Ears united by the bases of their inner margins on the muzzle at 

 a short distance from the extremity of the nose, their round sxiperior 

 and internal margins projecting slightly beyond the end of the 

 muzzle ; general form of the ear-conch and tragus as in preceding 

 species, but the tragus is proportionately larger, and the antitragus 

 is obliquely triangular and separated posteriorly by a deep notch. 

 Upper lips very thick, with well-marked vertical wrinkles. Males 

 with a small glandular gular sac, opening in the centre of the 

 inferior surface of the neck, slightly in front of the anterior ex- 

 tremity of the sternum, by a circular orifice concealed by the fur. 



Wings from the distal third of the tibia. 



Fur, above, reddish brown with an orange tinge, the extreme 

 tips of the hairs greyish ; beneath, similar, but paler. The wing- 

 membrane on the upper surface is covered as far as a line drawn 

 from the middle of the humerus to the knee, and the base of the 

 interfemoral membrane ; the antebrachial membrane is clothed with 

 short fur ; the forearm, legs, and remainder of the wings naked. 

 Beneath, the fur extends outwards to a less distance, ending by an 

 abrupt well-defined straight margin ; the antebrachial membrane is 

 naked. The lower margin of the upper lip is fringed with fine 

 hairs, the face is almost naked ; a few short hairs form an arch on 

 the inner side of the ear-conch, and the cutaneous band connecting 

 the inner sides of the ears with the muzzle is clothed with erect 

 hairs. 



First upper premolar minute, acutely pointed, in the centre of the 

 space between the canine and second large premolar ; lower central 

 pair of incisors in front of next two, which touch the small incisors 

 on each side next the canines, but do not overlap them. 



Length (of an adult cT), bead and body 3"-4, tail 2", tail free 

 from membrane 1"-1, head l"-3, ear l"-2, tragus 0"-25x0"-20, 

 forearm 2"-4, thumb 0"-35 ; third finger — metacarp. 2"-4, 1st ph.

 0"-3 ; tibia 0"-75, foot 0"-4.
