Show 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 OLDFIELD THOMAS, F.Z.S., Natural-History Museum. [Received March 2, 1885.] (Plate XII.) The Mammalia collected by Mr. Johnston during his late expedition 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, b. 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. nov. (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 bodv-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 w h o m a drawing is given in Mr. Johnston's forthcoming work, is made of the skin of this animal, but this is, of course, a rather vague indication of the original locality of the |
