On Two new Duikers from Mt. Elgon. 273 



They thus differ markedly in scale-structure from the type 

 species (St. fascial a, F.), and should, I believe, be erected 

 into a new genus if scale-structure be regarded as of generic 

 value. 



XXXVII. — Two new Duikers related to Cephalophus 

 abyssinicus and a new Dendromus/rom Mt. Elgon. By 

 E. C. Wroughton. 



The Natural History Museum has recently received two 

 specimens of a Duiker from the Gwas Nyisha Plateau, B. E. A. 

 Tliese specimens, a male and a female, collected and presented 

 by Mr. F. C. Selous and Major Horsburgh respectively, prove, 

 on comparison with the material already in the National 

 Collection, to be indistinguishable from C. abyssinicus nyansce 

 of Neumann. The reduction in girth of the horn at the base 

 and its compression antero-externally into a ridge is fairly 

 constant amongst these Duikers, but Mr. Selous's buck shows 

 these characters to an exaggerated extent. On laying out the 

 specimens for this comparison, however, it became evident 

 that the Duiker of the Kenya District is a well-marked 

 geographical race. 



Cephalophus abyssinicus hindei, subsp. n. 



A Duiker of the northern short-eared section of the grimmii 

 group, distinguished by its brighter colouring. 



Size about the same as nyansce. General colour above 

 tawny ochraceous, bright on the neck and shoulders, duller on 

 the back and loins, but the yellow tinge is never absent, even 

 on the rump, as it is in nyansce; individual hairs of the neck 

 drab-grey, with ochraceous tips ; more posteriorly the ochra- 

 ceous tip becomes a subapical ring, and the tip is black. 

 Below, the chin and the insides of the upper part of the limbs 

 whitish ; throat ochraceous buff, the hairs the same colour in 

 their whole length ; the abdomen towards the flanks coloured 

 like the neck, fading to buffy white in the centre, the hairs 

 with pale drab bases. 



Skull of the same size as in the more western race. 



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

 men) : — 



Head and body 825 mm. ; tail 100; hind foot 225; ear 95. 



Skull : greatest length 160 ; greatest breadth 72 ; nasals 61 ; 

 muzzle in front of p" 46 ; palate 76 ; upper tooth-row 52 ; 

 length of upper molars 2b'0 ; bullae 21'5.
