 Mr. A. Blaney Percival on the 9th of January, 1911, and

 Earmgo. 



Allied to X. dahagala stephanicus, Thos., from which it is 

 distinguished by its much darker dorsal surface. 



Size and general proportions as in the other members of 

 this group. General colour of back dark olive, speckled with 

 yellow and white, the general effect much darker than in 

 stephanicus. Top of head black, speckled with pale buff and 

 orange, rather darker than rest of dorsal surface and 

 markedly different from the brownish head of stephanicus. 



Orange rufous on nose and colouring of face much as in 

 stephanicus. Flanks richer and darker, the black speckling 

 rather more evident. Limbs, ventral surface, and tail similar 

 to those of X. d. stephanicus. 



Skull much as in X stephanicus, broader across inter- 

 orbital region ; auditory bullae less inflated.

 Head and body 239 mm. ; tail 192; hind foot 55*5; 

 ear 12. 



Skull : greatest length 54'5 ; basilar length 40"5 ; condylo-

 number 1376. Collected in October 1910. 



This form, though evidently closely related to X. d. ste- 

 phanicus, is readily recognized by the dark olive coloration of 

 the dorsal surface and the blackish area on the top of the 

 head. The rufous patch on the muzzle is similar to that of 

 stephanicus and therefore renders this Baringo form easilv
