The Genus Presbytis is repre- 

 sented by the Tailed Gibbon, which 

 inhabits Sumatra. 



The Genus Cercopithecus Gue- 

 nons is characterized by a mod- 

 erately prominent muzzle, long tail, 

 and the last of the inferior molars 

 with tubercles like the rest. The 

 species are numerous, and of great 

 variety of size and color. They live 

 in troops, and commit great havoc in gardens and culti- 

 vated fields. They are easily tamed. 



The Genus Colobus Thumbless Apes comprises a 

 few African species closely related to the solemn apes. 



The Genus Macacus Macacos is characterized by 

 a fifth tubercle on their last molars, and their limbs are 

 shorter and thicker and muzzle more projecting than in 

 the Guenons. 



The Genus Imms comprising the Barbary Ape 

 differs from the Macacos mainly in having a small tuber- 

 cle instead of a tail. This ape inhabits the precipitous 

 sides of the Rock of Gibraltar. 



The Genus Cynocephahis 

 Baboons is characterized by 

 a dog-like muzzle. The Ba- 

 boons are mainly inhabitants 

 of Africa and the Philippine 

 Islands, and are large, fero- 

 cious, and dangerous ani- 

 mals. They are essentially 

 constructed to live upon the ground, and are inferior to
