The Collection also includes a dried skin and skull of an indivi- 

 dual from the Cataract of the Nile, which appears to be intermediate 

 between this species and N. limbatus ; but it is considerably larger 

 than either, and the colour of the fur and the dentition are slightly 

 different. The form of the muzzle, however, is so much distorted 

 by the removal of the skull that I hesitate to describe.it as the type 

 of a new species. 



Ears circular, united by a deep band, the upper margin of which 

 is convex, and probably in the recent specimen much larger than in 

 N. pumilits ; tragus as in that species, but the antitragus has a much 

 broader base and is altogether larger. 



Fur very short, both above and beneath ; above dark brown, the 

 extreme tips of the hairs slightly greyish ; beneath paler, with a 

 broad longitudinal patch of white extending from the middle of the 

 breast, or slightly more forwards, as far back as the pubis ; wing- 

 membrane whitish. 



"Wings from the middle of the tibia;, or slightly lower down. 



The first upper premolar fills up the space between the canine and 

 second premolar ; lower incisors 4, not crowded, in a row between 

 the canines.
