Mammals from the Upper Congo. 471 



Skull decidedly smaller than in S. somereni, the specimen 

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

 is greater than occurs within any of the series of African 

 CrocidurcB recently published by Mr. 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 143 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 i l to 

 tip of p* 7-2; front of^> 4 to back of m 2 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 was first placed, are as marked in S. congicus as in 

 the typical form, no approximation to Sylvisorex being- 

 perceptible.

 of these specimens.
