Head broad and flat ; muzzle thick and obtusely conical ; glands 

 of the upper lip largely developed, forming rounded prominences 

 between the nostrils and eyes ; nostrils opening level with inter- 

 vening space ; ears large, with broadly rounded tips ; inner margin 

 of the ear-conch convex, with a rounded lobe at the base directed 

 backwards and slightly outwards, passing in front of the inner 

 margin of the tragus and resting on part of its anterior surface ; 

 outer side abruptly flatly emarginate beneath the tip, causing it to 

 project outwards, again angularly emarginate opposite the base of 

 the tragus, terminating in a rounded lobe with a wart in front 

 between it and the angle of the mouth ; tragus moderately long, 

 slightly curved inwards and obtusely pointed, maintaining almost 

 the same breadth from the base to within a short distance from the 

 tip, where it suddenly diminishes in width. 



Thumb long, armed with a large and strong claw ; terminal pha- 

 lanx about twice as long as basal. Tail of nine vertebrae, the last free. 



The wing-membranes are completely devoid of hair, except in the 

 immediate neighbourhood of the sides of the body, above and beneath ; 

 behind the fur of the back extends upon the interfemoral membrane, 

 covering about half its surface, rather densely at the root of the tail, 

 but quickly thinning out into a few short scattered hairs, which 

 also extend on the backs of the tibiae to the feet ; beneath, the mem- 

 brane is naked, except at the root of the tail, where a few scattered 

 hairs occur. 



The body is clothed with short close fur, above tricoloured, at the 

 base dark ferruginous brown, then buff, the tips light yellowish brown ; 

 beneath dark ferruginous brown at base, the remaining portion buff.
