SPECIFIC CHARACTERS. 
The Hair greyish or greenish-brown above ; grey beneath ; the upper 
part of the nose black ; the lower white ; a white tuft before each ear. 
The Face covered with black hair ; sometimes naked and violet blue ; 
always flat. 
The Upper Lip with a black raoustachio. 
Inhabits the Coast of Guinea. 
This interesting little animal is one of the smallest and most docile 
species of the genus. It is at once recognised by the white patch on 
its nose, consisting of smooth, short, and closely set hairs. It is lively, 
and active in its manners, and generally good-tempered in its disposition. 
A specimen in the Gardens of the Zoological Society of London was by 
no means familiar, appearing particularly anxious to conceal its face, cry- 
ing out and kicking with all its might when handled for the purpose of 
examination. 
The head is round ; the ears large ; the hair of the forehead and cheeks 
rather short. The top of the head, the upper part of the neck, the back, 
the sides, and the external surfaces of the limbs, are covered with hair of a 
dark brown, sometimes withyellow and grey intermixed; thelips naked and 
brown, covered with scattered hairs; the root of the nose between the 
eyes black ; a white spot upon the nose, formed of very thick and short 
hairs, cut off horizontally on its upper part, and b mlered beneath by 
the nostrils. The under part of the neck and the sides of the head are 
white, sometimes tinged with yellowish, which is prolonged towards the 
breast and belly, where a radd’sh tinge sometimes prevails. The inner 
surfaces of the limbs are of a whitish-grey. The hinder limbs and hands 
are more grey than those before, and without any greenish tinge. The 
tail is of a dirty white beneath, separated by a line from the greenish- 
brown of the upper part ; the anterior hands are black. Its usual length 
is from ten to twelve inches, and that of the tail is usually 15 to 18 inches, 
though it commonly wants some of its vettebr®. 
There is a variety of this species with the face naked and of a bhieish- 
violet, figured by Audebert under the name of 1/ Ascagne.

SPtCIEIC CHARACTERS. 
The Hair black or brown, speckled with white. 
The Nose prominent and white, in the middle of a blueish-black face. 
Inhabits Guinea. 
In respect to its form, proportions, habits, and disposition, this Guenon 
approximates nearly to the Spotted Guenon (10) already described. 
The Winking Guenon is about eighteen inches in length, and the tail 
twenty-eight. The naked parts of the face and ears are blueish-black, 
the ej'elids flesh-coloured, the hands entirely black, and the skin of the 
body white, slightly tinged with black. On the naked parts of the face 
only a few isolated dark hairs are to be seen. But the nose is entirely 
covered with short and thick hair, black between the eyes, and of a fine 
white throughout the rest of its length. The head and upper parts of 
the body, as well as the cheek-tufts, are black, speckled with yellowish 
hairs. The sides are black, speckled with white ; the breast brownish- 
white. The neck, limbs, and tail, arc entirely black, and a black line 
separ.ates the cheek-tufts from the rest of the face. On the lower jaw, 
on the inner surface of the thigh.s and under the arms, the hair is grey. 
These colours are formed for the most part by hairs which are grey at 
their base, and annulated with black and yellow, or black and white through 
the remainder of their length. 
These last five species (9, 10, H, 12, and 13) are small, and 
prettily varied in their coloiir.s. They are very mild in their man- 
ners, and are common in Guinea.

SPECIFIC characters. 
The Hair of the body and cheeks greenish-grey, speckled with black ; 
a wbitish band like a crescent across the fbreliead ; the tail sjieckled with 
white ; elsewhere black. 
Inhabits the Western Coast of Africa. 
This Guenon was figured and described by M. Fred. Cuvier as a variety 
of the C. Diana. It is, however, very different from the Spotted Guenon 
(10), as maybe readily perceived on comparing their descriptions. 
A specimen of this animal lived for many years at the Paris Menagerie. 
On its first arrival, the upper part of the neck, shoulders, arms, fore- 
arms, neck, breast, belly, and tail, were uniformly black, but not of so 
deep a tint as in the lower parts of the body ; the back and sides were 
speckled with black and white, the hairs having small alternate rings of 
black and white. The cheek-tufts were speckled also with black and 
white, and a slight tinge of yellow might be remarked in the white band, 
sliaped like an inverted crescent upon the forehead, just above the eyes. 
Yellow hairs could be discovered only under the callosities, and very few 
iu number. The entire face was of a violet colour, of which the blue 
predominated upon the checks, while the red seemed concentrated upon 
the muzzle and eyelids. The hands were entirely black, and the eyes of 
a brownish-yellow. In the course of a few years, the general distribution 
of these colours did not change, but the white rings of the hairs on the 
back became yellow, and this colour had increased upon the clieek-tufts. 
The hair which covered the internal surface of the thighs became varied 
with grey and white rings, which gave tliese parts a mild grey appear, 
ance, aud the hairs of the tail were covered with similar rings, but the 
grey bad almost become black. The entire coat of tlie animal was very 
thick on the upper part, aud thin beneath, where the skin, as well as on 
the remainder of the body, had a violet tinge.

Sl’ECIFIC characters. 
The Hair bright red above ; white beneath, and on the outside of the 
limbs. 
The Face entirely black. 
T'he Scrotum bright green. 
Inhabits Abyssinia. 
This new species w.tj recently discovered fay M. Elirenberg in Abys- 
sinia, and brought to the Royal Prussian Menagerie, near Potsdam. It 
is known to the inhabitants of Darl'oor by the name of Nisnas, and has 
many relations to the Red Guenon. It appears, however, to be more 
robust, its muzzle is broader aud more obtuse, the tail longer, and the 
face entirely black, while the Red Guenon (1) is black only on the nose. 
It is of a fine brick-red colour upon the body, on the arms, the anterior 
part of the thighs, and on the tail. This hue becomes feeble, and passes 
into a straw-colour on the occiput ; the forehead is rather of a deeper red 
than the back ; the cheeks white ; the naked portion of the face is black- 
ish ; the fore-arms, legs, and the hinder parts of the thighs, of a pure 
white ; the palms of all the hands black. 
DOUBTFUL SPECIES. 
1. C. BABBATUS of Clusius, Exot. p. 371, described by Linn. (Syst. 
Nat. I. p. 3C), is an obscure species, by some referred to C. Diana. R 
is merely said to be black and brown above, white beneath, the beard 
white and ending in n point ; the tail ending in a tuft. 
2. C. HiRCiNA Shaw, Gen. Zool. 1. p. 58. This is the Goat Mon- 
key of Pennant, Quadr. p 212, described with a blue naked face ribbed 
obliquely, a long beard like that of a Goat ; the whole body ond limbs 
deep brown ; the tail long, from a specimen said to be in the British 
Museum. 
3. C. JoHNii Fisch. Syn. Mam. p- 25. The hair of a sinning bleek, 
and bristly, the head greyish-brown. The hairs of the head very spinous, 
giving the animal a peculiar aspect. It is said to come from 1 ellicherj, 
iu the East Indies. (,Iohn. Beschreib. einger Affenarten in Neuen Schrd-
