206 CATALOOUE OF UNGULATES 



young animals with short, velvety, white hairs ; fore-legs 

 generally hlack in front from knees to hoofs, fawn on outer 

 and white on inner surface ; hind-limbs frequently with 

 similar black markings on lower part of shanks ; tail thick, 

 bushy, and reaching half-way to hocks, with the root and 

 upper surface fawn, and the tip and under side white. 

 Horns relatively long, with a moderate but not abrupt 

 hook-like curvature at tips ; the growing pad at their bases 

 persistent throughout life as a soft, rounded swelling. Good 

 horns range from 15 to 17^ (18, it is stated in one instance) 

 inches in length, and from 5 to 6^ (in one case 7^) inches in 

 girth, with a tip-to-tip interval of from 9^ to 20i inches. 

 Basal length of skull about 10^ inches (259 mm.), maximum 

 width 4| inches (120 mm.), interval between muzzle and orbit 

 6^ inches (158 mm.). 



The French-grey form from Nyasaland described as 

 Cervicapra thomasinm seems to be merely an excessive 

 development of the greyness characteristic of this species, 

 and is probably restricted to individuals sprung from a 

 single parent stock. The resemblance in colour of this phase 

 to Fdea is very notable. 



The range extends from South Africa to the Bahr-el- 

 Ghazal on the eastern side of the continent, and as far north 

 as Angola on the west. 



The following two closely allied races are recognised : — 



A. Head and neck fulvous ; bodj', limbs and tail 



greyish fawn B. a. arundinum. 



B. Head and neck greyer fulvous ; body, limbs, and 



tail rusty grey B. a. Occident alis. 



A.— Redunca arundinum arundinum. 



Typical locality Cape Colony, whence the range extends 

 (exclusive of Northern Rhodesia and the Bangweolo Flats) 

 to the Bahr-el-Ghazal, where it overlaps that of R. redunca 

 boJior.
