THE SAPAJOUS, OR CAPUCHIN MONKEYS 155 



forth into the air without a moment's hesitation, and alights on the dome of yielding 

 foliage belonging to the neighboring tree, maybe fifty feet beneath ; all the rest fol- 

 lowing his example. They grasp, on falling, with hands and tail, right themselves 

 in a moment, and then away they go along branch and bough to the next tree." 

 The same traveler, who had one of these monkeys as a pet, states that it kept 

 the house in a perpetual uproar, screaming in a piteous manner when alarmed, 

 excited, or hungry. It was always making a noise of some kind ; frequently screw- 

 ing up its mouth and uttering a succession of loud whistling notes, resembling those 

 mentioned by Rengger in his account of the preceding species. Frequently this 

 young sapajou, when following its master, would walk upon its hind legs alone, 

 although it had never been taught to do so. One day, however, in endeavoring to 

 wrest some fruit from an owl-faced night monkey, it attacked the latter so fiercely 

 that it cracked its skull with its teeth, upon which Mr. Bates considered that he 

 had had enough of pet sapajous. 



THE WHITE-THROATED SAPAJOU (Cebus hypoleucus) 



This species, represented in the lower figure of the illustration on p. 149, is an 

 inhabitant of Central America. It belongs to the same group as the preceding one, 

 from which it is distinguished by its coloration. Thus, while the general color of 

 the fur is black, the forehead and part of the crown of the head, as well as its sides, 

 together with the throat and neck, are white ; while the naked portion of the face is 

 of a pale flesh color. 



THE SMOOTH-HEADED SAPAJOU (Cebus monachus) 



The smooth-headed, monk, or yellow-headed sapajoU, is a species from Rio 

 Janeiro and other places in Southeastern Brazil, which takes all three of its names 

 from the extremely close and short yellow hair with which the front of the head 

 is covered. It is represented in the left-hand upper figure of the illustration on 

 p. 149. 



The fur of this species is very short and stiff. In color, the crown of the head, 

 the whiskers and chin, together with the shoulders, haunches, limbs, and tail, are 

 pure black ; the sides and back, more especially in the hinder half of the body, are 

 yellow, more or less mixed with black ; while the sides of the neck, the chest, and 

 the front of the shoulders are yellow ; the forehead and temples being whitish 

 yellow. Such is the striking coloration of the typical form of this species, but there 

 are several variations therefrom, and the specimen represented in our illustration 

 belongs to an olive-colored variety, which has been described as a distinct species, 

 tinder the name of C. olivaceus. 



THE CRESTED SAPAJOU (Cebus robustus} 



The last member of this genus we shall notice is the crested sapajou of Brazil. 

 This species is distinguished from all those previously mentioned by the long hair
