CROCIDURA BICOLOR PLANICEPS Heller. 



Plate 10, figs. 3, 4. 



1910. Croddura planiceps Heller, Smith- 

 sonian Misc. Coll., vol. 56, No. 15, 

 p. 5. December 23. (Rhino 

 Oamp, Lado Enclave; type in U. 

 S. Nat. Mus.) 



Specimens. — Seven, from the fol- 

 lowing localities: 



Lado: Rhino Camp, 6, including 

 one in alcohol (Loring) , 



Uganda: Hoima, 1 (Lormg). 



This shrew shows close relationship 

 with C. h. elgonius, and is chiefly dis- 

 tinguished by its slightly larger size 

 and longer tail. The specimen from. 

 Hoima, Uganda, appears somewhat 

 intermediate, though plainly belong- 

 ing best with planiceps. There is a 

 remarkable variation in the relative 

 size of the second and third upper 

 unicuspids in this form. 



For measurements see page 66. 



CROCIDURA ALLEX ALLEX Osgood. 



1910. Croddura allex Osgood, Field Mus., 

 Zool. Ser., vol. 10, No. 3, p. 20. 

 April 7. (Naivasha, British East 

 Africa; type in Field Mus. Nat. 

 Hist.) 



1910. Croddura allex Roosevelt, African 

 Game Trails, Amer. ed., p. 480; 

 London ed., p. 491. 



Specimens. — Twelve, from the fol- 

 lowing localities: 



British East Africa: Aberdare 

 Range, 2 (Heller); Naivasha Station, 

 9, mcluding 3 in alcohol (Loring); 

 Oljoro O Nyon River, 1 (Heller). 



The specimens from the summit of 

 the Aberdare Range are decidedly 

 intermediate in characters between 

 allex and alpina, but on the whole go 

 best with the Naivasha specimens of 

 aUex.
