underparts more distinctly marked off from the brownish 

 tint of the dorsal surface. 



Heller describes the coloration as follows : — " Dorsal 

 colour broccoli-brown, the colour uniform to lower sides, 

 where it is fairly well defined against the light grey under- 

 parts ; hair everywhere plumbeous at base ; feet white ; ears 

 drab ; tail indistinctly bicolor, broccoli-brown above, drab- 

 gi*ey below." In the Museum Collection is a specimen 

 from Baringo which undoubtedly represents this race. The 

 colour of this individual is rather brighter than in true 

 hildegardece, the dorsal surface being rather more cinnamon, 

 near "snuff-brown" speckled with "neutral grey." The 

 cold light grey belly is considerably more sharply differen- 

 tiated from the brown dorsal surface than in the Fort Hall 

 form. Backs of hands and feet dirty white. Tail rather 

 paler below than in hildegardece, but not nearly as light as in 

 the Uganda race. 



Skull a trifle larger, with rather larger teeth, but of the 

 same flattened type; in the Baringo specimen the brain- 

 case is rather broader than in hildegardece. 



Dimensions of the type (as given by Heller) : — 



Head and body 72 mm. ; tail 51 ; hind foot 12. 



Skull : condylo-incisive length 20 ; greatest breadth 9 ; 

 length of upper tooth-row 88. 



Skull-dimensions of a female from Baringo : — 



Condylo-incisive length 20*5 mm. ; greatest breadth 9*5 ; 

 least interorbital breadth 4*2 ; length of palate 8'4 ; post- 

 palatal length 9*8 ; greatest maxillary breadth 6*5 ; median 

 depth of brain-case 48; length of upper tooth-row 8*4. 



Hab. Mt. Lololokui, Northern Guaso Nyiro District, 

 British East Africa. Altitude 6000 feet. 



Type. Adult female. U.S. Nat. Mus. no. 181820. 



The rather lighter coloration, more distinctly differentiated 

 ventral and dorsal surfaces, and rather larger teeth separate 

 this race from hildegardece. The lighter colour, less bicolored 

 tail, and rather larger skull separate it from the Uganda 

 race described below. 



(97) Crocidura hildegardece rubecula, subsp. n. 



Very like true hildegardece, but with lighter underparts 

 and more hairy and more distinctly bicolor tail. 



General colour of dorsal surface of new pelage dark 

 brown (between "mummy-brown" and "sepia"); in the
