SECTION VI. 



AMERICAN MONKEYS. 



These are a very numerous division found in South America, 

 and arranged into two leading groups, viz. : the SAPAJOUS and 

 SAGOINS; the former having muscular, grasping tails; the latter 

 feeble ones, unfit for grasping. They are sometimes called the 

 four-fingered monkeys, as the thumb is reduced to a mere rudi 

 ment, and in some species is entirely wanting. They are with 

 out cheek-pouches and callosities. 



I. SAPAJOUS. 



These may be regarded as representing the GUENONS, (Cerco- 

 pithecus, Gr. kerkos, a tail,) of the Eastern Continent. The whole 

 of them are very active, climb well, and are well formed for living 

 and moving among the trees. The fore-hands show a less per 

 fect organization than is seen in the monkeys of the Eastern 

 Continent. The palms of both extremities are endowed with 

 exquisite sensibility. These monkeys are of small size and play 

 ful disposition. Gathered in herds, they lead a merry life, feed 

 ing mostly on insects and fruits. The facial angle is about 60o. 

 Among them we include the HOWLERS, (Mycetes.) as has been 

 done by other naturalists. The Howlers differ, however, from 

 the other Sapajous in some respects, particularly in having a 

 facial angle of but 30o, but agree with them in having prehen 

 sile tails. Of the numerous species of these and other South 

 American monkeys, we can notice only the most interesting and 

 prominent. 



Mycetes, (Gr. ^uxijrr/g, mukdtes, a Howler.) 



These are the largest monkeys of America, and remarkable 

 for the development of the vocal organs. The bone at the root of
