352 CLASS MAMMALIA. 



terminate the division of the monkeys, but precede the 

 Macaques, the Pongos, and Baboons, which form the last 

 families. 



Audebert, in his magnificent work on the monkeys, differs 

 somewhat from Buffon in his method of arrangement. He 

 divides the Quadrumana into six families. The four first 

 present a view of the species belonging to the ancient con- 

 tinent, the character of which is to have the partition 

 which separates the nostrils extremely slender, so that their 

 openings are nearly contiguous and underneath. 



The first family comprehends those monkeys which, by 

 the conformation of their head, approximate the nearest to 

 the human species. Such are the Orang-Outang, Gibbon, 

 fyc. They have no tail. 



This family he divides into three sections. 



The second and third families correspond to a part of the 

 Macaques and to the Baboons of Cuvier. 



The fourth contains the Guenons. 



The monkeys of the two last families are peculiar to the 

 new world, and are easily distinguished from those of the 

 old, by the thickness of the partition which separates their 

 nostrils. This partition is as large or larger than the mea- 

 surement of the nostrils in the greatest width of their 

 diameter. 



The fifth family is devoted to the Sapajous, whose tail is 

 revolute and prehensile. 



The sixth, in fine, is composed of the Sagoins, which have 

 the tail flexible, and not prehensile. 



For a list of the species of these numerous orders, with 

 their synonyma, fyc, we must refer to the Synopsis.
