 evenly narrow throughout, not broadening posteriorly as in 

 D. BentJey(f. Bull* decidedly larger than in that species. 



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



Head and body 143 mm. ; tail 128 ; hind foot 28-5 ; ear 19. 



Skull: greatest length 34*3; basilar length 30; greatest 

 breadth 18*5; length of nasals 12 ; diastema 10'3; palatihir

Type. Female. B.M. no. 6. 7. 1. 75. Original number 33. 

 Collected 16th January, 1906, by R. E. Dent. 



No species of J)asijmijs have been iiitherto described from 

 this part of Africa, the nearest being the Lower Congo 

 D. Benilei/ce, from which the present animal differs by the 

 characters above mentioned. From the D. montanus of the 

 higher altitudes of Ruwenzori it is, of course, at once distin- 

 guishable by its shorter coarser fur and much longer tail.
