 region ; and from C. callitrichiis^ described below, by the more 

 sombre colour of its hair, the white superciliary band, and the 

 long white whiskers. Length of body, about 19 inches ; tail, 22 

 inches. 



Distribution. — North-east Africa : throughout Abyssinia, Sen- 

 naar, and Kordofan, up to 4,000 feet. 



Habits. — According to Dr. Blanford, this species is a true 

 tree Monkey, and is very rarely seen except in the forest. 

 " On the highlands of Abyssinia," he says, " I only once saw a 

 flock — this was near Dildi, south of Lake Asbangi. I met 

 with larger flocks on the Anseba, where they inhabited the 

 high trees on the banks of the stream. The flocks seen were 

 small, not exceeding twenty to thirty individuals. I had but 

 few opportunities of observing their habits, but they appeared 

 to differ but little from those of Macacus or Inuiis, except that 

 Cercopithecus is a quieter animal and less mischievous. In 

 captivity they are well known as excessively docile and good 

 tempered, and fairly intelligent."
