G6 MAMMALIA. 



a tail S. nigra, Cuv. ; but Avhose head resembles that of the 

 rest. The 



Mandrills, 



Of all the monkeys, have the longest muzzle (30); their tail is 

 very short; they are brutal and ferocious; nose as in the preceding. 

 Sim. maimon and mormon, Lin.; Boggo, Chorus, Buff. XIV, 

 XVI, XVII, et Supp. VII, 9. (The Mandrill.) Greyish brown, 

 inclining to olive above ; cheeks blue and furrowed. The 

 nose in the adult male becomes red, particularly at the end, 

 where it is scarlet, which has been the cause of its being 

 deemed, erroneously, a distinct species. (l) The genital parts, 

 and those about the anus, are of the same colour. The buttocks 

 are of a beautiful violet. It is difficult to imagine a more hide- 

 ous or extraordinary animal. He nearly attains the size of a 

 man, and is a terror to the negroes of Guinea. Many details 

 of his history have been mixed up with that of the Chimpanse, 

 and consequently with that of the Ourang-Outang. 



Sim. leucophsea, Fred. Cuv. Ann. du Mus. d'Hist. Nat. IX, 

 pi. 37, from a young specimen, and Hist, des Mammif. from 

 the adult. (The Drill.) Yellowish grey; face black; tail 

 very short and thin ; in old ones the fur becomes darker, 

 and the chin of a brilliant red. 



The Monkeys of America 



Have four grinders more than the others thirty-six in all; the 

 tail long ; no cheek-pouches ; buttocks hairy; no callosities; nostrils 

 opening on the sides of the nose, and not underneath. All the great 

 Quadrumana of America belong to this division. The large intes- 

 tines are less inflated, and the caecum longer and more slender than 

 in those of the eastern continent. 



The tails of some of them are prehensile that is, their extremity 

 can twist round a body with sufficient force to seize it as with a 

 hand. They are more particularly designated by the nameof Sapa- 

 jous, Cebus, Erxleben.(2) 



At their head may be placed the Alouattes (Mycetes, Illig.), 

 which are distinguished by a pyramidal head, the upper jaw of which 

 descends much below the cranium, as the branches of the lower one 



(1) 1 have seen, as well as M. Geoffroy, two or three Mandrills, or S. maimon, 

 change to the CJioras or S. mormon, in the Menagerie of the Museum. The tuft 

 of hair, which is fre<iuently given as a character of the mormon^ is often also in 

 the muimon. 



(2) Cebus or Cepus, or Kwo?, names of an Ethiopian Monkey, which, from the 

 description of iElian, lib. xxvii, c. 8, must have been the Patas.
