50 MAMMALIA, QUADRUMANA. 



C. hamadryas, Desm. (Simla hamadryas, Lin.) Dog-faced Ba- 

 , boon. Fur ash-coloured ; mane and beard very long ; face flesh- 

 coloured ; hands black. Inhabits the environs of Moca on the 

 Persian Gulf. -Shaw, i. pi. 15. 



Sub.-Gen. 2. MANDRILLS With a very short and slender tail per- 

 pendicular to the dorsal spine. 



C. mormon, Desm. (Simia maimon, Lin.) The Mandril or Varie- 

 gated Baboon. Fur grayish brown or olive above, white below ; 

 If beard yellow ; face blue in the adult ; nose red in the male. 



This is among the largest of apes, since it attains sometimes the height of five 

 feet when on its hind legs. Young males and females have the muzzle shorter, 

 and of a uniform blue. The nose of the males does not become red till their ca- 

 nine teeth are fully developed, when the wrinkles of their face begin to appear. From 

 the Gold Coast and Guinea in Africa. Shaw, i. pi. 10. 



C. leucophceus, Desm. (Simia leucophcea, Fred. Cuv.) Fur grayish 

 r\ brown, greenish above, white below ; face of both sexes at all 

 ages of a deep uniform black. About three feet in length. 



The three following species, viz. The wood Baboon, Penn. Simia sylvicola, Shaw ; 

 the yellow Baboon, Penn. S. siiblutea, Shaw ; and the Cinereous Baboon. Penn. 

 S. cinerea, Shaw ; together with the S. apedia of Linnseus, seem in M. Desmarest's 

 opinion to have great affinity with the preceding, and perhaps to hare been establish- 

 ed from ill -preserved species. 



C. Niger, Desm. Fur black ; hair woolly, except that on the top 

 of the head, which is lank, and forms a tuft on the occiput ; no 

 tail ? From the Indian Archipelago. 



2d TRIBE. APES OF THE NEW CONTINENT. 

 (Simice Platyrrhini, Geoff.) 



Six molars on each side of both jaws, with blunt tubercles, or 

 five only with sharp tubercles. Partition of the nostrils 

 broad ; nostrils opening on the sides of the nose ; tail al- 

 ways long, often prehensile ; buttocks hairy, never with cal- 

 losities ; no cheek-pouches ; head generally rounded. 



They live in troops as the other apes, feeding on fruits, roots, and sometimes in- 

 sects : but are less turbulent and lascivious than those of the Old Continent. They 

 inhabit South America from Mexico to Paraguay, particularly the wooded and well- 

 watered districts situated to the east of the chain of the Andes, Guiana, Brazil, 

 Para, a part of Peru, &c.
