APES AND MONKEYS. 
The Moustache Monkey (Cercopithecus cephus). 
In all the round-headed and short-muzzled guenons yet mentioned the nose and 
body are of the same colour. There is, however, another division of the guenons, 
in which the colour of the nose differs from that of the body. Out of the seven 
species of this subgroup recorded by Dr. Gray we shall select for notice the four 
which have been represented of late years in the Gardens of the London Zoological 
Society, premising that the whole seven are West African. 
The leading characters of the moustache monkey are to be found in the presence 
of a triangular blue mark on the nose and in the yellow whiskers. Its general 
colour is olive-green, speckled with yellow; the throat and under-parts being grey, 
the face and temples black, and the feet and hands blackish. 
The Hocheur Monkey (Cercopithecus nictitans). 
The hocheur monkey is one of several species belonging to this subgroup of 
guenons, collectively known as white-nosed monkeys, from the circumstance that 
the nose in all of them is covered with white hairs. This particular species is 
distinguished by the blackness of the fur on both the upper and lower surfaces of 
the body, that of the back being finely speckled with yellow. The naked part of 
the face is of a bluish-black colour; the upper eyelids are flesh-coloured, and the 
hands and feet jet black. 
This species, sometimes known as the larger white-nosed monkey, may be 
readily distinguished from the next, not only by its superior size, but also by its 
more prominent nose. It has been described as lively and good-natured, but not 
so gentle and familiar as the next species, and more resembling in its temper and 
general character the mona monkey. It has been obtained both from Fernando Po 
and Guinea. 
The Lesser White-Nosed Monkey (Cercopithecus petaurista). 
This elegant monkey, which comes from Guinea and Sierra Leone, is one of the 
smallest of the guenons. It was described in the works of the French naturalist 
Buffon under the well-chosen name of Blanc-nez ; and is readily distinguished, as 
we have said, from the hocheur by its smaller size and the flatness of its nose, as 
well as by the lighter tint of the under-parts. In colour the fur of the back is 
olive-green, speckled with yellow; the face black; the white spot on the nose small 
and nearly triangular; and the cheeks, chin, under-parts of the body, the inner 
sides of the limbs, and the under side of the tail white. 
The following account of the habits of this species in confinement is taken from 
an anonymous writer, who states that the manners of this monkey “ are playful and 
engaging beyond any other species we have ever observed, and it has an amiability 
and innocence in its conduct and expression which, united to its lively and familiar 
disposition, never fail to make it a prime favourite with its visitors. An individual 
of this species, which formerly lived in the Gardens of the Zoological Society, was
