This species resembles closely in body size and horn 
shape the Zambesi lechwi, but differs widely in coloration. 
The dorsal coloration of the male is bay or seal-brown with 
a large whitish patch on the withers extending along the nape 
and spreading over the crown of the head, the ears, and the 
orbital region. The tail is white with a black tuft at the tip. 
The under-parts and hoof bands are white. The female is 
uniform buffy in color on the dorsal surface, but the cheeks 
are dark-brown and the orbital region whitish with a light 
preocular stripe. In a normally colored adult male the dor¬ 
sal color of the body is raw sienna merging on the sides to a 
light olive-gray, the under fur being everywhere seal-brown 
and showing through on the sides where the olive-gray only 
overlies the hair lightly. The tail above is lighter, buffy, and 
the tip black. The sides of the neck and the throat have 
the seal-brown predominating like the sides, and overlaid 
sparingly by a few buffy hairs. The withers are marked by 
a large oval area of whitish hair overlaid by a wash of raw 
sienna, the light area extending forward along the nape to 
the crown, where it includes the ears and broadens out 
greatly; on the nape it narrows down to a mere line, the 
whole area being in outline much like a dumb-bell. The 
legs are dusky-brown like the sides, being overlaid by light 
olive-gray. The hoofs and false hoofs are marked by a 
light band of cream-buff above the hairless border. The 
under-parts are white from the chest to the base of the tail 
as well as the inside of the hind legs. The forelegs at the 
axilla and on the inside are dusky-brown with a patch of 
buffy on the inside of the thighs. The side of the head is 
uniform seal-brown to the lower margin of the orbit, the 
seal-brown area being continued across the snout and up 
the forehead to the base of the horns. There is a wide 
cream-buff or whitish supraocular stripe continuous with 
the white area of the crown and the ear base. The back of 
the ear is buffy and the base and the inside are white. The 
snout has a broad tawny patch on each side and the nos¬ 
trils and lips are bordered narrowly by white. The chin is 
white and merges gradually into the ochraceous-tawny fore¬ 
throat. The rest of throat to the chest is seal-brown like 
the sides and overlaid by light olive-gray sparingly. An 
old adult male is brighter red, the body behind ferruginous;
