In addition to the lype Mr. Neave collected four specimens 

 of Lophuromys at Mporokoso, south of Lake Tanganyika, all 

 four being very similar in colour to the Katanga specimen. 



This species would appear to be more nearly allied to the 

 Aberdare form, L. zena, Dollm., than to L. aquilus, True, 

 from which it is readily distinguished by the entire upper 

 surface being finely speckled with pinkish buff. L. zena is 

 rather more coarsely speckled, and the general colour of the 

 upper and lower surfaces a good deal paler. 



It is probable that when this genus is more fully known it 

 may be thought necessary to reduce this form to subspecific 

 rank. For the present, however, it is more convenient to 

 regard it as a distinct species, since the relations of the other 

 forms are not yet satisfactorily determined.
