224 ZOOLOGY. 



Presbytes. Doubtless the association in such very large 

 herds is in a great measure adopted as a means of defence 

 against its enemies. From their size and great power of 

 jaw the old males are most formidable antagonists, and 

 their boldness in resenting injury is said to be in propor- 

 tion to their power. Brehm ( ' ' Keise nach Habesch, "p. 88) 

 relates an instance which came under his own notice of 

 their attacking a Leopard which had carried off one of the 

 herd, and many stories are current in Abyssinia of their 

 attacking men. Mr. Miinzinger told me that once he, 

 with one or two companions, were surrounded by a large 

 herd, which barred their path, and were so threatening 

 that he was obhged to shoot one in self-defence. Even 

 then, although they fell back a little, the Monkeys did 

 not run away. 



I cannot help thinking, however, that these Monkeys 

 very rarely attack men, as otherwise some instances 

 would have happened in the expeditionary force, and I 

 never heard of any. Near the passes the flocks of 

 Cynocephalus soon became wary, as they were frequently 

 fired at. Young animals, when captured, quickly became 

 tame and docile, but not so much so as the Cercopithecus.

I met with this monkey but rarely. Unlike the 

 Cynocephalus, it is a true tree-monkey, and very rarely 

 seen except in forest. On the highlands I only once saw 

 a flock— this was near Dildi, south of Lake Ashangi. 

 I met with larger numbers on the AnseLa, where they
