CERCOPITHECIDA 721 
It is only to fully adult males that this description applies. 
The female is of much smaller size, and of more slender make; 
and, though the general tone of the hairy parts of the body is 
the same, the prominences, furrows, and colouring of the face are 
very much less marked. The young males have black faces. At 
the age of three the blue of the cheeks begins to appear, but it is 
not until they are about five, when they cut their great canine 
teeth, that they acquire the characteristic red of the end of the 
nose. 
The Mandrills, especially the old males, are remarkable for the 
ferocity of their disposition, as well as for other disagreeable quali- 
ties, which are fully described in Cuvier’s account of the animal in 
Fig. 345.—The Yellow Baboon (Cynocephalus babuin). From Archives du Muséum, 
vol. ii. pl. 34. 
La Ménagerie du Muséum d'Histoire Naturelle (1801), but when 
young they can easily be tamed. Like the rest of the Baboons, 
they appear to be rather indiscriminate eaters, feeding upon fruit, 
roots, reptiles, insects, scorpions, etc., and inhabit open rocky 
ground rather than forests. Not much is known of the Mandrill’s 
habits in the wild state, nor of the exact limits of its geographical 
distribution. The specimens brought to Europe all come from the 
west coast of tropical Africa, from Guinea to the Gaboon. 
An allied species, the Drill (C. lewcophieus), which resembles the 
Mandrill in size, general proportions, and shortness of tail, but 
wants the bright colouring of the face which makes that animal so 
remarkable, inhabits the same district. Other well-known species 
are the Yellow Baboon (C. babwin), of West Africa (Fig. 345); the 
Arabian Baboon (C. hamadryas), of Arabia and Abyssinia ; and the 
Anubis Baboon (C. anubis), of West Africa.
