NO. 9 NEW SPECIES OF EAST AFRICAN MAMMALS — HEELER 5 



CROCIDURA ALPINA, new species 



Type from the west slope of Alt. Keiiia, altitude io,000 ft., Brit- 

 ish East Africa; adult female; number 163089, U. S. Nat. Mus. ; 

 •collected b\- J. A. Loring-, October 4, 1909 ; original number 7728. 



Coloration. — Dorsal coloration Prout brown, changing on lower 

 sides gradually to the bufify gray of the under parts. Feet lighter, 

 wood brown. Tail above like back ; below light huffy, but tiot 

 sharply bicolor. 



Measurements. — Head and body, 65 mm.; tail, 3<); hind foot, 11. 

 Skull : condylo-incisive length, 16.2 ; breadth of brain-case, 7.5 ; 

 depth of skull at bullse, 4.6 ; length of upper toothrow, 7. 



This species is closely allied to allex, from which it may be dis- 

 tinguished by its much flatter skull (one-half millimeter less), rela- 

 tively small upper middle incisor, and by its bicolor tail and lighter 

 coloration generally. 



It is surprising to find this pygmy shrew in the alpine region of 

 Kenia. The closely allied aUe.v inhabits the lake district of Nai- 

 vasha, the intermediate region about the base of Kenia being in- 

 habited by the much larger hildegardece. The range of this species 

 extends from 10,000 to 13,700 ft. — 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 Croci- 

 dura. C. nyanscc, attaining, however, a somewhat higher altitude 

 than this species. I
