 Genus — Trdenops, Dobson {gen. nov.). 



Nose-leaf horse-shoe shaped in front, tridentate behind ; horse- 

 shoe shaped portion consisting of two laminae, of which the over- 

 lying one is deeply einarginate in front, with the sides of the 

 emargination turned upwards and supporting the base of a longi- 

 tudinal, horizontal crest ending above and between the nasal ori- 

 fices ; hinder, erect portion of the nose-leaf with one cell in the 

 centre of its base, the entrance to which is guarded by a lanceolate 

 process of membrane, with cells on the sides of its front surface, 

 and one on each side behind, immediately above the eye. 



Dentition:-!. \ ; eg; pm. g;m-g- 



First upper premolar minute, placed outside the line of teeth. 



The above characters of the new genus are derived from an ex- 

 amination of six spirit specimens of a new species of bat from 

 Persia, which I now proceed to name and describe in detail. 



Tri^nops persicus, Dobson, PI. XXVIII. 



Head long ; muzzle broad, obtuse, flattened laterally, lower lip 

 with four small warts on its anterior margin ; ears nearly as broad 

 as long, funnel-shaped, with acutely pointed tips ; the outer mar- 

 gin commences in a narrow fold of skin arising from the posterior 

 corner of the eyelids, which passing backwards and slightly down- 

 wards for about 0.1 in. rises abruptly to a height of 0.2 in. forming 

 the outer side of the ear ; the inner margin is convex forwards, 

 and rises to about the same height ; at a short distance behind, it 

 is interrupted by a sudden emargination which is succeeded by a 

 triangular elevation of the rim of the ear forming the tip which 

 projects outwards owing to the concavity of the outer side of this
