COLOBUS ABYSSIMCUS CAUDATUS. 

 Colobus guereza caudatus, Thomas, Proo. Zool. Soo, 1885, p. 219, pi. xii. 



Distinguished from the Abyssinian Guereza by having the white 

 brush of the tail very much larger, only about 3 to 6 inches of the 

 base .of the tail being black; the white hairs of the body-mantle, 

 as a rule, entirely cover the black basal part of the tail. 



Typical locality, Useri, north-east slopes of Mt. Kilimanjaro. 

 There can be but little doubt that this monkey is fairly widely 

 distributed throughout Kenya Colony. Several different races of 

 the East African White-tailed Guereza have been described, but 

 the distinguishing characters are perhaps of doubtful systematic 

 value. Owing to the licensing restrictions now in force it is 

 rarely that more than one or two of these monkeys are obtained 

 from the same locality, and in dealing with. such small differences 

 of coloration as have been used to distinguish these various 

 forms, a large series of specimens is needed before such differences 

 can be accepted as being of any systematic importance.
