Cebus macrocephalus, Spix, Sim. et Vespert., Bras., p. 3, pl. 1 (1823).

CHARACTERS.--Fur thick, harsh; hair of crown short, reflexed; on the sides of the crown a dark spot, elongated and elevated into two longer or shorter crests, according to the season and the age of the animal. General colour reddish-brown, darker on the hind-limbs, tail, and middle of the back; fore-arms, crown-spot, and whiskers, black; front of shoulders greyish or yellow; Face naked, purplish flesh-colour.

This species is subject to great individual variation. Its general colour is sometimes pale yellowish, with the whiskers yellow.

DISTRIBUTION.--Brazil; Guiana, near the coast; on the mountains of the Upper Magdalena Valley; Tolima, U.S. Colombia, from 5,000 to 7,000 ft.

HABITS.--This species, called "Mico Maizero" by the inhabitants of Tolima, lives as all the Cebi do, in considerable troops in the forests. When wild, it is restless and destructive, but in captivity it is docile and affectionate.
