THE GUENONS.

wllli a black, the other with a white band over the eyes. They are not 
so capricious as the otiier Guenons. The damage occasioned l)y tliese 
animals in the cultivated fields of Senegal, at the seasons when the millet 
and other grain become ripe, is incalculable. Forty or fifty Guenons 
assemble together. One Guenon mounts upon a tree as an outpost, 
listening and watching on every side, while the remainder are plundering. 
As soon as he perceives any one aiiproaching, the sentinel cries out like 
an enraged person to give notice to the remainder, who start oft with their 
booty on hearing the signal, and leap with prodigious agility from tree to 
tree. The females, who carry their young clinging against the abdomen, 
run off* with the rest, with the same agility as if they had tio burthen to 
carry. These animals do not agitate their jaws, when di.spleased, like the 
other Guenons and they walk more frequently upon all the four hands 
than on two only. They are from a foot and a half to two feet in length 
from the point of the muzzle to the insertion of the tail; and the tail is 
not so long as the body and head taken together. 
The body is slender. The head medium size; with the cranium slightly 
lengthened and flattened upon the vertex; the forehead projeciing abovelhe 
orhits of the eyes, and above the upper [tart of the nose. The fiice is flesh- 
coloured, the nose covered with short black hair; the eyes sunken; a 
black or white band passing over the eye, resembling a prolonged eye- 
brow ; the hair very plentiful upon the cheeks, forming cheek-tufts ; the 
ears naked. Its bright yellowish-red hair, which extends over the fore- 
head, the vertex, occiput, upper part of the neck, the back, sides, crup- 
per, sometimes only the tipper part of the tail, and sometimes the whole 
tail, and the thigh, arc not without some mixture of hlack and grey, pro- 
ceeding from the circumstance that many oi the hairs are black on the 
points and elsewhere grey, The red hair becomes paler upon the outside 
of the arm, the fore-arm and leg ; while it finally tend.s, upon the cheeks, tip 
of the muzzle, neck, lower part of the neck, arm-pits, the inner surfaces 
of all the limbs, the breast and the belly, to a white, mixed in several 
points with yellow, pale-red, and grey. The hair throughout is general- 
ly rough and glossy. The nails are black, the palms of the hands brown. 
Mr Bennett remarks, that a specimen in the Gardens of the Zoological 
Society of London was “ lively and active, hut somewhat irascible if dis- 
turbed or bandied. It was, how’ever, too young to be dangerous. When 
pleased it danced on all-fours in a peculiar and measured step, which was 
far from being ungraceful ; although after a time it became ludicrous from 
its regular monotony."

Inhabits the Western coast of Africa. 
Ruffon says that tins animal comes from Madagascar, while Has- 
selquist assigns it to Abyssinia. The fact is, as we are assured by 
Sonnerat, there are no Apes at alt in Madagascar. 
It possesses so many intimate relations to the following species, (3) 
dtat Buffbii and Pennant confounded them together under the common 
names of Mangabey and Wliite Eyelid Monkey. Yet their differences, 
slight as these may be con.sidcred by some, are found to be so invariably 
same in numerous individuals, that we cannot hesitate to pronounce 
them distinct species. Their variations, it will be remarked, are chiefly 
In the colours of the head and neck. 
The height of the Collared Mangabey Guenon is about a foot and a 
half, being rather less than that of the species next to be described. Its 
hair is very long and soft to the toiieli. The first incisor of the upper jaw 
being very broad, renders its grin at once obvious and peculiar. It may 
he readily distinguished from the otlier White-eyelid Monkey by the 
htight chestnut-brown on the upper surface of its head, and the collar of 
pure white crossing the fore-part of its neck, and including the large bushy 
nheek-tufts, which extend backwards, beneath and behind the ears.

SFECIFIC CHARACTERS. 
The Hair uniform slate-grey above ; whitish beneath ; black on the 
backs of the bands. 
The Eye-lids white. The Ears violet-grey. 
Inhabits Congo and the Gold Coast. 
P.uffon thought that this animal came from Madagascar, and be- 
lieved it to be a variety of the preceding. 
Though one of the most common species of Guenons, it vvas a long 
time before its native country was indicated with precision. Continually 
in motion, it exhibits in captivity the most grotesque attitudes. The 
males arc chiefly remarkable for tlieir agility, and enliven tlieir motions 
by a singular grin approaching to a laugh, at the sanie time showing their 
incisors, which are always very large. They are constantly in the habit 
of holding the tail turned forwards upon the back, and not elevated in 
a semicircular form, as in most of the other Guenons. The length 
from the muzzle to the insertion of the tail is about two feet; the height 
from the shoulders to the palm about IJ feet. The .fimiales are u-sually 
more tranquil, and fonder of caresses than the males. “ A I’epoque 
dll rut, c’fst-a-dire chaqiie mois, ellcs fiproiivent aux parties genitales un 
goiiflement considerable, qui, prfis de I’anus est tres-largo, et qui, a|ires 
s’etre retreci toul-a-coup, descend vers la vulve et I’entoure. Alors on 
volt paraitte uno veritable menstruation.” 
When in captivity, their docility is con.siderahle. Audebert notices 
one individual which danced on the tight rope, holding a balance-pole in 
its hands; took up a book, placed it on a table, and turned over the 
leaves with much ease, mak'ng grimaces at it as though it contained some 
provoking intelligence. The same writer significantly remarks, “ On 
sent que le fouet du maitre jouoit ici un grand role.” 
The muzzle is thick and projecting; the circle round the eyes promi- 
nent. The face varies in colour, sometimes heiug of a deep flesh-co- 
loured tint; sometimes blackish on the fore part of the muzzle, and the 
remainder copper-coloured. Above the eyelids there is coiistaiuly a 
white band in the form of a crescent, very striking ; there are coarse hairs 
on each side of tlie nose, and others stifl'and bristly on the lower part of 
the forehead just above the nose. The ears are naked, violet-coloured, 
without margin, and slightly folded back at their extremities. The hairs 
of the cheek-liifts are directed backwards, whitish, with a grey band. 
The liair of the entire upper part of the body as well as of the tail is a 
slate-grey, with a slight tinge of yellow upon the head; that of the 
throat, breast, belly, and the interior of the limbs, of a greyish-white. 
The extremities of tlie limbs, from the fore-arm in front, tiiid from the 
heel behind, are of a deep black. The tips of the fingers are very thick, 
especially of the thumb ; and the nails are flat.
