The flesh measurements of this race are: head and body, 
37 inches; tail, 3X inches; hind foot, n inches; ear, 
inches. Average length of skull: 6}4 inches in males, 6^ 
inches in females. The usual length of horn is 4 inches. 
The longest horns in a series of seven measure 4^ inches. 
A series of twenty specimens have been examined repre¬ 
senting the Lado Enclave, Nimule, Gondokoro, and the 
highlands one hundred miles east of it, and the Bahr el

opposite sides of the Nile. Considering the low altitude 
and the torrid nature of the Nile Valley, this race shows 
comparatively slight color and pelage difference from cot - 
toni of the cold highlands of the Uasin Gishu Plateau.

the oribi is abundantly distributed. In this locality Major 
Powell-Cotton collected the type of the race which now 
bears his name, but Jackson was the first sportsman to record 
the oribi from the Uasin Gishu, where he met with it on his 
pioneer trip to Uganda in 1889. Hollister, the assistant 
curator of mammals at the National Museum, described in 
1910, from a skull collected on the Uasin Gishu by J. J. White, 
a species which he named microdon , basing the name on the 
small size and the straight outline of the cheek-teeth. This 
skull, however, represents the extreme variation in size and 
shape of teeth in cottoni. The large series of skulls in the
