Mammals from the Upper Congo. 471 



Skull decidedly smaller than in S. somereyii^ the specimen 

 being a male and that of somereni a female ; the difFcrence 

 is greater than occurs within any of the series of African 

 Crocidxira; recently published by ]\lr. Dollman. Lambdoid 

 crests not projecting backwards beyond the level of the 

 condyles. Teeth essentially similar, but the last upper uni- 

 cuspid rather smaller in proportion. 



Dimensions (measured in flesh) : — 



Head and body 14:3 mm. ; tail 77 ; hind foot 20; ear 10. 



Skull : condylo-incisive length 31'3 ; condylo-basal length 

 30*2 ; greatest breadth 13*2 ; anterior breadth across palate 

 9'6; palatal length 14; upper tooth-row 13'6; tip of ? to 

 tip of p* 7'2; front of ^j* to back of in^ 6*4 (in somereni 7"5) ; 

 lower tooth-row 12* 7. 



This shrew differs from its Uganda ally mainly by its 

 smaller size and smaller teeth. The type of -S'. somereni was 

 hitherto the only specimen of the genus known, so that this 

 second example is of much value. The generic characters 

 used to distinguish Scutisorex from Sylvisorex, in which 

 somereni yir&.s, first placed, are as marked in S. congiciis as in 

 the typical form, no approximation to Sylvisorex being 

 perceptible.

This dark form was first obtained by Mr. Robin Kemp in 

 Southern Uganda, but was only distinguished on the arrival 

 of these specimens.
