Varieties occur with the shoulders and loins pale yellow, instead of mixed black and brown, and the outside of the thighs and the base of 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.
