essential points of the form of the tragus and the for- 

 mula of the dentitioHj is very obvious on the most super- 

 ficial observation. It is, however, readily distinguished 

 from the former species by the larger size of the ears, 

 the different proportions of the wings, — which, although 

 equally broad, have not nearly the same relative length, 

 — by the darker colour of the membrane, and the lighter 

 colour of the belly. From V. Nattereri it differs in the 

 entire and simple margin of the interfemoral membrane, 

 in its larger size, and the greater length of its ears. 



The face is rather hairy, with a few stiffer hairs inter- 

 mixed ; the muzzle long and conical ; the gape wide, ex- 

 tending to the base of the ears ; the nose rather narrow, 

 and slightly depressed in the middle. Ears obviously 

 longer than the head, rounded, and bending outwards at 

 the apex, oval, thin, and transparent ; tragus somewhat 

 falciform, bending a little outwards towards the extre- 

 mity. Fur reddish grey above, brown at the base, light 

 grey beneath, blackish at the base. Dimensions : —
