Characters—Fur soft and stiff. Head large and round 
covered with short recumbent hairs. Face naked, pale round 
the prominent eyes ; muzzle sharp, and of the same colour as 
that which surrounds the eyes; forehead, temples, throat, 
chest, under surface of body, sides of jaws, and front of arms, 
pale orange-yellow ; outer side of arms, pale orange, washed 
with white; fore-arms, rump, hind-limbs, and tail black; 
a mixture of black and brown, expanding irregularly into spots 
on the yellow, covering the back, shoulders, and sides of body ; 
a spot on the crown, black; a superciliary ridge forming a band of 
whiskers extending down the cheeks, and meeting under the 
chin, also black. Hands naked, violet, almost black. 
Varieties occur with the shoulders and loins pale yellow, 
instead of mixed black and brown, and the outside of the thighs 
and the base ot the tail, reddish. In some specimens the pale 
yellow of the back gives place to a white ground. 
Distribution. Rio de Janeiro, Brazil ; Paraguay (?); Guiana. 
Habits.—Little is known of the habits of this species ; but 
F. Cuvier, who had one under his care in the “ Ménagerie 
Royale,” in Paris, remarks that it had the confiding disposition 
characteristic of the Capuchins, although very timid. It 
exhibited a great desire to be caressed, was very affectionate 
and most intelligent. Its physiognomy, however, he says, 
was involuntarily repellent, being one that, among ourselves, 
would indicate a person steeped in ignorance and sensuality.
