a large notch on the centre of the outer edge, expanded, mem- 

 branaceous, and produced to the hinder part of the crest on 

 the edge of the lower lip. Tragus distinct, large, with an ap- 

 pendage on the outer side of its tip ; eyes small, far back. 

 Wings elongate, narrow, their index-finger of one bony joint; 

 interfemoral membrane very large, elongate, slightly truncated. 

 Heel bones very large, thumb compressed ; tail elongate, su- 

 perior, half as long as the interfemoral membrane, with the 

 last joint free on its upper edge. Hind feet rather small ; 

 ankle elongate, subcylindrical ; toes nearly equal, compressed. 



Essential Characters. Nose obliquely truncated, appen- 

 daged ; lower lip rounded, with two transverse reflexed mem- 

 branaceous ridges ; ears lateral, separate, with the lower 

 outer edge expanded and continued to the hinder edge of the 

 expansions on the lower lip. Tragus distinct. 



This genus is highly interesting from its being intermediate 

 between the Saccopteri and the genus Mormoops of Dr. Leach.

 of the lower chin membrane ; wings chestnut-brown, nearly
