WATERBUCKS AND REEDBUCKS 523 



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;
