This species singularly enough is nearest to E. kerstingi from 

 West Africa. Two specimens were obtained, both males. They were 

 in troops of from four to a dozen, in entirely open country and 

 were very difficult to approach. 



My friend the Rev. Dr. W. S. Rainsford, who obtained this 

 monkey in East Africa, (specimen presented to Am. Mus. Nat. Hist., 

 N. Y.,) says: "The monkey, (Erythrocebus whitei) I shot on the 

 N'soia Plateau. It is a very shy and very active species living on a 

 level country where there are no high trees, often no trees at all. 

 Indeed it avoids high and thick woods, where other monkeys are usually 

 found. This flat country is so infested with lions and leopards that all 

 the activity and cunning of the native is frequently called into play to 

 escape them. I have even known lions of that region to hunt down 

 and devour a cheetah. 



"I saw the monkeys several times but only once did I succeed in 

 getting a shot. I never saw more than three of them together and I 

 found them harder to stalk than any other animal I followed in 

 Africa."
