process rises between and behind the nasal orifices, is flattened 

 anteriorly, and posteriorly sends backwards a vertical laterally 

 compressed process, which is either connected with the front sur- 

 face of the posterior nose-leaf or free. Base of the outer side of 

 the ear expanded, forming a large antitragus. 



Dentition 1. | C.-g, ? ^ M. gj = 32. 

 Habits. Insectivorous.

 and with a small but distinct notch in front. Sides of the terminal 

 process of the posterior leaf concave. Lower lip with three grooves. 

 Wings from the metatarsus. Interfemoral membrane square

Toes equal, of two phalanges each. Iliopectineal spine united 

 by a bony isthmus to a process derived from the antero-inferior 

 surface of the ilium. 



Note. Owing to the compulsory rejection of the generic title 

 Phyllorrhina it has become necessary to substitute for it the 

 above term. 



Genus II. RHINONYCTERIS, Gray (1847). 



Nose-leaf horseshoe-shaped in front, the horizontal membrane 

 consisting of two laminae, the upper one deeply emarginate in 

 front, the sides of the emargination bent upwards, supporting 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 which is the opening 

 of a deep central cell, bounded on each side by a longitudinal cell, 

 beyond which and above the eye are two smaller cells ; behind 

 the central cell is a longitudinal depression. Ears separate with- 

 out antitragus.
