BUSHBUCKS, KOODOOS, AND ELANDS 437 
buck from the headwaters of the ’Nzoia River immediately 
above the Kavirondo country are dark-colored like dela- 
merei , old males from this elevated region being quite as 
dark as any from the Aberdare Mountains. The record 
horn length of this race recorded by Ward is 18^ inches, 
based on a specimen shot in Unyoro by F. A. Knowles, the 
district commissioner.

watershed to the headwaters of the Congo system. 
Heuglin described the bushbuck of the Bahr-el-Ghazal 
region in 1877, giving to it the name bor , by which it was 
known to the Djengs who dwell in the country lying be¬ 
tween the mouth of the Sobat and the Bahr el Zeraf. Doctor 
Schweinfurth also met with it during his travels in the up¬ 
per Bahr-el-Ghazal district in 1869. He makes mention of 
its extreme shyness, solitary habits, and the ease with which 
it is detected by the eye, owing to its striped coloration. 
In an appendix to his narrative of his travels he furnishes a 
long list of names by which the bushbuck is known to the 
various tribes he encountered. 
The Nile bushbuck is scarcely distinguishable from the 
typical race from West Africa. The male may be dis¬ 
tinguished by the collar on the nape, and the darker throat, 
but the color pattern is quite the same as in scriptus . The 
female cannot be distinguished from the typical form. It 
is quite remarkable that the bushbucks show practically no 
racial variation from the Nile to Senegal, a distance of three 
thousand miles, while eastward they break up into several 
races within an area of less than one thousand miles’ width. 
From delamerei it is distinguishable by its numerous trans¬ 
verse stripes, the single longitudinal stripe, and the rufous 
color of the adult male. It approaches more closely dama 
in coloration, but is readily distinguishable by the presence
