QUADRUMANA. 35 



These are represented in America by a great multi- 

 tude of species, called Spider Monkeys, or Sapajous, 

 and Sakis, arranged under the genera Cebus* Ateles, 

 Callithrix, &c. They are distinguished by an ad- 

 ditional molar tooth in each jaw, possessing thirty- 

 six teeth in all, whereas the Quadrumana hitherto 

 spoken of, have but thirty-two, as in Man. They 

 have no callosities, and no cheek-pouches; the tail 

 is long, and, in a large number of species, prehensile ; 

 the tip being capable of twisting round a branch or 

 similar projection so firmly as to support the weight 

 of the body, answering the purpose of a fifth hand. 

 Their voice is often loud and wailing, whence they 

 are sometimes designated Howling Monkeys. The 

 flesh is eaten, and is said by Mr. Waterton to be 

 palatable. 



We now come to a tribe which, of all the typical 

 Quadrumana, is the most brutal both in form and 

 manners. It is the genus 



Cynocephalus^ the Baboon. 



These are large animals, which, instead of the 

 small flattened nose of the Apes, have it prolonged 

 into a great muzzle, terminating abruptly, much 

 resembling that of a dog. They have cheek-pouches 

 and callosities, and a comparatively short tail, often 

 erected. They inhabit Africa and India ; where spe-
