DUIKERS AND SMALL ANTELOPES 561 



National Museum show every intermediate condition, from 

 skulls with large teeth, having tooth rows with convex out- 

 lines, to small teeth with the straight tooth row of microdon. 



The characters by which the race may be known are the 

 bright, tawny coloration, long pelage, and the large size and 

 heavily ringed horns. In horn length it exceeds all other 

 East African races. The average horn length is 4>^ inches, 

 but horns over 5 inches in length are not uncommon. The 

 longest specimen in the series of ten males in the National 

 Museum is ^^ inches. Ward recorded one of 6>^ inches 

 taken near the Uasin Gishu Plateau. The flesh measure- 

 ments of an average male are: head and body, 39 inches; 

 tail, 4 inches; hind foot, 4%^ inches; ear, 4 inches. Skull 

 length: male, 6yl inches; female, 6}4. 



Specimens have been examined from the Uasin Gishu 

 Plateau, the headwaters of the Amala River, on the German 

 border, and Karungu, on the east shore of the Victoria 

 Nyanza. They are known to occur at Londiana, near the 

 highest point reached by the Uganda Railway, and also 

 north of Elgon as far as the highlands forming the crest of 

 the Nile-Rudolf watershed.

 on the south slope of Mount Kenia, from Fort Hall east to 

 Embu Station and southward as far as the Ithangi Hills. 



The Kenia oribi has recently been described by its dis- 

 coverer. Lieutenant Minertzhagen from specimens which he 

 collected near Fort Hall. The race has a very restricted 

 habitat of a few square miles, and on this account has re- 

 mained so long unknown. It is allied more closely to the 

 coast oribi, haggardi, with which it was no doubt one time 

 connected by way of the Tana Valley. 



Like haggardly it is distinguishable from other races by 

 its black tail. In coloration it may be described as quite
