1901.] MAMMAL8 FROM UGANDA. 89 



CEPHALOPHUS JOHNSTONI, sp. H. 



Most closely allied to C. iveynsi Thos. 1 , but fur thicker and 

 woollier, and general colour very much darker. 



Size, so far as can be judged from a young specimen, about as 

 in C. weynsi. Hairs of middle line of nape reversed forwards 

 as in that species. 



Forehead grizzled blackish brown ; coronal tufts uniform chest- 

 nut rufous (rather darker than Ridgway's " hazel"). Cheeks paler 

 brown. Anteorbital region dull buffy ; an inconspicuous buffy- 

 orange supraorbital streak present. Outer side of ears blackish 

 brown. Neck and fore-quarters shining brown, gradually redden- 

 ing posteriorly until the whole rump and hind-quarters are a deep 

 reddish russet ; middle line of back not markedly darker than 

 sides. Belly dull brownish. Fore limbs brown, darkening termi- 

 nally to black on the fetlocks ; hind limbs reddish to the hocks, 

 then brown darkening to black. Tail black along its upper surface 

 and white below. 



Owing to the youth of the type, the only dimensions worth 

 giving are : — Hind foot, including hoof, 205 ; ear (contracted) 65. 

 Combined length of three milk-premolars 29. 



This species is related on the one side to C. iveynsi Thos., of the 

 Congo, and on the other to C. spadix True, of Mt. Kilima-njaro. 

 From the former, of which one of the co-types is of just similar 

 age to the present specimen, it differs by its much thicker fur 

 and darker colour, being dark brown and dark rufous as compared 

 with pale brown and pale rufous ; it shares, however, with C. iveynsi 

 the characteristic reversal of the nuchal hairs. From C. spadix, 

 on the other hand, it differs by this reversal of the hairs, that 

 species having the neck-hairs all directed backwards, and also by 

 the more rufous colour of the posterior back, for Mr. Miller tells 

 me that the general colour of C. spadix is " Prouts brown, 

 darkening to nearly black along spine and on rump, buttocks, and 

 tail." The coronal tufts of O. spadix are partly black, and the 

 tail is only whitish at the tip, not throughout its length below. 



Hab. Toro, east of Kuwenzori. 



Type. Young female. B.M. No. 1.8.9.64. July 1900. 



CEPHALOPHUS BUBLDUS, sp. 11. 



Fur thick, close and slightly woolly. General colour of 

 neck and body uniform rich chestnut-rufous, something between 

 " hazel " and " cinnamon-rufous " of Bidgway, but brighter and 

 richer than either ; bases of the hairs rather greyer, and along 

 the middle line of the back, especially posteriorly, these greyer 

 bases are more decidedly grey-brown, and, showing through, give a 

 darker hue to the dorsal line. Hairs of neck directed backwards 

 as usual. Middle line of nape rather browner, probably in 

 continuation of a darker area on the head. Sides of neck particu- 

 larly bright rufous. Under surface paler rufous, not sharply 



' Described lor the Belgian Congo Museum, and now in the press. Co-types
