted for these volumes, was in- structed by the Secretary for the Colonies " to endeavour to obtain information " relative to " the animals, whether birds, beasts, or fishes ; insects, reptiles, &c." which might be observed Curtis's British Entomology, 139 during the progress of the expedition. By the same authority directions were also given to " receive on board Mr. A. Cunning- ham, a botanist ; " and also to '^ engage any other person, if there be such in the colony, who possesses a competent know- ledge of Mineralogy or Natural History." If the services of any such person could have been obtained, considerable additions would doubtless have been made to the collections : without this assistance however they are extremely respectable, and, when his numerous other avocations are considered, they may even be " regarded as highly creditable to the zeal and exertions of Capt. King. British Entomology ; or Illustrations and Descriptions of the Genera oj Insects found in Great Britain and Ireland, By John Curtis, F,L,S, Nos. xxii — xxiv. The first of the numbers which we have now to notice exhibits 1. Lebia turcica^si species exceedingly rare in Britain. 2. Cleora cinctaria^ a species new to this country, and associated under the above generic name with the Geometra abietaria^ G. crepuscularia^ &c. 3. Abia nigricornis 3' and $ . 4. Chironomus cestivus, a new species of this very extensive genus of Diptera nearly allied to the C. elegans of Meigen. In the twenty-third number are contained 1. Obrium ca«- iharinum ^ and $ ; the former sex having been described by Fabricius and Panzer under the name of Saperda brunnea, and the female by that of S. ferruginea. The name of the genus has been adopted from Megerle, but his characters, if indeed they have been published, have not yet reached this country. It differs chiefly in its long and dilated, or subspinose, thorax from Saperda and Callidium, and is also peculiarly distinguished by the length of the first joint of the antennae. 2. Spilosoma. Walkerii^ a non- descript species of a new genus allied to Eyprepia^ and compre- hending Bombyoc lubricipeda^ B, menthastri, &c. which are readily distinguished by their spotted bodies. 3. Clavellaria marginata^ Tenthredo marginata of Liime, which Mr. Curtis sus- pects to be merely the female of the Amerinw of the same dis- 140 Anali/tical Notices of Books, tiiiguished author. 4. Laphria nigra^ the only species of this numerous genus of Diptera which has yet been detected in Eng- land, where it is by no means common. The twenty-fourth number comprises 1. Hydaticus cinereus^ recently captured for the first time in this country by Messrs. Chant and Bentley. It is the Dytiscus cinereus of Linne, but not of Fabricius nor of Marsham. 2. Vanessa Antiope^ with its larva, 3. Zarcea fasdata of Leach. 4. Merodon clavipes^ of which only two specimens have been taken in England. An additional leaf is given in the last number for the purpose of being substituted for that containing the description of Acilius cinereus^ the insect previously figured under this name being in fact a new species, to uhich Mr. Curtis has found it necessary to assign the name A, caliginosus. In concluding our notices of the second volume of this import- ant addition to our entomological libraries, we need only refer to our previously expressed opinions of the value of the work, and of the beauty and accuracy of the figures contained in it, and repeat our cordial wishes for its continuance in the same excellent style as that in which it has commenced. A third volume has since been completed, to which we shall advert in our next number. Histoire Naturelle des Mammiferes^ avec des Figures originates^ dessinees d'apres des Animaux vivans; S^c.

The most striking feature exhibited by them is the dismemberment of the genus Elephas, for the purpose of esta- blishing a new one under the name of Loxodonta. It is some- what singular that notwithstanding the very striking difference in form between the African and the Asiatic Elephants they should have been confounded together by Linne under the deno- mination of Elephas maximus, M.

Capensis, while to the latter was assigned that of E. Indicus. M. F. Cuvier has now advanced still farther, and has regarded them as the types of two genera, differing from each other as much as Canis from Hycena^ or Lagomys from Lepus, For the Elephant of Asia he retains the original generic name Elephas, The surfaces of its molar teeth present fasciae of enamel irregularly festooned ; while in those of the African Elephant, the type of the new genus Loxodonta, the enamel is disposed in lozenges. In addition to this striking distinction de- rived from the dentary system, M. F. Cuvier also enumerates the other characters which have hitherto been regarded as specific. The smaller, more elongated, and less irregular head of the African animal when compared with the Asiatic : the rounded forehead of the former, strongly contrasted with the deep de- pression in the middle of that of the latter : the ear of the former also twice the extent, while the tail is only half the length, &c. Since 1681 no African Elephant has been seen in Europe until the young female figured by M. Cuvier, which is now alive in Paris, having been sent as a present by the Pacha of Egypt. Its habits, so far as those of a very young animal can be relied on, exhibit none of the ferocity usually ascribed to it, and are.indeed fully as mild, intelligent, and tractable, as those of the Elephant of Asia. The remaining novelties relate only to species. One of these is a new species of Macacus, M. carbonarius, which is closely allied to the M. cynomolgus, (Simia cynomolgos^ and S. cyno^ cephalusy L.) differing from it in fact only in the black, instead of tanned, colour of its face. It is a native of Sumatra. The Beaver of Europe, M. F. Cuvier is now disposed io con- sider as specifically distinguished from that of Canada by the form of its head. Viewed in profile, instead of presenting a nearly uniform curve from the occipital bone to the end of the ossa narium, its outline is almost straight, being inflected only towards its middle; its sagittal and occipital project strongly, the 142 AnalT/tical Notices of Books, zygomatic arch is broad and much depressed, the whole cerebral portion is considerably elongated backwards, and the nasal bones advance far beyond the orbitar process of the os frontis. These parts are strikingly less developed in the American Beaver, which also appears to be one-sixth smaller at the same age than the living European one now in the Jardin du Roi. In their habits there appears to be less to distinguish them than has hitherto been supposed. The European species evinces the same aptitude and ability in constructing a habitation as are exhibited by the Beaver of Canada, anecdotes in proof of which are related by M. F. Cuvier ; nor can our readers fail to recollect the very striking exemplification of this propensity noticed at page 425 of our last volume. In the preceding analysis we have endeavoured to embody the ■whole amount of the new views exhibited by the latest numbers which have reached us of the folio edition of the Histoire Natu- relle des Mammiferes. At the same time we received al"so several of the earlier numbers of the quarto edition of the same work, which has long been promised to the public. Their appearance was at once a source of gratification and of regret ; the former resulting from the greater scientific value and more moderate price of the new edition, and the latter from the indication which it furnishes of the speedy termination of the original work. We had formerly flattered ourselves that it was the intention of the authors to render it, as far as the present state of the science would admit, a complete gallery of Mammiferous Animals, and it was with this impression that we passed over without surprize the numerous figures which they have given of the commonest species, but which ought scarcely to have obtained admittance into such a work, if destined to include only a fraction of the class to which they belong. A work containing three hundred and sixty figures, taken from the living animals, accompanied by minute descriptions, and illustrated by valuable zoological observations, is certainly of the highest importance ; but we cannot avoid feel- ing that its bulk, and, in the same proportion, its cost and the difficulfy of its acquisition, has been greatly increased by the Zoological Proceedings of Societies, 143 needless repetition of figures of animals known to all the world and already represented in various publications with all the accuracy of which art is capable, as well as by the reiterated representations of others in several stages of their growth. It may be however that circumstances beyond the control of the authors have compelled them against their will to limit them- selves to the comparatively small number of species to which their illustrations must now be confined ; and if this be the case we can only express our regret that so grand an undertaking has been thus rendered imperfect, while we tender to them our best thanks for having executed even this portion of it in so superior a manner. In addition to the advantages of a lower price and of a more portable form it is necessary to add that the quarto edition pre- sents also those of a systematic arrangement, and of valuable general articles on the families and genera which are not to be met with in the original work. Art. Xni. Proceedings of Learned Societies on Subjects connected with Zoology, ZOOLOGICAL SOCIETY. In our last number we had the opportunity of congratulating our scientific readers on the approaching establishment of this Society : and we published a short Prospectus explanatory of its views. Since that period the Society has been completely organ- ized ; and its plans and objects are now before the public. The first meeting for the formation of the Society took place at the House of the Horticultural Society on the 29th of April, 1826, when Sir T. Stamford Raffles was unanimously elected President of the Society, and a Council was appointed to assist him in the direction of its affairs. Committees were subsequently appointed for the planning out and superintendence of the several departments ; and considerable progress was made in the preliminary arrangements of the Institution, when the sudden and lamented death of the President deprived the Society of its 144 Zoological Society, founder and chief support. The different Committees however did not relax in their duties ; they continued to forward the plans which had been commenced under the superintendance of the President, and before the end of the year they had completed some of these plans, and had brought the rest to a state of con- siderable forwardness. A house was taken for the accommodation of the Society, situated at No. 33, Bruton Street ; and was fitted up for the exhibition of the different preserved collections of the Society. A plot of ground was also obtained from the Com- missioners of Woods and Forests, &c. in the Regent's Park, for the exhibition of the living collection : it was fenced-in and drained, and prepared, as far as the season would permit, for plantations, walks, &c., with ponds, sheds", aviaries, and other suitable accomodations for the living animals. A second meeting took place on the 7th of March, 1827, for the purpose of electing a President in the place of Sir T. Stamford Raffles, when the Marquis of Lansdown was unanimously chosen to that office. From the report of the Council, which was laid before the meeting, it appears that the Museum of the Society is now open to the Members. It consists of several thousand subjects in every branch of Zoology ; and it forms a well-arranged and instructive collection in almost every department of the science. This collection has been formed, with the exception of one or two trifling purchases, by voluntary contribution; and every day it receives an increase from the zeal and liberality of the Members. It was also reported that the works in the Regent's Park are rapidly advancing : 'and it was expected that the gardens will be opened early in the ensuing summer. The Council and Officers of the Society consist of the following noblemen and gentlemen : — Marquis of Lansdown, President : Duke of Somerset, V.P. ; Earl of Darnley, V.P. ; Earl of Egre- mont, V.P. : Viscount Gage : Lord Auckland, V.P. : Lord Stanley, V.P. : Sir E.

Having only single specimens, I have not been able to examine the trophi of any species of this genus, but probably they are not very different from those of the other Rutelidce; yet the mandibles are less prominent. With regard to external and secondary cha- racters, Cnemida diflfers from the other insects of that family con- siderably. For instance, its front is distinguished by a long fovea ♦ Introd. to Ent. iii. 366. B. t Ibid. 378. B. + Ibid. 368. 1. || 'ibid. 369. B. § Ibid. 369. D. ** Ibid. 379.

When masons prepare the wall of a house for the outward coat of plaister, they draw lines upon it with their trowels, by means of which this coat adheres to the other. So the acuducted parts of the insects I am describing, in this respect differing from the other RutelidcB, afford a surface properly prepared for the adhesion of the above matter. From their agreeing together in their sculpture it is extremely probable that all the species of this genus of the New World collect some farinaceous substance, most likely from the plants that they frequent, for some purpose important to them in their peculiar economy. Were it granular I should at once pronounce It to be pollen, and as the hive-bee knows how to reduce the farina of flowers to a« impalpable powder, before it forms it itito the little masses of paste which it carries in its posterior tibiae, so may the insects in question. Whether the farina thus collected is intended for the food of the insect itself, or its larvaj, can be determined only by actual observation ; but, reasoning from ana- logy, the latter seems the most probable. I had occasion to ob- serve however, * with regard to another of the same family, that the molary part of its mandibles was filled with a similar sub- stance, which makes for the former opinion. These circumstances tend to confirm Mr. W. S. MacLeay^s hypothesis, that the Rute- lidce^ though like the Melolonthidce, &c. furnished with corneous ^andibulae and maxillae,, are anthobiouSj or derive their food from the blossom and not the foliage of the plants.

MacLeay's great Family of CetoniadcB constitutes, I think, a Stirps rather than a Family y and appears to contain at least three larger groups, each resolvable into various others — viz. Trichiadce, Cetoniadce^ and Gymneti- da. The first including Trichius F, Cremastocheilus, &c. ; the second those CetoniadtE without a lobed prothorax; and the third those in which that part is lobed, and covers the scutellum. — '' As Knoch's Neue Beytrdge is not a common book, I have given from him in part the characters of Cremastocheilus.

Latreille appears to have hesitated much as to the natural station of this genus. At first he placed it at the head of his Scarabeides with membranaceous mandibles, immediately before Trichms*, In his Considerations^ &c. J it follows that genus. In the Regne Animal it closes the petalocerous genera +, and is succeeded by Lucanus, Again in the XXXth Volume of the Nouveau Dictionnaire D^Histoire Naturelle^ published two years afterwards, it resumes its former station after Tnc/tm ;|| and lastly, in his Families Naturelles Du Regne Animal^ it forms the second genus in his Family of Melitophilt, being preceded by Plati/genia, which also is remarkable for a large coacsLve labium ^^ and followed by GoUathus.** It appears to form an osculant genus, as well as the preceding one. Its Mandibulce corneous, with the exception of a dorsal lobe of membrane, and its corneous Maacilla armed with spines, prove that it is of that description, and its general habit and characters, that it is nearly related to the Tri- chiadce, and that it connects M. Latreille's Melitophili with some other family in another circle. Cnemida indeed in some respects Beems without the circle of Rutelidce, and may be also regarded as osculant. If we look at the remarkably depressed body oWretnas- tocheilus and its quadrangular prothorax, we find an analogy between it and some of the Scarabceidce M'L. particularly amongst the Onitidce^ where a remarkable genus from South Ame- rica, named by Mr. MacLeay Euiomusy exhibits considerable re- semblance at first sight to it. It has one character in common with the Dynastidm^ which is only to be met with in one other petalocerous genus, as far as ray examination of them goes, the prosternum is nearly vertical, forming a kind of pectoral horn, before the base of the arms, or fore legs.

This species is larger than either of those described in the eighth number of the Journal, and is sufficiently distinguished from them by its channelled prothorax with very prominent angles. The species which I then described as the original C, Castanece* of Knochj and which was sent me under that name from America, upon a comparison with his description and figure, which I have since had an opportunity of consulting, I find to be quite a dis- tinct species. I propose therefore calling it C. Harrisii^ from Dr. T. Harris, who sent it me. Knoch says of his insect, " Tho- rax pr ope basin latissimus,^^ whereas in C. Harrisii the protho- rax is square (Plate V. Fig. 3. tf.) ; in C. Castanece, also the la- bium is wider than long, but in the former it is nearly round. In his the prothorax is covered with puncta, but in mine it is partly levigated. The sculpture of the elytra also differs. C. Castanece approaches much nearer to that which I have called C. variolosusy (Plate V. Fig, 4) but it is larger, the prothorax is wider posteriorly, and the notch of the labium is not near so deep. We have therefore already four species of this remark- able genus, which appears to belong exclusively to North America : at least nothing similar seems to have been found in the vast col- lections of S* American insects that have been sent to this country. * Plate V.

This remarkable genus appears nearly related to the preceding, and makes an approach, in some respects, to those Gymnetidce whose elytra are lobed at the shoulders, yet the prothorax is not porrected behind, so as to cover the scutellum ; it however most resembles those Cetoniadce that are remarkable for their lobed shoulders, and have an uncovered scutellum, such as C. Hisirioy versicolor^ variegata^ &c. but it wants the prominent character of Cetoniadce, the scapular forming a fulcrum between the elytra and prothorax : its place is probably between Cremastocheilus and Genuchus +, which last exhibits the above character, and is more nearly related to the Cetoniada^, Undatus.

It is said by the Baron De Jean, in his catalogue, to be a native of the East Indies. ♦ Jntrod. to Entomlog. iv. 273. n. 47—9. of Petulocerous Insects, 153 Genns. Acanthurus.

I may perhaps render some little service to the Entomologist, if, as a conclusion to this paper, I endeavour to point out the natural groups into which the true genus Trichius, according to my idea of it, and as far as my own collection will enable me, may be resolved. Fabricius, in his Systema Entomologice and Species Insectorum^ took for the type of his new genus Trichius^ which he so named, I suppose, on account of its hairy body, Scarabceus fasdatus of Linne : but in his later works he seems to have considered T. Eremita as his type, which beipg nearly a naked insect, does not so well correspond with the name. I shall consider the former a^ the true type of the genus, which as far as my own collection leads, I find to consist of seven subgenera as follows : Genus. Trichius F. Subgenera. * Legitimi.

Instead of giving the denominations of the subgenera a feminine termination as proposed in the Introduction to Entomology, I have followed the gender of the genus, which appears to me best. Should any of these, upon further examination, appear more than subgenera, it will be easy to alter the name to the singular. Mr. W. S. MacLeay has observed with regard to Trichius faS" ciatus, how much in its general appearance and mode of flight it resembles a wasp or some hymenopterous insect. J This observa- tion may be extended to several other beetles, especially to many of Latreille's Anthobii ; some species of Amphicoma and Aniso- nyx so closely resembling humble-bees as to be scarcely distin- guishable from them, another proof of those remarkable analogies where there is no affinity, that meet us wherever we turn to observe natural objects. As the hairy Hymenoptera are useful in fertilizing flowers, by transporting upon their hirsuties, far and wide, the farina fecundans, so these beetles probably answer the same useful purpose, as has been well remarked by the learned author just named.t Some of these flower-frequenting Petalocera * Linn, Trans, xii. 408. n. 46.

A Description of several new Species of Chitones, found on the Coast of Chili, in 1825 ; with a few remarks on the method of taking and preserving them» Bj/ John Frembly, R.N., Corresp. Memb, ZooL Soc, The difficulty of capturing, and the concealed sittiations in- habited by this interesting genus, is perhaps the principal cause of so small a number of its species being known : with the hopes of adding a few to the catalogue, my attention was principally directed towards thera^ whenever opportunities for collecting offered themselves. Having been so fortunate as to discover some decidedly new species, and others which were but imperfectly known, and of which the descriptions and figures were very incomplete, I have been induced to submit the following details to the public, but with the conviction that my small stock of knowledge in the science is scarcely sufficient to do justice to the subject. The decided and strongly marked characters of the species which I am fortunate enough to bring to notice, render it un- necessary for me to depart from the mode of description generally adopted by Conchologists, in recounting the peculiarities of the individuals of this genus already known. Their habits and eco- nomy, as far as I have been able to inform myself, will be de- tailed at length. The unnatural distortions, and imperfect state of preservation in which the species are generally brought to us, is an evil that Conchologists have long had reason to complain of; and which prompts me to place in this article a description of my mode of taking and preserving these animals, hoping it may aiford to future collectors the advantages 1 have derived from it myself. Some care and dexterity is requisite in taking the animals from the substances to which they attach themselves. On turning a stone (on the underside of which they are generally found), force will not be necessary to detach them, if instead of attempting to tear them directly from the stone, they are geiUly slid off from it : Vol. III. N Idi Mr. Ffembly on some species of Chitones this proceeding is at all times advisable, when it is possible to put it into execution, as by it a specimen may be removed without the assistance of a knife or injury to the margin, which in this genus foi'ms an importJint character, a-s well as adds beauty to the spe- cies; whereas by endeavouring immediately to detach them, con- siderable force is often requisite, and without great care in the use of the knife the margin will suffer by the attempt. The haunts of some of the species will not admit of this mode of capture, especially of those found in the fissures of rocks; these notwithstanding may be taken without mutilation of the margin, by taking care not to touch the animal before the knife is inserted tinder the shell; this being done, if the knife be quickly turned, it will easily remove the specimen : not touching the animal until the moment of capture, is a very necessary precaution in collecting fell the large species, as their adhesion is so strong that they not unfrequently part with a portion of their shells rather than let go their hold : but in a quiescent state, or before they are conscious of danger, their attachment is very slight. The collecting box I have been in the habit of using, was a rectangular one of wood, which I thoroughly wetted on the inside. Immediately after a specimen was taken, its flat surface was ap- plied to the bottom or sides of the box, to which in most cases it adhered, especially if it had been taken from a smooth aiid flat surface : in this position the animals were suffered to die. The space immediately surrounding them soon becoming dry, they mostly remained steady in the place they first attached themselves to. It appears advisable not to let one specimen touch another, as they are apt to crawl over each other when conscious of their proximity. Although this manner of collecting I have found from experience to be the best, yet in many cases it may not be convenient. They should, however, as soon as possible after being conveyed home, be put into a good sized flat vessel, with a little sea water in it ; and if they have not been long taken, or, the animal much injured, they generally expand themselves to their natural positions, and remain adhering to the vessel until life becomes extinct. I have also found in some cases, when circumstances have not allowed me to attend to them presently after collecting, and they have from Chilu Il!5 been suffered to die unheeded, that the contracting muscles have become sufficiently relaxed to allow them to be put into a natural position without injury to the shell, or separating the valves, but this is too uncertain ah occurrence to be depended on. The ani- mal, being dead, is to be extracted from the shell with a sharp pointed knife, beginning at the posterior part, and cutting round on both sides towards the head. J advise this mode of proceeding from the internal structure of the valves being less liable to injury than by cutting promiscuously from head to tail, in which case the knife would cut against the sharp edges of the valves, and cause much damage to them ; but in the former method of operating the knife only passes over them in the direction in which they lie, consequently not with so much danger of detriment to the shell as the other. After cleansing the shell it should be laid on a flat board, with the margin spread in the same manner in which it was observed to be before the specimen was taken, and to prevent the ends of the shells being brought towards one another by the con- traction of the muscles in drying, another flat board should be placed over them, with a weight proportionate to the size of the shells ; they should be allowed to dry very gradually, and it will be necessary to pay some little attention to them while drying, in order that the edges of the margins may not become shrivelled up by drying sooner than the other part. Following the example of the writer of the interesting paper on the British Chitones, which appeared in the 5th number of this work, I have divided the genus into sections, corresponding with the character of the margin, the propriety of which arrangement appears to be too evident to meet with any opposition. It is perhaps worthy of remark, that out of more than 500 spe- cimens, not one occurred with only seven perfect valves ; but in a few instances I have found them with one of the valves imperfectly formed, which, on a slight inspection, might be overlooked, being nearly, or wholly, covered by its neighbours. These malfor- mations, I have no doubt in my own mind, proceed from accident during the early period of the animal's existence. It may be answered that these, as well as others of this class, have the power of replacing any injury they may receive in their covering during X 2 196 Mr. Frembly on some species of Chitones their young state, but this reproduction is very partial in this tribe ; nor do I suppose that when a valve has been so materially injured as to lose its power of restraint on the contracting muscles, that it can retain its situation, but must be quickly displaced or concealed by the valves next in succession closing up the gap. Accidents of this kind, I am inclined to think, have occurred to those species, which are described as having only seven valves 5 and it would be an advantage to the science if the possessors of the seven valved species would take the trouble to give them a minute investigation, as much valuable information may be elicited, and a subject on which much doubt at present exists might be decided. I must not, however, conclude these remarks without acknow- ledging the assistance I have received from Mr. G. B. Sowerby, without which I should hardly have ventured to intrude on the public notice. * LIGAMENTO MARGINIS SPINOSO. 1. Chiton spiniferus. C. testa oblongo-ovata, ligament© marginali lato, spinifero, spinis longiusculis ; valva antica radiatim granosa ; areis centralibus valvarum posticarum longitudinaliter concinne sulcatis, late- raiibus rotundatis, radiatim granosis.

Shell opaque, oblong ovate, reddish brown, glossy ; inside red- dish white: valves eight, the posterior angles of which do not cover the anterior ones. Anterior valve with generally nine rows of raised dots diverging from the apex, but the number perhaps varies with the age of the shell. Second valve rather acutely beaked and carinated, longer than the five following, which are striated and shaped alike ; these all rise into rather an acute beak, are carinated, each side of the carina divided into two distinct portions, the anterior one the largest, and bearing broad irregular from Chili. 197 longitudinal striae; a prominent row of raised dots extending from the apex to the anterior angles of the valves separates the com- partments; the posterior portion glossy, with fine concentric striae : the posterior margins with tooth-like granulations. Last valve striated like the anterior compartments of the others, and rising into rather a prominent beak, leaning towards the posterior margin : from under the beak are raised dots, disposed in a simi- lar manner to those on the anterior valve. Border coriaceous, thick, broad, rough, greenish or orange coloured, and in the younger specimens thickly studded with blunt spines, but in the old shells the spines are short and scanty, and generally covered with corallines; the inner edge of the border inserting itself under the posterior angles of the valves, has the appearance of being deeply serrated. We -havo found this species five inches in length, and nearly three in breadth. These inhabit the rocks on the coast of Chili ; at Valparaiso we found several specimens in very exposed situations, so much so that collecting. them was attended with much difficulty, and not unfrequently with danger, from the violence of the sea breaking ■on the rocks, to which they attach themselves very strongly. They are generally covered with short sea weed. We have been obliged to alter the name a second time, because the name aculeatus given to it by Barnes, was long since pre- viously occupied ; that of tubercuUferus was given from an ol,d specimen, in which the spines were reduced in length by being broken, so that it is not applicable i we have therefore now called it spiniferus. ** LIGAMENTO MAllGINIS SQUAMOSO. 2.

Border thick, moderately broad, and covered with coarse seed-like scales, which are attached laterally. Length three inches, breadth one and a half. The only part of the coast on which we have found this new spe- cies, tvas the south side of Coquimbo Bay : hence its specific designation. The beaks of the large specimens are generally very much eroded, and covered with Patellas, Balani and corallines, but the young shells are often quite perfect ; from one of these I have drawn the above description. I am aware there may be objections to giving the characters of young shells for the identi- fication of species, but in this case an old shell so rarely occurs in even a moderately perfect state, that its characters could scarce have been detailed from such a specimen. The habits of this species are very similar to those of C. spini- feruSj with the exception that they seem to be more grega- rious. *** LIGAMENTO MARGINIS GRANULOSO. 3. Chiton Cumingsii.

Length two inches, breadth 1^% ; found plentifully at Valpa- raiso under stones in still water, A variety of this species occurred,^ differing ii^ these respects from the above description. Shell thicker, back more raised, and the posterior compartments of the dorsal va|ves less distinct. A specimen also was found shewing oa the outside oply seven valves, but inside the articulation of the other valve was plainly seen. I have named this species after my friend Mr. Cumings, of Valparaiso, whose zeal in the pursuit of this interesting science will, I am persuaded, sopn make a large addition to our present stock, 4. Chiton oUvaceus. C. testa ovali, lata, olivacea, aeruginoso-punctuiata; valvA antica posticaque radiatira-striatis ; areis valvarum centrajibus longii- tudinaliter sulcatis, lateralibus radiatim striatis. Tab.

Valves eight, the anterior one with regular radiating striae, crossed by concentric ridges j pos- terior margin nearly straight. Dorsal valves obtusely beaked, divided laterally into two compartments ; the anterior having re- gular longitudinal striae, crossed vvith others v^ry minute and con- centric; from under the beaks diverge to the lateral margins of the valves coarser and more irregular stria?, which raise the pos- terior compartment above the other. The posterior valve has 9- well defined apex, leaning towards the posterior margin. Border thin, moderately broad, and covered with fine shining bead-like granulations, of the same colour as the shells, divided into two distinct portions, the upper of which is composed of much finer beads than the lower, and which, as in the last species, are placed trans^versely. 200 Mr. Frembly on some species of Chit ones This species grows to a large size ; one in my possession mea- sured when alive upwards of four inches in length ; but the ge- neral size is about three inches. We have observed amongst these a variety much narrower than the generality of thenij but not differing in any other respect from the above description. This is not given here as a new species, a specimen from the Tankerville Collection, now in the possession of the Rev. Dr. Goodall, agreeing so nearly with mine, that there can be no doubt but they are of the same species. It has, I understand, been called C. latus^ but that term would not be applicable to both varieties. I have therefore taken the liberty of naming it from its colour, to which I am aware there are many objections, nor would it have been adopted but from the unvarying hue I have observed to run through the whole of the specimens which haves passed under my notice. Amongst the very young shells, I observe that some of them have their borders of a lighter colour than their shells, and spotted with black ; this not being a constant character in all the young specimens, they may be regarded as a variety. 5.

This new species is found plentifully at Valparaiso in the fissures of the rocks, but generally put of the reach of the breakers : the habits of this species are yery different from those of the others which have come under my observation : like many Patellce they are soinetimes at such a dis- tance from the water as would lead one to suppose that they pass Bome considerable part of their existence apart from it. p.

Le travail de M. Horsfield sera d'autant plus important qu^ayant eleve presque tous les lepidopteres, la connaissance parfaite qu'il a de leurs larves le mettera a meme de relever nombre d'erreurs commises dans leur classification jusqu'a ce jour, par I'ignorance entiere ou I'on etait a ce sujet, et de nous donner une histoire complete de ces insectes, qui nous manque, et que I'on attend avec impatience de la plume de cet habile observateur. Les caracteres generiques des Lepidopteres, surtout dans les nocturnes, presentent trop de dissemblance avec les notres pour que M. Horsfield puisse les faire tous entrer dans les sections qui existent. De nouvelles coupes, de nouveaux genres peut-etre^ sont a n'en pas douter necessaires a etablir. Comme ce n'est pas a moi qu'il appartient d'en juger et de les faire connoitre,je me suis contente pour ces cinq especes d'indiquer la place qu'elles doivent le plus naturellement occuper en ce moment ; jusqu'a ce que les Entomologistes dont s' honorent les Societes Linneenne et Zoo- logique de Londres ayent fait connaitre les genres auxquels elles doivent definitivement appartenir. 18 Ma/, 1827. des Indes Orient ales, $0^ GASTROPACHA VISHNOU.

Egypt, Geoffroij^ This species, which is evidently the one originally described by Linnaeus, is known by the peculiar pyramidical form of the occiput, by the single large irregular quadrangular flat space on the cheek, (which is double in C, pumila)^ and by the slightly crested denticulated white line from the chin to the vent. The teeth are rarely (as they are described to be by Cuvier) slightly 3-lobed, which is an anomaly in those Lizards which have them placed on the edge of the jaw. When the animal is alive and in health, the angles of the occipital pyramid and the lines on the side of the face are completely obliterated. It is distinguished from a spe- cies from Central Africa, by the occipital keel extending to the centre of the eye, by the back of the head being only slightly lobed^ and by the frontal scales being tubercular.

This geniis can be confounded only with the Uroplates of Daudin, from which it may immediately be distinguished by the toes being completely webbed, by the scales of their under side being broader towards the extremities, and entire, and by the last joint, which bears the claw, being raised up and exposed, while in the Uroplates it is inclosed in the groove of the scales, and com- pletely hid from view ; indeed the formation of the toes is similar to that of the Platydactyles and Geckos^ but it differs from them in their being webbed, and in the membranes on the sides of the body, which appear to indicate very different habits. 1.

The tail, which is round at the base and slightly com- pressed at the extremity, is covered with small irregular flat scales, and is narrowed at equal distances into 16 — 18 ring-like con- tractions, which are more visible in the centre, and gradually dis- appear at each end. Each of these bands is furnished with a series of large orbicular subcohical scales on the edge. The labial scales, especially of the upp6r lip, are very long and narrow. The edge of the eye-lid is reflexed and expanded ; femoral pores 8 — 9 on each side, in a triangular series; toes very short.

This genus belongs to that group of the family which differs from the type in the toes being destitute of those scales on the underside which enable them to climb on perpendicular surfaces; but it is known from the other genera of this section by the peculiar form of the toes, which are arched at the end, that is to say, the third joint is very short, and forms a right angle with the second ; the fourth then goes off horizontally from it, and the joint bearing the claw is bent down at the end, so as to give the foot a very peculiar appearance. 1.

There is a drawing of a Scinc^ supposed by the natives to be the young of this species, which is pale golden green above and yellow beneath, with a pale whitish border and scattered black spots on each side, just over the legs. 2. T. trivittata. n. s. Supra pallide brunnea ; dorso fasciis tlavis tribus latis nigro- marginatis; lateribus pallidis maculis nigris rat is; subtus albida. Inhabits gardens, Dumdum. Length, 8-^ ; liody, 4j ; Tail, 4 inches. Above pale yellowish-brown, witli three broad yellow bands on the back edged with black ; the bands are two series of scales broad, and have two series of scales between each of them, the yel- low situated on the two inner halves of the two series, and the black occupying the other outer halves of the scales ; sides paler, with a few black spots ; beneath v, hitish ; under the eye a black streak. The tail banded like the back, very nearly as long as the body; ears denticulated in front ; toes rather short. From a draw- ing. p 2 228 Gen.

Body long, cylindrical. Tail long, cylindrical, slightly attenu- ated; equally covered with imbricate scales. Legs 4. rather short. Toes 5. 5. unequal, clawed. Head shielded. Tympanum of the ears sunk, but distinct. Head with one rostral, one anterior and one posterior frontal, a large anterior and a small triangular posterior vertebral, and two oval occipital shields. The animals of this genus are separated from the Seines by the cylindrical form of their body and tail, and the shortness and weakness of their legs. They agree with them in the scales, num- ber of toes, and in having a visible tympanum, which separates them from the Anguis quadrupes of Linnaeus. They are separated from Seps by the form and number of their toes. 1. Li. serpens.
