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.

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

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 lamine, 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. Lars separate with- 
out antitragus.
