I can find no difference between this series and the four 

 examples in the Museum from Baringo, so that the species is 

 evidently widely distributed through British East Africa. 

 It is nearly allied to E. pulcher from Usatnbiro. 



The species from the Athi plains which I described as 

 MacrosceHdes delamerei proves to be a member of the restricted 

 genus Nasilio.

 Rombo. 



Size large, colour dark, tail nearly without bristles. 



Size about as in C. turba, or rather larger. Fur thick, 

 close and woolly ; hairs on back 4"5-5'0 mm. in length. 

 General colour dark slaty, very much as in turba and fumosa, 

 scarcely lighter below. Ears, hands, feet, and tail uniform 

 dark brown. Tail longer than usual, slender, practically 

 without longer bristles, a few scattered ones present on the 

 basal third — in this respect like C. maurisca. 



Skull rather broader and flatter than in C. turba. 



Dimensions of the type (measured in the flesh) : — 



Head and body 88 mm.; tail 66; hind foot 16*2 ; ear 10. 



Skull : condylo-incisive length 24*3 ; basal length 20*8 ; 

 greatest breadth 10*8 ; upper tooth-series 10'9 ; breadth 

 between outer corners of m 2 7*2. 



Type. Old female. B.M. no. 10. 7. 2. 58. Original num- 

 ber 1161. Collected 11th June, 1910. 



The tail varies in length from 60 to 72 mm. 



This species is at once distinguishable by its almost bristle- 

 less tail, the only other East-African shrew agreeing with it 

 in this respect, C. maurisca, being very much smaller. 

 C. turba, the most like it in other ways, has its tail unusually 

 well covered with bristles. C.fumosais smaller and also has 

 a bristly tail. All other East-African species are wholly 

 different either in colour or proportions.

1 cannot determine these shrews satisfactorily at present. 

 Perhaps the larger one may prove to be referable to C. velu- 

 tina } Thos., though it is a little smaller and longer-tailed than
