CROCIDURA FUMOSA SCHISTACEA Osgood. 



1910. Civcidura fumosa schistacca Osgood, Field Mus., Zool. Ser., vol. 10, No. 3, 

 p. 20. April 7. (Ulukenia HilIs=Lukenya Mountains, British East 

 Africa; type in F'ield Mus. Nat. ITist.) 



Specimens. — Five, from the following localities: 



British East Africa: Kapiti Plains, 3 (Loring); Ulukenia Hills, 

 2 (Loring). 



A female collected by Loring on the Kapiti Plains, May 7, contained 

 six small embryos; one from Ulukenia Hills, November 25, contained 

 five embryos, each about 8 miEimeters in length. 



The type-specimen of this shrew, which has been lent me by the 

 Field Museum of Natural Histoiy, Chicago, is slightly larger than any 

 specimen in our small series. Tlie form is mainly differentiated from 

 Crocidura fumosa fumosa by its grayish, less brownish color; but it 

 averages larger, with larger and heavier skull, and there is usually a 

 less conspicuous difference in the size of the second and third unicuspid 

 teeth. I mistrust that this is the species described by Dollman in 1915 

 as Crocidura luna umhrosa,^ t}'pe-locality Machakos. There seems to 

 be no reason to separate the two from the description, and Dollman 

 evidently had no specimens which he referred to scMstacea when pre- 

 paring his synopsis of the forms of Crocidura. 



For measurements of specimens of the subspecies of C. fumosa see 

 table, pages 56-58. 



CROCIDURA FUMOSA SELINA Dollman. 



1915. [Croddura]/. selina Dollman, Ann. and Mag. Nat. Hist., ser. 8, vol. 15, p. 



510. May. (Mabiri Forest, Chagwe, Uganda; type in British Museum.) 

 1915. Crocidura fumosa selina Dollman, Ann. and Mag. Nat. Hist., ser. 8, vol. 16, 



p. 371. October. 



Specimens. — Seventeen, from localities as follows: 



Uganda: Kampala, 3 in alcohol (Heller, Loring); Kisimbiri, 1 

 (Loring) . 



British East Africa: Kaimosi, 13 (Heller). 



Heller records one female with one embryo and one with three at 

 Kaimosi, January 27 and 28. 



This subspecies is well differentiated from true fumosa and from 

 scJiistacea by its darker, more blackish coloration and larger skull. 

 Although its range extends eastward along the north shore of Victoria 

 Nyanza to Kaimosi, specimens from the upper Nzoia River on the 

 Guas Ngishu Plateau are clearly referable to typical /wwosa.
