three forms will eventually bo found to intergrade, and that all may 

 prove to be subspecies of Crocidura fulvaster (Sundevall).^ In fact, 

 I can not distinguish specimens of lutreUa from the description of 

 fulvaster, and would not be surprised if the two names referred to 

 the same form. The type-locality of fulvaster is on the Bahr el 

 Abiad (WMte Nile). This locahty is some distance from the region 

 where lutrella was collected, and I do not feel justified in treating 

 the two names as synonyms without specimens oi fulvaster iov actual 

 comparison. Dollman placed fulvaster among his midetermined 

 species, 2 but suggests its identity with C. sericea SundevaU, a mem- 

 ber of the hindei group.

CROCIDURA PARVIPES PARVffES Osgood. 



1910. Crocidura jmrvipes Osgood, Field Mus., Zool. Ser., vol. 10, No. 3, p. 19. 

 April 7. (Voi, British East Africa; type is Field Mus. Nat. Hist.) 



Specimen. — One in alcohol from — 



British East Africa: Fort HaU (Loring). 



This specimen, though clearly referable to C. parvipes parvipes, 

 is somewhat intermediate in characters between true parvipes and 

 C. p. nisa. 



In Dollman' s monograph of the African species of Crocidura this 

 species is placed in the jacTcsoni group. The type-specimen, which 

 I have before me, thanks to the authorities of the Field Museum, 

 shows clearly that the "species is not closely related to jacTcsoni, but 

 belongs in a section of the hindei group containing the three small 

 forms, lutrella, parvipes, and nisa. 



CROCIDURA PARVIPES NISA Hollister.

1916. Crocidura parvipes 7iisa Hollister, Smitlisonian Misc. Coll., vol. 66, No. 

 8, p. 2. May. (Kibabe, Kisumu, British East Africa; type in U. S. 

 Nat. Mus.) 



Specimen. — One from — 



British East Africa: Eababe (HeUer). 



The type-specimen, collected January 20, contained five embryos. 

 This shrew is close to Crocidura parvipes Osgood. It is somewhat 

 darker in color than the type of parvipes and very much darker 

 than any skin in the series of 11 specimens of C. lutrella of Lado. 

 The single specimen in om' collection which I have referred to Cro- 

 cidura parvipes parvipes is clearly intermediate between parvipes 

 and nisa.
