1885.] ON MAMMALS FROM KILIMA-NJARO. 219 



2. Report on the Mammals obtained and observed by Mr. 

 H. H. Johnston on Mount Kilima-njaro. By Oldi'ield

[Received March 2, 1885.] 



(Plate XII.) 



The Mammalia collected by Mr. Johnston during his late expe- 

 dition to Kilima-njaro nearly all belong to common and widely 

 distributed species ; but his observations on the vertical distribution, 

 comparative rarity, native names, &c., of the different mammals of 

 the district are well worthy of being recorded. 



The following were the species observed by Mr. Johnston, the 

 numbers of those of which specimens were not brought home 

 being placed within brackets. 



1. Cercopithecus pygerythrus, Geoffr. 



a, h. Moshi, on the south side of the mountain, 5000 feet, June 

 to August. 



Very common in the cultivated gardens round the village, and in 

 the forests lower down at Taveita. These Monkeys are exceedingly 

 familiar and mischievous, coming into the gardens to steal fruit, &c., 

 and are entirely without any fear of man. 



2. CoLOBUs GUEREZA CAUDATUS, subsp. uov. (Plate XII.) 



a. Useri, N.E. flank of mountain, 3000 feet, end of October, 



Very common all round the base of Kilima-njaro. 



The specimen brought, like two or three beautiful skins obtained 

 by Mr. Thomson in the same neighbourhood, belongs to a peculiar 

 race or variety apparently restricted to this region, and characterized 

 by having the white brush of the tail very much larger and finer 

 than is the case in the true Abyssinian C. guereza. In the latter 

 animal the proximal 12 to 16 inches of the tail is short-haired and 

 quite black, only the terminal 8 to 12 inches being white and tufted, 

 and the white mantle hanging down from the body hides only about 

 one third of the black part of the tail. In the Kilima-njaro race, 

 however, only some 3 or 4 inches of the base of the tail are 

 black, and the remainder (with the hairs about 20 or 21 inches) is 

 developed into a magnificent white brush, of which individual hairs 

 are from 7 to 9 inches in length. The hairs of the white 

 body-mantle, moreover, entirely cover the black at the base of the 

 tail, the white of the latter and of the mantle being quite continuous. 



In addition to this race, however, the true Guereza is also found 

 in the neighbourhood of Kilima-njaro, as the mantle of the lowland 

 Masai warrior, of whom a drawing is given in Mr. Johnston's forth- 

 coming work, is made of the skin of this animal, but this is, of 

 course, a rather vague indication of the original locality of the
