996 ON MAMMALS FROM THE ITURI FOREST. [Dec. 11, 



Provisionally, I propose to regard this Elephant-Shrew merely 

 as a race of Dr. Matschie's species, with the title of lih. stulil- 

 manni nudicaudata ; leaving it open whether it may not really 

 claim specific i-ank. 



In its completely naked tail, and apparently also ears, this 

 Elephant-Shrew is distinct from all other Rhynchocyons, unless it 

 be the typical stuhhnanni ; the one which comes nearest to it in 

 the former respect being Rh. chfysofygus. 



[Postscript.] 



[Since the foregoing paper was read Major Powell-Cotton has 

 sent home two skins and skulls of the Bufialo of the Semliki 

 Valley, in regard to which I communicated the following note to 

 the ' Field' newspaper of January 5th, 1907 (vol. cix. p. 87 '••). 



These specimens indicate an animal to a large extent inter- 

 mediate between the great black bufialo of South Africa and the 

 dwarf red bufialo of the west coast, and thus serve to strengthen the 

 view that these (and all other African) bufiialoes are merely races 

 of one and the same species. The general colour of the Semliki 

 buflfalo (which is well haired) is tawny, with the tip of the tail 

 black, but the tint gradually darkens towards the shoulders, till it 

 becomes blackish-brown on the neck and head. The tips of the ears 

 are, however, fringed with pencils of tawny hair. In size the animal 

 approaches the Cape bufialo, but the horns, which are thin and 

 much flattened, are, as in all the more northern races, widely 

 separated at their bases. The black tail-tip at once separates the 

 Semliki bufialo from Bos cafer mathewsi of the Albert Nyanza 

 district, in which that appendage is white (Proc. Zool. Soc. 1904, 

 ii. p. 163). With i^egaxd to the bufialo from Ankole, South 

 Uganda, described by Mr. O. Thomas (Proc. Zool. Soc. 1904, i. 

 p. 464) as B. caffe'>' radcliffei, it appears from specimens in the 

 Natural History Museum that the hair of that ra,ce is wholly 

 black. Among the numerous bufi'aloes recently described by 

 Professor P. Matschie (S.B. Ges. Naturfoi-sch. Berlin, July 1906) 

 none came from the Sem'iki district. The Semliki bufialo is 

 therefore apparently a new race, a,nd it is appropriate, that it 

 should be named, after its discoverer. Bos [Bubahts 1 cctffer cottoni. 

 Old individuals, I have recently found, become black.]

Major Cotton's specimen was obtained from the Itnri Forest, Central Equatorial 

 Africa, in the Mawambi district 13oth are drawn about y nat. size. 



* In the original note the specimen was stated to he from the Itnri Forest ; 

 hut this, I am informed by Major Cotton, is incorrect.
