whitish. But all the other shades of their 

 bodies vary between a brownish-black and fawn 

 colour, and sometimes a whitish colour; the 

 region of the shoulders, and of the breast is, 

 however, generally more pale, and the cap or 

 coif, and hands of a deeper colour. 



The Horned Sajou, {Simia fatuellus) Buff. Suppl. 

 VII. xxix. 



Is only distinguished by a small crest of hairs 

 on each side of the forehead. 



All these animals come from South America. Their 

 disposition is mild, their motions light and lively. 

 They are easily tamed. Their little soft cry has 

 occasioned them to receive the name of Weeping 

 Monkeys. In some of these (the Callitrix, Geoff.) 

 the tail almost seems to be prehensile. 



The Saimiri, {Simia Sciurca) Buff. XV. x. 

 Is one of these last ; as large as a squirrel, of a 

 greyish yellow. The fore-arms, the legs, and the 

 four hands, yellowish fawn-colour. The termina- 

 tion of the muzzle quite black. 



Those which have no prehensile tails are called 

 Sakis. Their tails are generally tufted, which 

 causes them also to be named fox-tailed monkeys. 

 These are the Pithecia of Desmarest and Illiger *. 



* In Buffon they are called in common with the Ouistitis, 

 Sagoins {Callitrix Erx.) This name of Sagoin or Cagui, belongs, 

 in fact, in Brazil^ to all the small quadrumana without prehensile 

 tails. M. Geoffroy
