3. RHINONYCTERIS. 



Khinonicteris, Oray, P. Z. S. 1847, p. 16. 

 Rhinonycteris, Gray, P. Z. S. 1866, p. 81. 



Nose-leaf horseshoe-shaped in front, the horizontal membrar^e 

 consisting of two laminae, whereof the overlying one is deeply 

 emarginate in front, the sides of the emargination bent up, and 

 supporting (as in Tricenops) the anterior portion of a small flat 

 horizontal longitudinal process, which ends behind and between the 

 deeply sunken nasal orifices ; from the centre of the base of the 

 horseshoe behind the nostrils a pointed process projects forwards, 

 behind it is the opening of a deep central cell, which is bounded on 

 each side by a longitudinal cell, beyond which and above the eye are 

 two smaller cells ; immediately behind the central cell is the longi- 

 tudinal opening of a depression, which is evidently homologous with 

 the frontal sac of many species of the genus Phyllorhina. 



Ears separate, without a distinct antitragus ; the outer margin of 

 the ear-conch arising behind and below the eye. No process from 

 the proximal extremity of the second phalanx of the third finger ; 

 toes equal, each of two phalanges.

This genus is evidently intermediate between Tricenops and 

 Phyllorhina, though it agrees more closely with the former than 

 with the latter. 



1. Rhinonycteris aurantia.

Head long ; muzzle thick, obtuse, flattened laterally ; ears shorter 

 than the head, with acutely pointed tips ; the outer margin of the 

 conch commences at a short distance behind and below the eye, is 

 convex in lower half, and straight beneath the tip, which does not 

 project outwards, inner margin regularly convex, slightly flattened 

 near the tip. Nose-leaf broad, overhanging the muzzle, the sides of 

 the horseshoe with a slight notch, succeeded by a small rounded 

 projection in the centre of each side. From the centre of the base 

 of the horseshoe a small subacutely pointed process, about one tenth 

 of an inch long, projects forwards and upwards ; behind the central 

 cell the frontal glandular sac is bounded by walls of very thick 

 integument, covered with hairs (Plate VIII. fig. 2). 



Pront margins of the upper and lower lips fringed with small 

 warts. No pubic appendages in females, as in Bhinolophus. 



Wings from the distal extremity of the tibia or from the ankles ; 

 toes equal, each of two phalanges ; calcanea feeble, interfemoral 

 shortly triangular behind, the extreme tip of the tail projecting. 



Fur, above and beneath, bright golden yeUow.
