274 On Iwo new Duikers from Alt. Elgon. 



Bab. Kenya District, B. E. A. (Type from Fort Hall.) 

 Type. Young male. B.M. no. 4. 12. 6. 11. Collected and 

 presented to the Natural History Museum by Mr. S. L. 

 Hinde. 



The type is a young male in milk-dentition with a fine coat. ' 

 The following are similar skull-measurements of an old 

 male (skin mutilated) collected by Mr. Hinde at Nyeri, 

 Kenya District, as compared with those (in brackets) of 

 Mr. Selous's specimen of nyansce, which is about the same 

 age:— 



Greatest length 159 (161) mm.; greatest breadth 76 (72) ; 

 nasals 51*5 (51); muzzle in front of p* 50 (48); palate 

 74 (76) ; upper tooth-row 44 (49) ; length of upper molars 

 26(28); bullae 21 (24). 



Typical long-eared (110-125 mm.) G. grimmii occupies 

 the whole of S. Africa, where it has received many names. 

 At its northernmost limit, on the west, is G. splendidulus, 

 Gray, from Angola ; further east, the Matabili form is 

 fulvescenn, Lorenz, which probably crosses the Z imbesi into 

 Northern Rhodesia; the eastern representative is alt if ro us, 

 Peters {=oculuris, Pet.), from Southern Mozambique, which, 

 as shown by specimens in this Museum, ranges south of the 

 Zambezi to Tette and north of it to the Loangwa River, as 

 far north at least as S. Angoniland. A series, however, in 

 the National Collection from the Shire Highlands belongs to 

 the northern, short-eared, abyssinicus section ; it is so 

 markedly different from any of the forms mentioned above, 

 that it seems worthy to be ranked as a distinct geographical 

 race. 1 propose to call it 



Ceplialophus abyssinicus shirensis, subsp. n. 



A Duiker of the short-eared section of the grimmii group, 

 distinguishable by its pale, bright ochraceous colouring. 



Size about the same as in the East Afiican races. General 

 colour above ochraceous buff; all iiairs with drab bases, those 

 of the neck and shoulders ochraceous buff to their tips, those 

 of the back shortly tipped with black. Colouring below as in 

 hindeiy but in a much paler shade. 



Skull as in hindei. 



Dimensions of the type (approximate, from a dry speci- 

 men) : — 



Head and body 950 mm.; tail 100; hind foot 250 ; ear 90. 



Skull : greatest length 164 ; greatest breadth 76 ; nasals 55 ;
