colored and makes a conspicuous mark, as the movements of the 

 animal bring it into view. 



Riippell, who first discovered this species in the mountains of 

 Abyssinia gives the following short account of its habits as observed 

 by him : 



"The Abyssinian name of this Ape is Gelada, and he lives in large 

 families in regions covered with shrubs and rocks, keeping always on 

 the ground. The food consists of seeds, roots and tubers, and rarely 

 do they carry their depredations into cultivated fields. I observed 

 the Gelada in the mountainous districts of Heremat, Simen and 

 Axum, elevated regions 7,000 to 8,000 feet above the level of the sea. 

 They retire to caves and fissures of the rocks, and when captured they 

 make a loud noise resembling hoarse barks, but never defend them- 

 selves against men as the Cynocephalus hamadryas are accustomed 

 to do." 



Evidently the habits of this species are very similar to those of 

 Papio hamadryas, and doubtless such a powerful animal, as the 

 Gelada undoubtedly is, would prove to be an equally formidable 

 antagonist, and Riippell's statement that they never defend themselves 

 against men, must refer to the young, as one cannot but believe that 

 the capture of an adult, especially of an old male, would be quite a 

 serious undertaking.
