Specimens. — Two, from — 



British East Africa: Lakiundu River (Heller). 



The shrew described by Osgood as Crocidura xantippe,^ typc- 

 locaUty Voi, was placed by Dollman in the jacJcsorvi group, but it is 

 not closely related to jachsoni or its allies, and agrees with the mem- 

 bers of the Jiindei-JiscJieri group in all essential characters — colora- 

 tion; the long narrow rostrum; strong, wide maxillary processes; 

 narrow posterior border of the bony palate; and the enlarged first 

 upper unicuspid. It is in fact very closely related to Crocidura 

 percivali, but is larger and lighter colored, with larger skull and teeth. 

 Another East African shrew not represented in the National Museum 

 collection is Crocidura voi Osgood.- Wliile not closely related to 

 any species known to me, it has, nevertheless, many decided char- 

 acteristics of the liindei group, but differs in its slaty coloration, 

 short, hght-colored tail, and massive dentition. The type-speci- 

 mens of C. xantippe and C. voi have been lent me by the Field Museum 

 of Natural History, Chicago, in connection with this work.

1912. Crocidura suahelse Heller, Smithsonian Misc. Coll., vol. 60, No. 12, p. 6. 

 November 4. (Mazeras, British East Africa; type iu U. S. Nat. Mus.) 



Specimens.— Twenty-^ye, from localities as follows: 

 British East Africa : Changamwe, 1 (Mearns); Mazoras. 24, iu- 

 cludiiig 3 in alcohol (Heller). 



This pale coast species is, following Dolhnan, here placed in the 

 fischeri group, although it and its two allies (simiolus and mutesx) 

 certainly show many characteristics of the mjansse, groiip^, some 

 species of which it approaches in size. It is only slightly smaller than 

 C. sururse of Lado. The two smaller upper iinicuspids are virtually 

 of the same size, and either the second or the third may, in certaiii 

 specimens, appear the larger. No specimen in the series shows 

 anything approacliing the relatively smaller third upper unicuspid 

 as in the type of Crocidura voi, where the difference is very pro- 

 nounced, the second being nearly twice the size of the third.
