April, 1910. New East African Mammals — Osgood. 21 



Field Museum of Natural History. Adult female. Collected Decem- 

 ber 15, 1905, by E. Heller. 



Characters. Similar to C. fumosa but paler and less brownish in 

 color especially on the underparts. Upperparts in fresh pelage dark 

 mouse gray with a little light silvery ticking; underparts paler, the 

 basal color slate color to blackish slate instead of slate black, the tips 

 very pale broccoli brown, much paler than in fumosa; feet averaging 

 considerably paler; tail decidedly more distinctly bicolor (in fumosa 

 as a rule the tail is practically all dark or at most only very slightly 

 lighter below). 



Measurements. Type: Total length 145; head and dody 93; 

 tail vertebrae 52 ; hind foot (c. u.) 15. Skull of type: Greatest length 

 23-1 ; zygomatic breadth 10. i; postpalatal length 10.6; length of 

 toothrow 10.2. 



Remarks. This is in general a bluish gray shrew while true fumosa 

 is a dark brownish one almost as dark below as above. Specimens 

 from Nairobi tend more or less toward the new form but appear to be 

 referable to fumosa.
