Mr. Waterhouse exhibited a new species, from the Society's Col- lection, of Gerbillus, and a new Herpestes, which were accompanied with the following descriptions. Herpestes fusca. Herp.fusca ; pilis nigro flavoque annulatis, ad basin fuscescentibus ; guldfusco-flavd; caudd, quoad longitudinem, corpus fere aquante, pilis longissimis obsitd. unc. lin.

" This species is about equal in size to the Herpestes major or urinatrix of the Cape, and hence is larger than any of the Indian species hitherto described. It approaches in colour nearest to Herp. brachiurus of Mr. Gray, but may be distinguished by its very long and bushy tail. The claws of the fore feet are remarkably large and of a brown colour; the longest claw measures upwards of three quarters of an inch ; the feet are blackish. Each hair of the back is grayish brown at the base, then pale brown, and the apical half is Zoological Society. 467 black, generally with about three or four yellowish rings. At a little distance the animal appears to be of a deep brown colour. " The skins from which the above description was taken were purchased at a sale of zoological subjects, the greater portion of which were from Madras. As, however, there were some from the Nilgherries, it is possible these specimens may have come from that quarter. Gerbillus Cuvieri.

(No. 473. in Catal. of the Mammalia in the Zoolo- gical Society's Museum.) " General colour very bright cinnamon yellow ; the hairs of the upper parts of the body gray at the base ; cheeks whitish, a white spot above, and extending behind the eye ; the feet and the whole of the under parts of the animal white; the hairs of the same colour at the base as at the apex-, tail brownish above, dirty- white be- neath, the apical third furnished with long blackish hairs ; ears blackish, sparingly clothed with white hairs ; hairs of the moustaches black, some of those nearest the mouth white. " This species of Gerbillus, which I have great pleasure in naming after M. F. Cuvier, who has published so excellent a monograph on the group to which it belongs, I have reason to believe has long been confounded with the animal described by Major- General Hardwicke, in the eighth volume of the Linnean Transactions, under the name of Dlpus Indicus. The chief character which induces me to consider it as a distinct species, consists in the comparatively great length of the tarsus. In a specimen of Gerb. Indicus, which exceeds the present animal in size, I find the tarsus to be only 1 inch and 6 lines in length ; and in a specimen in the Paris Museum the foot was only a quarter of a line longer, this animal being likewise larger than the specimen which furnished the above description. In the same mu- seum there is also a specimen of the present species, in which the tarsus measured 1 inch 9 lin. ; the length of the animal being 7 inches 10 lin. In the specimen of Gerb. Indicus, and that of Gerb. Cuvieri, belonging to the Zoological Society's Museum, there is a consider- able difference in the colouring, the latter being paler, and of a much 468 Zoological Society. brighter hue than the former ; but whether this difference is constant I am not aware." May 8, 1838.— The Earl of Sheffield in the Chair. Mr. Waterhouse brought before the notice of the Meeting an ex- tremely interesting series of skins of Mammalia, which had recently been given to the Society's Museum by George Knapp, Esq., who had received them from the Island of Fernando Po. The collection included the following seven species, which were considered by Mr. Waterhouse as hitherto undescribed ; namely, two new Colobi, form- ing a most important addition to that group of Quadrumana of which our knowledge is so extremely limited, from the small number of skins brought to Europe ; two new species of Cercopithecus ; a new An- telope, a new Otter, and a new species of the genus Genetta. These were severally named by Mr. Waterhouse, and the follow- ing descriptions and specific characters communicated. Colobus Pennantii. Col. supra nigrescens, ad latera fulvescenti- rufus ; subtus flavescens ; cauda fusco-nigricante ; genis albis. Longitudo capitis corporisque, 27 unc. ; cauda, 29 unc. Hab. Fernando Po. " The prevailing colour is bright rusty-red ; the head, back of the neck, and the central portion of the back, are black ; the cheeks and throat are white or dirty white ; chest, fore part of the shoulders, the under parts of body and inner side of the limbs are dirty yellow ; inner side of the thighs whitish ; the hairs of the tail are brownish black. The fur is long and not very glossy; that on the head and fore parts of the body being the longest. There is no soft under fur ; the hairs are of an uniform colour to the base, or at least in a very slight degree paler at that part. The portion of the back which is described as black partakes slightly of the rusty hue which prevails over the other parts of the body ; it occupies but a narrow portion of the back, and blends indistinctly into the rust colour. The lower parts of the limbs are removed, bursas they are black at the knee, and also assume a deep hue below the elbow, it is probable the re- maining portions are black externally ; but internally, as far as can be seen, the limbs are yellowish or yellow- white. " There was scarcely any perceptible difference in the colouring in all the specimens examined by me, from Fernando Po, amounting to about eight in number. They invariably had white or dirty-white cheeks and throat. " This species is the nearest yet found to the Bay Monkey of Pen- nant, but differs in having the throat and cheeks white, and in ha- Zoological Society. 469 ving three distinct shades of colour on the body ; Pennant's animal having the cheeks of a pale bay colour, and the body deep bay above, and pale bay beneath. It might be argued that by 'deep bay' Pennant meant to designate the peculiar colour described by me as black with a rusty hue : if so, he could scarcely apply the term ' very bright bay ' to the parts which I call yellow. If, however, even this were the case, there is still another distinct tint which he has not mentioned, and that is the bright rusty-red colour of the sides of the body and limbs. On the whole, therefore, I think I am right in ap- plying a name to the animal here described, which it must be remem- bered is from a different locality; that of the Bay Monkey being Sierra Leone. There is another circumstance which should lead us to be cautious in pronouncing any species which differs as much as that here described, as identical with Pennant's animal, since it so happens that each red Colobus discovered has in its turn been re- ferred to the Bay Monkey, or to the Simla ferruginea of Shaw, which is the same animal, and has had one or both of these names applied, but has been changed upon the discovery of the next species ; in consequence of which much confusion has arisen. I think we had better let the Bay Monkey stand until we can find an animal agree- ing with Pennant's description, Colobus Satanas. Col. niger ; vellere longissimo. Longitudo capitis corporisque, 31 unc. ; caudte, 36 unc. Hob. Fernando Po. " Of this species I have seen three skins from the same locality; one of these was very imperfect ; the other two were perfect, with the exception of the hands and feet. Its uniform black colour will at once distinguish it either from Colobus leucomeros, or Col. ursinus, the former having white thighs and a white throat, and the latter having a white tail, and long grey hairs interspersed with the black on the neck. The longest hairs on the back measure ten inches. The fur is but slightly glossy, and the hairs are of an uniform colour to the base. There is no under fur. Cercopithecus Martini. Cere, pilis corporis supra ntgro et jlavescenti-albo annularis; capite supra, brachiis cauddque ni- grescentibus ; gala abdomineque griseo-fuscescentibus. Longitudo capitis corporisque, 22 unc. ; caudce, 26 unc. Hab. Fernando Po. "Of this animal I have seen but two skins : both very nearly agree in colouring but differ slightly in size ; the dimensions are from the larger specimen. The face, hands, and feet, are unfortunately 4 JO Zoological Society. wanting. It appears to be most nearly allied to Col. nictitans ; the hairs of the upper parts of the body, however, are more distinctly annulated, and the general tint is somewhat greyish. Each hair is grey at the base, and has the apical portion black, with, generally, three yellowish-white rings. The crown of the head and the fore legs are black ; the hind legs are blackish, the hairs being but ob- scurely annulated. The throat is dirty white, the belly and inner side of the legs at the base are of a brownish colour. The tail is black above, and somewhat grizzled at the sides. At the base of the tail beneath there are some deep reddish-brown hairs. The naked cal- losities are small. The hairs on the fore part of the crown of the head are black, annulated with brownish-white, and so are those on the side of the face immediately below the ear. The fur is tole- rably long, and but loosely applied to the body. In the smaller specimen the under parts of the body are somewhat paler than those in the larger, being brownish-grey. '.' I have named this species after my fellow curator Mr. Martin. Cercopithecus erythrotis. Cere, griseus ; pilis corporis supra Jlavo nigroque annularis; guld genisque albis ; brachiis ni- grescentibus ; caudd splendide rufd, lined nigrescente per par- tem superiorem excurrente, apice nigrescente ; regione anali auribusque rufis. Longitudo capitis co?porisque, 17 unc. ; cauda, 23 unc. Hab. Fernando Po. " This beautiful little species is about the same size as the Mou- stache Monkey {Cere, cephus), and has undoubtedly a close affinity to that animal ; it may, however, be distinguished by the bright rusty- red hairs which cover the ears internally, its brilliant red tail, and by the hairs in the region of the anus being also of a bright red. " The hairs on the upper parts of the body are black annulated with yellow ; on the hinder part of the back the yellow assumes a deep golden hue, but, unlike the Moustache Monkey, the black pre- vails over the yellow. On the sides of the body and the outer side of the hinder legs, the hairs are greyish ; and on the belly and inner side of the limbs, they are greyish- white. The fore legs are blackish externally ; a dark mark extends backwards from the eye to the ear ; below this, on the cheeks, there is a tuft of white hairs, beneath which the hairs are grizzled black and yellow, — in these respects bearing a close resemblance to the Moustache Monkey. The face is imperfect, and the feet have been removed from the skin ; these parts, therefore, cannot be described. Zoological Society. 471 Genetta Poensis. Gen. fulvescenti-fusca; dorso lineis nigris eonjluentibus et irregularibus notato ; lateribus maculis nigris crebre adspersis ; caudd nigra, annulis fulvis interruptis.

Geoff., but is distinguished from all the African species with which T am acquainted, by its deep rich yellow-brown colouring, and by the great number of dark markings and spots with which its body is adorned. " On the back of the neck there are three or four slender longitu- dinal black lines, which are irregular and indistinct, especially near the head. On each side of these slender lines there is a broad, ir- regular black mark, which commencing behind the ear runs back- wards and outwards over the shoulders ; here the slender black lines appear to divide, for as many as seven can be traced ; the outer- most of these diverge, and are soon broken into irregular spots, which are scattered over the sides of the body. The intermediate lines are also broken into oblong spots, excepting that line which runs along the spine of the back, which is uninterrupted, and be- comes broader on the middle of the back. On the hinder half of the back there are, on each side of and parallel with the spinal black mark, two lines formed by confluent spots. The sides of the neck are adorned with numerous oblong spots. The muzzle is black; there is a slender black line between the eyes, a yellow spot below the anterior angle of each eye ; the tip of the muzzle is also yellow. The lips are blackish, and the eyes are encircled with black hairs ; the hairs of the moustaches are brown, black and brown. The ears are black at the base externally ; internally they are covered with yellowish hairs. The limbs are brownish-black. The tail is black ; on the basal half there are five narrow yellowish rings, and on the apical half there are about four rings of a brownish colour, and somewhat indistinct. The fur is short, glossy, and adpressed. Lutra Poensis. Lut. nitide fusca ; genis menlo guldque fidves- centibus. Longitudo capitis corporisque, 24 unc. 3 Hn. ; caudce, 13 unc. Hab. Fernando Po. " The only specimen of this Otter which I have seen is smaller than the common European species {Lutra vulgaris) ; its colour is much brighter, being of a rich yellowish-brown ; the sides of the face (immediately below the ears), the sides of the muzzle, and the throat, are of a rich deep golden- yellow with a faint brownish hue. 4 72 Zoological Society. The ears are small, and covered with hairs of the same colour as those on the top of the head. The tip of the muzzle is bare. The moustaches and long bristly hairs on the sides of the face are brown, paler at the base, and blackish at the apex. The tail is about equal to half the whole length of the animal. The fur is short, and the hairs are nearly erect ; the under fur is of a brownish-white colour, glossy silk-like nature, and tolerably abundant. There are no feet to the skin. Antilope Ogilbyi. Ant. splendide fuscescenti-aurata, subtics pal- lidior, lined dorsali nigra ; .collo fusco lavato; caudd brevietjloc- cosd, nigrescente, pilis albis subiiis inter sper sis. Hab. Fernando Po. " The small bushy tail, the character of the fur, which is short and closely adpressed, and the colouring, all indicate in this species, I imagine, an affinity to the Ant. scripta, with which it appears to agree in size. The brown neck, deeper and richer colouring, and the ab- sence of white markings on the body, however, will serve to distin- guish it from that species. As in Ant. scripta, there is a black line along the spine of the back. " The skin from which the above description is taken is without head or limbs. The length from the shoulders to the root of the tail is about two feet eight inches. The tail is about four and a half inches. " If my conjectures regarding the affinities of this animal prove correct, it will belong to the sub- genus Tragelaphus of Hamilton Smith, or to the more extended group to which Mr. Ogilby has ap- plied the name of Calliope. " I have taken the liberty of naming this animal after the author last mentioned, whose careful researches in the Ruminant animals have thrown considerable light on the affinities of the species." Mr. Waterhouse then proceeded to notice two skins which had been just brought from Sierra Leone by Major Henry Dundas Campbell, (late Governor of that Colony,) and sent by him for exhibition at the Society's evening meeting, with a promise on the part of Major Campbell to present them to the Museum, in the event of his being able to make an arrangement with a party to whom he had parted with them as an article of commerce. One of these specimens was a remarkably fine skin of a species of Colobus, described by Mr. Ogilby in the Society's Proceedings under the name of Col. ursinus ; the skin, however, upon which Mr. Ogilby founded his species was imperfect, and until the opportunity afforded by the inspection of the present specimen, nothing was known of the colour of the head and face, which prove to be greyish white. Zoological Society, 473 The other skin was a new species of the genus Cercopithecus, for which the name of Cere. Campbelli was proposed, with the following character. Cercopithecus Campbelli. Cere, vellere perlongo, subsericeo, per dorsum medium diviso ; capite corporeque anteriore grises- centi-olivaceis, pilis nigro Jlavoque annularis; corpore posteriore femoribusque extus intense cineraceis ; guld, abdomine, artubus- que internis albis ; brachiis externe nigris ; caudd pilis nigris et sordide Jlavis indutd, apice nigro, pilisque longioribus instructo.
