but the feet decidedly longei^, though both the specimens are imma- 

 ture. In three fully adult specimens of sharpei the hind feet, 

 including hoofs, measure 196-198 mm., while in the two Letaba 

 individuals, which still retain their milk-dentition, this dimension 

 is 208 and 215 mm. 



Genei'al colour slightlj^ richer and moi'e purplish than in true 

 sharpei, the intermixed white hairs more numerous. Throat, 

 chest, and belly purplish buff, the line of demarcation on sides of 

 belly little marked ; in sharpei the under surface is white or whitish 

 with but little tinge of buffy. 



Skull much as in sharpei, but the bullae appear to be slightly 

 larger. 



Dimensions of the type, taken in flesh : — 



Head and body 722 mm. ; tail 76 ; hind foot, without hoof 195 ; 

 ear 89. 



Skull — greatest length 126 mm.; basal length 112; greatest 

 breadth 64; nasals 35 and 15; muzzle to orbit 59; muzzle to 

 front of mp^ 30. 



Horns, length 38 mm. ; diameter at base 12. 



Type. Immature male. B.M. no. 5.12.9.81. Original number 

 1279. Collected 10 August, 1905.

The discovery of the peculiar Nyasan Steinbuck Raphicerus 

 sharpei south of the Zambezi makes an important addition to the 

 known fauna of S. Africa. Possibly it has been obtained before, 

 but sportsmen might easily have confounded it with the Grysbok, 

 which it resembles by its hoary-mixed coat, though its short 

 horns, even when adult, and the absence of supplementa.ry hoofs, 

 show that it is really quite distinct from that animal. 



The British Museura owes to the kindness of Col. Manning 

 sevei'al specimens of R. sharpei from Iilpimbi, Nyasa, and these, 

 though fully adult, are so uniformly smaller than the two obtained 

 by Mr. Grant, that we think it advisable to give a subspecific name 

 to the Transvaal form.

Similar to the East African Steinbuck in all respects, except 

 that the bullfe are very markedly larger, and the nasals ai'e rather 

 smaller and narrower. 



Dimensions of the type, measured in the flesh : — • 



Head and body 814 mm. ; tail 65 ; hind foot 236 ; ear 102. 

 Fore-hoofs, length anteriorly 26-5, transverse breadth 19. 



Skull — greatest length 147 mm.; basal length 128; zygomatic 

 breadth 72*5; nasals 43x17; muzzle to orbit 71; muzzle to 

 anterior premolar 36 ; palatal length 74 ; length of upper molar 

 series (alveoli) 45 ; bullae, greatest diameter on inflated part 24'5, 

 height below level of glenoid surface 20, greatest breadth between 

 inflated parts of opposite sides 49*5.
