Habitg-—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,o00 feet above 
the sea.
