EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 31 



Genus NASILIO Thomas and Schwann. 



1906. Nasilio Thomas and Schwann, Abstr. Proc. Zool. Soc. Loudon, No. 3S, 

 p. 10. June. (N. brachyrhynchus.) 



The lesser jumping shrews are widely distributed in East Africa, 

 and specimens were collected by members of the Smithsonian African 

 Expedition in many locaUties. The genus is known to occur in 

 Uganda, but no specimens from that region are in the collection. 



NASILIO BRACHYRHYNCH L'S DELAMEREI (Thomas). 



1901. Marcmscelidts delamerei Thomas, Ann. and Mag. Nat. Hist., ser. 7, vol. 8. 

 p. 155, August. (Athi River, British East Africa; type in British Mu- 

 seum.) 



1910. iVasilio brachyrhynchus delamerei Roossvei.t, African (jiame Trails, Amer. 

 ed., p. 474; London ed., p. 485. 



Specimens. — Twenty-seven, from the following localities: 

 British East Africa: Engare Narok River, 1 (Loring); Kapiti 

 Plains, 1 in alcohol (Loring); Loita Plains, 1 (Heller); Southern 

 Guaso Nyiro, 13, including 3 in alcohol (Loring, Heller); Ulukenia 

 Hills, 11, including 4 in alcohol (Loring). 



Loring records females from Ulukenia Hills pregnant as follows: 

 November 26, two with two embryos each; November 27, one with 

 one embryo; and from the Southern Guaso Nyiro, two large fetuses 

 each in females taken June 21 and 30. The specimens from Southern 

 Guaso Nyiro and Loita Plains seem to be identical in color with the 

 skins from Ulukenia Hills. 



NASILIO BRACHYRHYNCHUS ALBIVENTER Osgood. 



1910. Nasiiio brachyrhynchus albkenter Osgood, Field Mus., Zool. Ser., vol. 10, 

 No. 2, p. 13. February. (Lake Elmenteita, British East Africa; type 

 in Field Mus. Nat. Hist.) 



Specimens. — Six, from localities as follows : 



British East Africa: Bargunett River, Meru Road, 1 (Heller); 

 Engare Ndare River, 1 (Clark) ; Lesiweru River, Meru Road, 1 (Hel- 

 ler) ; Naivasha Station, 2 (Loring) ; Nyuki River, 1 in alcohol (Heller.) 



This is a shght color subspecies, apparently recognizable from 

 delamerei only by the average darker tones of the upperparts. The 

 Naivasha Lake skins, while nearest to albiventer, are clearly inter- 

 mediate tovv'^ard delamerei. Young examples of both subspecies are 

 usually considerably darker and richer colored than fully adult 

 animals.
