RED HOWLER— OUAKARIS— SAKIS 47 



monkeys found in a cool climate, as it lives in the mountains of 

 Chilasco at an elevation of 6000 feet, where the climate is cold and 

 damp. There are only half-a-dozen species of Howlers altogether. 

 Most of the other South American monkeys are little known, with 

 the exception of the distinct family of the Marmosets, next to be 

 noticed, but it is convenient here to pass them in review. 



THE OUAKARIS 



The monkeys of this genus (Brachyurus) are of moderate size, but larger than 

 the Capuchins, and they are remarkable among New World monkeys for their 

 short tails, which are non-prehensile, and not half as long as the body. Unlike 

 the short-tailed monkeys of the Old World, however, they display no tendency 

 to come to the ground. They are fruit-eaters, gentle in disposition, and tender 

 in constitution ; but all the three kinds have been exhibited in the Zoological 

 Gardens. These are the Red Ouakari {Brachyums rubicundus), which has a 

 coat much like the Orang's and a bright red face; the Bald Ouakari (B. calvus), 

 which has also a red face, but a white coat ; and the Black-headed Ouakari (B. 

 melanocepkalus), which is black in the face and on most of its fur. They are all 

 South American, and each inhabits a separate small area. 



THE SAKIS 



The Sakis (Pithecia) are closely allied to the Ouakaris, but have long tails, 

 which are very bushy and not prehensile. Their whole coat is long and thick, 

 and mainly black in colour; and they are well bearded, the most conspicuous in 

 this respect being the Red-backed Saki {Pithecia chiropotes), at any rate in the 

 male sex, the female having no beard. The male is said to drink from its hands, 

 for fear of wetting this appendage. It is a fierce, unsocial animal, and hard to 

 tame, but has been exhibited at the Zoological Gardens, as have all the other 

 Sakis, four in number. The Hairy Saki (P. monachus) is said by Bates to be, 

 although not a lively animal, remarkable for its affectionate disposition when 

 tamed, at any rate to its owner. It is, however, very delicate; and none of the 

 Sakis are common in captivity. All are found in South America only.
