I04 ' APES AXn MOXKEYS. 



The Moustache Monkey (C'evcopithecus cephiis). 



lu all the round-headed and shoi-t-muzzled guenons yet mentioned the nose and 

 boily are of the same colour. There is, however, another division of the guenons, 

 ill wliich the colour of the nose ditiere from that of the body. Out of the seven 

 species of this subgroup recorded by Dr. Gray wo shall select for notice the four 

 which have been represented of late yeai-s in the Gardens of the Loudon Zoologiciil 

 Societ}-, jjremisiug that the whole seven are West African. 



The leading charactei-s of the moustivche monkey are to be found in the presence 

 of a triangular blue mark on the nose and in the yellow whiskei-s. Its general 

 colour is olive-green, speckled with yellow ; the throat and under-pails being grey, 

 the face and temples black, and the feet and hands blackish. 



The Hocheur Monkey (jCercopithecus 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 haire. This particular species is 

 distinguished by the blackness of the fur on both the upper and lower sui'faces of 

 the body, that of the back being finely speckled with yellow. The naked part of 

 the face is of a bluisji-black colour: the upj^er eyelids are flesh-coloured, and the 

 hands and feet jet black. 



This species, sometimes known as the larger wliitc-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 Femando Po 

 and Guinea. 



The Lesser White-Nosed Monkey (Cercopithecus petav/rista). 



This elegant monkey, which comes from Guinea and Siei-ra Leone, is one of the 

 smallest of the guenons. It w;us described in the works of the French naturalist 

 Button 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 iis by the lighter tint of the uuder-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-pai-ts 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 continement is taken from 

 an anonj-mous 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 tliis species, which formerly lived in the Gardens of the Zoological Society, was
