heloriging to the Genus Crocidura. 129 



Dental characters the same as in voi, the unicuspids 

 crushed together. 



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



Head and body 110 mm. ; tail 69; hind foot 16. 



Skull : condylo-ineisive length 26*5 ; greatest breadth 

 10*5 ; interorbital width 4-8 ; length of upper tooth-row 11'8. 



Hub. Mazeras, British East Afrira. 



Type. Adult male. U.S. Nat. Mus. no. 181815. 



The larger dimensions and browner colour distinguish this 

 shrew from the Voi species. Crocidura fischeri, although 

 possessing a skull nearly equal in lengthy has a much shorter 

 tail and lighter underparts.

This form is distinguished at once by its very pale smoke- 

 grev upperpartSj white flanks, limbs, belly, and tail, and flat 

 skull. 



Size medium, hind foot from 11 to 12*5 mm. in length. 

 Fur rather short, hairs of back 3 to 4 mm. in length. 



Colour pale smoke-grey above, faintly tinged with pale 

 cinnamon, the general eff'ect about as in ''pale neutral 

 grey" sprinkled with "light drab." Flanks almost pure 

 white, the grey hair-bases considerably less evident than on 

 the back. Belly white, hairs white almost to the roots, 

 only the extreme bases pale grey. Lateral gland small, 

 marked by a streak of short white hairs. Backs of hands 

 and feet white. Tail rather short, covered with short white 

 hairs al)ove and below ; bristle-hairs fairly numerous, evenly- 

 distributed over nearly the whole length of the tail, white in 

 colour, but very slender and inconspicuous. 



Skull smaller than \n fischeri, brain-case very flat, recalling 

 the flattened skulls of the Jdldegardea group ; interorbital 

 region more parallel-sided than in hindei, the posterior inter- 

 orbital breadth rather narrower than usual. Teeth fairly 

 large, especially the second upper incisors ; small upper 

 unicuspids crushed closely together, the third partially 

 hidden externally by the small anterior cusp of the large 

 premolar, the cusp of the second is slightly longer vertically 

 than that of the thii'd, but otherwise the two teeth are 

 almost equal in size. Last upper molar small and narrow. 



Dimensions of the type (in spirit) : — 



Head and body 64 turn. ; tail 31 ; hind foot 11 ; ear 7*5. 

 , Skull: coudylo-incisive length 20*8; greatest breadth 9 ;
