It is impossible to give a detailed satisfactory description 

 of bats tVom dried skins. 



Skull broader than that of N. limbatusj but not so broad as 

 that of N. mqjorj and distinguished from both by its pro- 

 minent preorbital processes. The premaxillaj are joined, but 

 are less perfectly ossified than in the allied species. The 

 upper incisors are close together and parallel ; the upper 

 premolar is not in any way crowded, directly in the tooth- 

 row. Lower incisors not markedly bifurcate.

 paler, shading to pale buff on the middle line of belly. Ears 

 united by a broad straight band, which folds backwards, forming 

 a distinct naked cushion on the forehead, with thick dark 

 hair behind. Tragus very small. Wing-membranes palish ; 

 more or less yellow on the antebrachial membrane, the elbow, 

 and towards the body. Wing-membranes from middle of 

 tibia; interfcmoral membrane hugging leg to opposite the 

 same place.

 truding in front of canines, which are close together though 

 not touching.
