new African Mammals. 195 



Dimensions of the type (measured in flesh) : — 



Head and body 218 mm. ; tail 169; hind foot 45 ; ear 20. 



Skull : condylo-basal length 48 ; length of p 4 on outer 

 edge 4"3, greatest diameter 5*6. 



Hah. Southern Uganda. Type from Ketoma, Ankole. 

 Alt. 5000'. 



Type. Adult female. B.M. no. 3.11.7.14. Original 

 number 298. Collected May 1903 by W. G. Doggett and 

 presented by Col. C. Delme*-Radcliffe. Three specimens. 



This form represents an intermediate stage between the 

 distinctly buff H. victorina and the tawny II. u. rufala o£ 

 British East Africa. At the same time its colour seems to 

 be nearer that of the former than of the latter, and I there- 

 fore provisionally place it as a subspecies of victorina. 

 Curiously enough, this relationship is more strongly brought 

 out by artificial light than by daylight, victorina and ochracea 

 being then scarcely distinguishable, while the tawny rufula 

 shows up as a conspicuously different brownish animal. 



Crossarchus ansorgei, sp. n. 



Allied to C. obscurus, but considerably smaller. 



General colour above and below coarsely grizzled blackish, 

 as in C. obscurus, but with a strong tawny suffusion, the 

 light rings on the long hairs buffy, and the underfur broadly 

 tipped with tawny or tawny-ochraceous. Crown blackish. 

 Sides of neck dull ochraceous. Forearms and hands black. 

 Hind feet dull tawny proximally, black terminally. Tail 

 mixed tawny and black, more tawny proximally, black 

 terminally. 



Skull intermediate in size between those of C. obscurus 

 and C. dybowskii, its proportions about as in the latter, its 

 palate less produced than in the former. 



Dimensions of the type (measured in flesh) : — 



Head and body 320 mm.; tail 212; hind foot 60 ; ear 24. 



Skull : basal length 58 ; greatest breadth 33 ; interorbital 

 breadth 13; breadth of brain-case 25 - 7; palatal length 31 ; 

 front of canine to back of m 2 21. 



Hab. N. Angola. Type from Dalla Tando. Alt. 800 m. 



Type. Adult female. Original number 48. Collected 

 25th November, 1908, by Dr. W. J. Ansorge. 



Whether the comparatively tawny tone of this Crossarchus 

 will prove to be constant is, 1 think, doubtful, but it is in any 

 case readily recognizable by its size, in which respect it forms 

 an intermediate stage between G. obscurus and G. dybowskii. 

 The four species of this group thus form a series in order of
