 dral), ticked with hoary.

 m' unusually lar^^e, little smaller than m' and fully as 

 large as nt^. Small lower premolars low, not exceeding njj 

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

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

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



'i'his Potto shows a relationship to the British East- 

 African P. ihpanus 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 spurreUij sp. n. 



A large grey species, with a very narrow skull. 



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

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

 colour above rather browner than Ridgway's " mouse-f^rey." 

 Under surface but little lighter, not defined laterally. A 

 sniall 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. 

 Bimy palate, as in C. maiitii, 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 llonini.; tail 70; hind foot (s. u.) 19 ; 

 ear 11. 



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