1 8 Lloyd's natural history. 



the same numbers hold good for the pre-molars j the molars 

 being three pairs in each jaw. The nose-leaf consists of three 

 portions, of which the anterior is horse-shoe shaped, usually 

 with a deep median incision in front, the posterior is erect and 

 pointed, while the middle one, which is situated between and 

 behind the nostrils, is flat in front, and bent up behind into an 

 erect process, usually consisting of two flat moieties, of which 

 the front one is placed transversely, and the hinder one longitu- 

 dinally. The ears are lateral and free ; and the tail (which, as 

 in all British Bats, is enclosed in the membrane connecting the 

 hind-limbs) is relatively short. 



The members of the genus have a distribution co-extensive 

 with that of the family.
