belonging to the Genus Crociduva. 127 



shrew is considerably darker than butleri, resembling more 

 the Cliarnia River species, beta, described above, but with 

 less definition between the brown upper parts and greyish- 

 Avhite belly. Backs of hands and feet dirty white. Tail 

 very thick at base, longer than in butleri, brownish above, 

 white below ; bristle-hairs not numerous, white. 



Skull a little smaller than that of butleri. Tooth-row 

 shorter, teeth rather narrower, the second and third upper 

 unicuspids smaller and more oval in transverse section, 

 third slightly overlapping second, but not so crushed together 

 as in smithi nor hidden externally by the anterior cusp of 

 the large premolar.

Head and body 84- mm. ; tail 47 ; hind foot 12'5 ; 

 ear 11.

Type. Adult male. B.M. no. 12. 7. 1. 61. Original num- 

 ber 875. Collected on October 8th, 1911, by A. Blayney 

 Percival, Esq., and presented by him to the National 

 Collection. 



The longer tail, darker colour, and. smaller teeth separate 

 this species from the Bahr-el-Ghazal butleri. 



It is with pleasure that I name this new form after 

 Mr. Blayney Percival, the collector and donor, to whose 

 generosity the Museum is greatly indebted.
