haired than in the allied species. Tail shorter than usual, 

 drab, ticked with hoary. 



Skull with small narrow nasals and comparatively slender 

 postorbital processes. Bullae much swollen both in front 

 and behind. Teeth larger than in P. ibeanus, not so large 

 as in P. edwardsi ; anterior molar (m 1 ) smaller than m 2 ; 

 m* unusually large, little smaller than m 2 and fully as 

 large as m 1 . Small lower premolars low, not exceeding m 1 

 in height, barely half the height of the caniniform premolar. 

 J/ 3 as large as m^

Type. Young adult female. Original number 24. Col- 

 lected 28th April, 1910, by the Rev. H. M. Whiteside. 



This Potto shows a relationship to the British East- 

 African P. ibeanus by the presence of the hoary-tipped hairs 

 in its dorsal fur, though these are not nearly so numerous as 

 in the more eastern species. The proportionally large size of 

 its posterior molar, above and below, is peculiar to itself. 



Crocidura spurrelli, sp. n. 



A large grey species, with a very narrow skull. 



Size large, rather less than in G. manni. Fur short, close, 

 and velvety; hairs of back about 4 mm. in length. General 

 colour above rather browner than Ridgway's " mouse-orey." 

 Under surface but little lighter, not defined laterally. * A 

 small lateral gland present in female. Hands and feet 

 greyish brown. Tail blackish, nearly naked above, the fine 

 hairs unusually long, but sparsely scattered, more closely set 

 below ; longer bristles fairly numerous. 



Skull long, unusually narrow ; lambdoid crest well deve- 

 loped, the lambdon projecting above the low sagittal crest. 

 Bony palate, as in C. manni, produced some little distance 

 behind the molars. As a result, the length of the meso- 

 pterygoid fossa is reduced, being no longer than in many far 

 smaller species; it is also unusually narrow, especially in its 

 posterior half. 



Dimensions of the type (measured in the flesh) : — 



Head and body 115 mm.; tail 70; hind foot (s. u.) 19; 

 ear 11. 



Skull : condylo-incisive length 29*6 ; basal length 26'3 ;
