cent ; keel very deep, projecting outwards beyond the antitragus, 

 but also very slender, curved backwards and upwards ; tragus small, 

 quadrate, superior margin straight or very slightly concave, upper 

 half of outer margin concave, lower half forming a prominent angular 

 projection; antitragus considerably longer than high, terminating in 

 front between the eye and the angle of the mouth (fig. 6), separated 

 posteriorly by a deep notch. Face deeply grooved horizontally be- 

 neath the eye, which is remarkably prominent and directed forwards. 

 Muzzle slender, concave between the ears and the projecting, sharply 

 cut superior margin of the nostrils ; nasal apertures directed almost 

 laterally, separated by a wide space, which is divided in the middle

by a raised vertical ridge. Upper lip deeply furrowed by oblique

 sity ; terminal phalanx of third finger very short. Wings from the 

 distal third of the tibiae. 



Fur short, reddish brown above and beneath ; on the upper sur- 

 face extending upon the wing-membrane as far outwards as a line 

 drawn from the middle of the humerus to the knee-joint, on the base 

 of the interfemoral, and outwards behind the forearm in a narrow 

 band to the carpus. 



Teeth slender, with very acute cusps. Lower incisors 4, crowded, 

 bifid. First upper premolar small, but acutely pointed, in the centre

 in general structure, and forms with it a separate section of the 

 genus, distinguished by the peculiar shape of the muzzle.
