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

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

 (fig. 4). 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-mem- 

 brane 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 incisors 

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

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