the ear-conch regularly circular ; antitragus much longer than high, 

 convex, separated posteriorly by an angular notch ;; tragus quadrate 

 with rounded angles, no prominent lobule at the base of the outer 

 margin ; keel of the ear-conch well developed, thickened and 

 flattened externally. 



Muzzle very obliquely truncated, the extremity of the nose pro- 

 jecting much beyond the retracted upper lip, which is also concealed 

 by a fringe of short hairs ; nasal apertures directed forwards and 

 downwards ; the cartilaginoxis sharply cut edges of the nostrils 

 projecting laterally and above, terminating the muzzle in front; 

 sides of the face behind the eyes in front of the ears much flattened, 

 in front of the eyes prominent, convex, concealing the eyes when 

 viewed anteriorly ; lips smooth, without vertical wrinkles ; sides of 

 the lips very thick, the outer edge exceeding the inner in length, 

 fringed with short fine hairs. 



Gular sac large in male, rudimentary in female. 



Wings from the lower end of the tibia. 



Fur above reddish brown, paler, almost buff, at the base of the 

 hairs ; beneath much paler. 



On the upper surface the wing-membrane is covered as far as a 

 line drawn from the middle of the humerus to the knee ; and a band 

 of fur extends from the commencement of the middle third of the 

 forearm along its posterior margin to the metacarpal bone of the 

 fourth finger, covering one third of its length, and passing across it 

 to the angle between it and the metacarpal of the third finger ; be- 

 neath, the wing-membrane external to the humerus is naked. 



First upper premolar minute, in the outer angle between the 

 canine and second premolar ; lower incisors crowded, bifid. 



Length, head and body about 5", tail 2"-8, ear l"-5, tragus 

 0"-2x0"-l, forearm 2"-9, thumb 0"-45; third finger — metacarp. 

 3", 1st ph. l"-35, 2nd ph. l"-6; fourth finger— metacarp. 2"-9, 

 1st ph. 1"-15, 2nd ph. 0"-25 ; fifth finger— metacarp. l"-65, 1st

In the form of the muzzle and ears very similar to the preceding 

 species, but the ears are comparatively much smaller ; laid forwards
