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 5^ inches. Ward recorded one of 6)4 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, inches; ear, 4 inches. Skull 
length: male, 6)4 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.

Range.- —Limited to a small area along the Tana River 
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, haggardly with which it was no doubt one time 
connected by way of the Tana Valley. 
Like haggardi y it is distinguishable from other races by 
its black tail. In coloration it may be described as quite 
intermediate between the tawny cottoni and the clay color 
or buff of the coast race. From haggardi it is easily dis-
