Habit*. The habits of the " Gelada," as it is named by the 

 natives of its own country, are similar to those of the Baboons 

 (Cynocephalus). They live in large companies, and when full- 

 grown the males especially are very ferocious, pugnacious, 

 and dangerous. It is a common habit of these animals to roll 

 down stones from the rocky cliffs amid which they live, upon 

 any approaching animal the Arabian Baboon being an especial 

 object of their animosity. Their food consists of all sorts of 

 fruits, as well as grass, and the cultivated crops of the natives. 

 They are chiefly found in barren rocky regions, ascending the 

 mountains to an altitude of from 7,000 to 8,000 feet above 

 the sea.
