IJiifoi tiinately only one specimen of this fine species was 

 ohiained hy the e.xpedition, and that was jneserved in Sj)irit. 

 However, its longer tkidl, larger teeth, longer fur, and the 

 slaty niixture of its belly-colour will readily distinguish it 

 from 7/i. rudluns, to which alone it is nearly allied.

Hah. Jiuwenzori East. Alt. C00j'-7000'. 



Tyi>e. Adult female. B.M. no. G. 7. 1 . 136. Original 

 num'ber 207. Collected SOlh December, 190r>, by D. Car- 

 ruthcrs. Nine specimens, of which six are females, including 

 one in spirit. 



The presence of only four niammaj in this nioupo is a very 

 curious fact, as there are six in all the other members of the 

 Til. dcUc/iurus group, even those from compaiatively near 

 localities. Specimens from tShoa (Zop/iiro), ^It. Elgf>n 

 [Jack.sou), Nyasa {Johnston), Angola {Ansorgi)^ and South 

 Africa all show this latter number.
