 with cheek pouches, and the baboons. The scientific name 

 signifies " dog-apes," but only some of them, the Cynocephali, 

 have much resemblance to our domestic favorite. The genera of this 

 family amount to Seven, which will be treated in this and the succeeding 

 chapter. 



I.— GENUS MYIOPITHECUS. 



This genus differs from the following genera by the development of 

 the brain, the shortness of the muzzle, and the structure of one of the 

 molar teeth. In the large ears and short face with an internasal septum 

 it somewhat resembles the American monkey. There is only one species. 



The Talapoin, Myiopithccus talapoin, is the smallest of the Old 

 World monkeys ; the fur is of a greenish hue, forming on the forehead

 yellowish. It is a very gentle creature, and exhibits in captivity intelli-

To this genus belong many of the monkeys seen in zoological 

 gardens or menageries, here and in Europe. Their generic characteris-
