:U0 Mr. O. Thomas on 



I can find no difference between tliis series and tlie four 

 examples in the Museuni from Barin^i^o, so that tlie species is 

 evidently widely distributed through British East Africa. 

 It is nearly allied to E. pulcher fioiu Usanibiro. 



The sjiecies from the Athi plains which I described as 

 MacrosceHdes delamerei -proves to be a member of the restricted 

 genus A^asilio. 



12. Crocidura monax, sp. n. 



(?. 1161,1176,1178,1185,1201; ?. 1161,1177,1183. 

 Kombo. 



Size large, colour dark, tail nearly without bristles. 



Size about as in C. turha, 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 aud fumostiy 

 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. turha. 



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



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



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

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

 between outer corners of m^ 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.fiimosa is smaWav 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
