1896.] ANTELOPE FROM EAST AFRICA. 193 
ADENOTA THOMASI, sp. nov. 
Colour nearly or quite the same as Adenota kob. Size larger. 
Skull and horns much larger than those of A.kob. The ridges of the 
horns much more rounded and less sharp than in A. kob. Colour 
of the horns basally light horn-yellow, gradually becoming darker 
at the points; while the horns of A. kob are nearly uniformly 
blackish. 
Adenota vardoni, to which the horns of A. thomas come nearest, 
although generally shorter, is distinguished by the total absence 
of black colour on the legs, while A. leché is distinguished by its 
far larger size and longer horns. Young specimens of A. kod, 
A. thomasi, A, vardoni, and A. leché may be difficult to distinguish.
