heloiKjing to the Genus Crocidura. 375 



This Zanzibar shrew would appear to be considerably 

 larger than bicolor and the allied races ; in general body- 

 dimensions it is more as in parvipes from Voi ; probably it 

 is more nearly allied to this form than to bicolor, and is here 

 treated as a separate species.

Crocidura xantippe, Osgood, Field Mus. Nat. Hist., Publication 143 

 (Zool. Ser.), vol. x. no. 3, p. 19 (1910;. 



Size rather larger than mjacksoni. 



Colour above "fawn-colour with a fine vermiculation of 

 lighter (almost ecru-drab) *' ; ventral surface dull greyish 

 Avhite. Backs of hands and feet white. Tail dusky brown 

 above, below whitish for proximal two-thirds, dusky for 

 terminal third. 



In the Museum Collection are four specimens, two from 

 Voi and two from Taveta, which I have accepted as repre- 

 senting this species. They are rather darker in colour than 

 Osgood's type, but very similar iu dimensions. 



Skull rather longer than in jacksoni, brain- case larger. 

 Small upper unicuspids almost equal, second a trifle smaller 

 than third. 



Dimensions of the type (as given by Osgood) : — 



Head and body 90 mm. ; tail 60; hind foot 15. 



Skull : condylo-iucisive length 22 ; maxillary width 6*8 ; 

 length of upper tooth-row 9"6. 



Hab. Voi, British East Africa. 



Type. Adult male. Field Museum Xat. Hist. no. 16888. 



Distinguished from jacksoni by its paler and more fawn- 

 coloured pelage. 



The original spelling of the specific name is presumably a 

 misprint.
