 July 22. (West slope of Mt. Kenia at 10,000 feet, British East Africa: 

 type in U. S. Nat. Mus.) 



Specimens. — Twenty-two, including seven in alcohol, from — 

 British East Africa: Mt. Kenia (Loring, Mearns). 

 This brown pygmy shi-ew is related to the Naivasha alUx and the 

 two forms are externally very much alike. The Kenia form has a 

 slightly smaller skull and noticeably smaller first upper unicuspid 

 tooth. Mearns found foui- fetuses in a female collected September 

 29 at 10,000 feet altitude. Heller states: » 



The range of this .'species extends from 10,000 to 13,000 feet — that is, from the upper 

 limit of the bamboo forest to the lower part of the giant Senecio zone. Through most 

 of this extent it is associated with the giant Crocidura, C. nyansae, attaining, however, 

 a somewhat higher altitude than this species. 



Through an unfortunate accident in the photograph studio, the 

 type skull of Crocidura alpina was badly damaged after the pictures 

 shown on Plate 10 were made.

Externally tliis unique ty]3e- -specimen resembles greatly certain 

 specimens of Crocidura Mldegardex, but its long tail and peculiar 

 skull and teeth readily distinguish it. The small size of the claw.s 

 and the elongated occiput are so closely approached in other species 

 that they become purely relative characters and can liardly be con- 

 sidered generic. An even better specific character is found in the 

 last upper unicuspid. This tooth in C. rooseveUi differs from all 

 African species of Crocidura which I have seen in the relatively 

 large size of the cone and small cingulum shelves, especially the 

 exterior. The difference is almost exactly that between two com- 

 mon Eiu-opean species, C. russula and C. leucodon, though somewhat 

 more pronounced in the African species.
