308 ANIMALS OF EGA. Chap. V. 



covered with hair, and of little or no service in climbing, 

 a few species nearly related to our Uakari having it much 

 shorter than usual. All the Cebiclse, both long-tailed 

 and short-tailed, are equally dwellers in trees. The 

 scarlet-faced monkey lives in forests, which are inun- 

 dated during great part of the year, and is never known 

 to descend to the ground ; the shortness of its tail is 

 therefore no sign of terrestrial habits, as it is in the 

 Macaques and Baboons of the Old World. It differs a 

 little from the typical Cebidse in its teeth, the incisors 

 being oblique and, in the upper jaw, converging, so as 

 to leave a gap between the outermost and the canine 

 teeth. Like all the rest of its family, it differs from 

 the monkeys of the old world, and from man, in having 

 an additional grinding-tooth (premolar) in each side of 

 both jaws, making the complete set thirty-six instead of 

 thirty-two in number. 



The white Uakari (Brachyurus calvus), seems to be 

 found in no other part of America than the district just 

 mentioned, namely, the banks of the Japura, near its 

 principal mouth ; and even there it is confined, as far as 

 I could learn, to the western side of the river. It lives 

 in small troops amongst the crowns of the lofty trees, 

 living on fruits of various kinds. Hunters say it is 

 pretty nimble in its motions, but is not much given 

 to leaping, preferring to run up and down the larger 

 bouo-hs in travelling from tree to tree. The mother, as 

 in other species of the monkey order, carries her young 

 on her back. Individuals are obtained alive by shooting 

 them with the blow-pipe and arrows tipped with diluted 

 Urari poison. They run a considerable distance after being
