The Haib greenish-grey above, passing to bright yellow on the loins 
and thighs ; whitish beneath. 
The Face flesh-coloured. 
Inhabits Bengal. 
The Rhesus Macacos frequent the forests on the banks of the Ganges 
in large numbers. Encouraged by the reluctance of the Hindoos to de- 
stroy animals, they carry their depredations to the very suburbs of the 
cities. Their disposition appears mpst untractable. During extreme 
youth, a certain degree of familiarity may be encouraged with impunity; 
but they soon become mischievous, and age renders tliem ferocious. 
Their ferocity is the more dangerous from its being combined with con- 
siderable foresight and intelligence. 
All the upper parts of the body are of a fine greenish-grey, resulting 
from hairs which are entirely grey at their base and throughout great part 
of their length, while their points are either black or yellow. This yellow 
becomes paler on the arms and legs, so as to render these parts almost 
grey ; while it assumes a brighter hue upon the loins and thighs. Tlie throat, 
neck, breast, abdomen, and the internal surfaces of all the limbs, are wliite. 
The tail is greenish above and grey beneath. The skin of the face, the 
ears, and hands, is of a clear copper-colour, and destitute of hairs. The 
thighs appear of a bright reddish-yellow, extending upon the crupper over 
the origin of the tail. The hairs are very fine and silky ; plentiful on the 
upper parts of the body, but scanty beneath. An extreme flaccidity may 
be remarked in all animals of this species, and the young have those hanging 
folds of skin on each side of the throat, which in other animals are seen 
only in old age. 
In the female, the thighs arc of a briglit red ; and this colour, which is 
entirely owing to tlie blood, appears on the legs, and upwards upon the 
crupper, towards the insertion of the tail, especially during the rutting sea- 
son. At tin's period the nipples are rose-coloured. 
The males differ from the females only in having their cheek-tufts more 
bushy, their proportions more massive, their height greater, and their ca- 
nines stronger.

The Hair greenish-brown above; witli a black band on the top of the 
head, extending along the back to the tail ; whitish beneath. 
The Tail very short and curved backwards. 
Inhabits Java and Sumatra. 
These animals have the same manners and disposition as the preceding. 
Their general colour is of a deep greenish-brown, proceeding from grey 
hairs annulatcd with black and yellow. The top of the head, for the 
breadth of two or three fingers, is black, and this sliade extends along the 
neck, back, and tail, but gradually acquiring the greeuish-hrown tinge. 
The latter colour covers the shoulders, becoming more yellow upon 
tlie fore-arm. The thighs are likewise green, but with a mixture of grey ; 
the cheeks, the under part of the chin and neck, the breast, abdomen, 
under surface of the tail, and the internal surfaces of all the limbs, arc 
white or flesh-coloured. Before the ears, at their base, and on the clieeks 
beneath the eyes, there are some blackish hairs, and behind the ears they 
are entirely black. The dark brown face is almost naked from the eyes 
to the mouth, with the exception of a few long and black hairs. The 
ears and the palms of the hands are naked, and of the same colour as the 
face, so are also the callosities. The males and females resemble each 
other in colour, and the young are of a brighter yellow than the adults.

SPECIFIC characters. 
The Hair of a uniform dark brown. 
The Face, Ears, and Hands, black. 
The Tail very short. 
Inhabits the East Indies. 
The characters of this species are obvious and decisive, forming a gra- 
dual transition into the third division, or Tailless Macacos. It rests, how- 
ever, merely upon a single specimen, sent by M. Alfred Duvaucel from 
the East Indies, and has by some been considered identical with M. niger 
(1 1). The specific name Maurm is derived from the colour of the face 
and hands, and that of Ursine from the resemblance of its hair to that of 
the Brown Bear (Ursiis Arctos). 
There is a variety of this species, sent by M. Diard from Cochin-China, 
and figured by M. Isidore Geoffroy (F,tud. Zool. pi. 1 1), under the name 
of Le Macaque Ursin, which appears to differ from the above, in liaving 
the nose alone black, with the face and hands flesh-coloured. Its dark 
brown hair is also scantily dotted with clear red. The specimen was 
about two feet ten inches in lengtli. 
(C.) Tailless Macacos. (Macots.) 
These are merely Macacos, in which a small tubercle supplies 
the place of a tail.

The Hair of a briglit greyish^ycllow.

Inh.vbits the North of Africa and lire Rock of Gibraltar. 
Of all Apes, the present speciess seems best capable of enduring 
our climate. Originally from Barbary, it has become naturalized 
upon the most inaccessible parts of the Rock of Gibraltar. 
In size tlie Barbary Macaco never exceeds a middle-sized Dog. The 
top and sides of the head, the cheeks, neck, slioulders, the corresponding 
[larts of tlie back, and the fore part of the anterior limbs, are of a bright 
gold-yellow, mixed with a few black hairs. The other parts of the body 
are of a greyish-yellow. Each hair is of a dark grey at its base, and an- 
nulated with yellow and grey throughout the rest of its length. The face 
and ears are wliolly naked, and of a bright flesh-colour. The tips of the 
e.iTS are covered with long hairs, tlie hands are blackish and well furnished 
with liair. Tlie cheek-tufts arc tliick and directed backwards. All parts 
of the body are covered with hair, liaving the points directed downwards, 
excepting on tlie fore-arm, where they point upwards. The entire coat 
is very long, dense, and uniform ; for whicli reason, these Monkeys become 
best able to resist the cold during the winter. 
The Barhiiry Ape walks liabiiually on all its four hands, but without 
ease, .as it is more especially organized for climbing. It sleeps either on 
the side, or in a sitting posture, with the head between its hind-legs, 
raises the food to its mouth by the hand, or seizes it with the lips ; a>'
