sublanceolate, internal margin with a distinct submedian shoulder, 

 external margin with a prominent submedian dentiform shoulder ; nos- 

 trils surmounted by a sinuate ridge bearing a series of small pads, 

 nostrils flanked by a subacute protuberance. 



Head. — Moderately elongate; rostrum considerably depressed. Ears 

 elongate, sublanceolate, the lower margin extending considerably 

 forward but failing to reach the angle of the mouth; internal margin 

 of the ear attached to the head anterior to the small eye, internal ridge 

 distinct, arcuate, passing by a moderately rounded shoulder into the 

 internal margin of the ear, distal two-thirds of the internal margin of 

 the ear straight, bearing several distinct spiniform points superior to 

 the shoulder of the internal ridge ; external margin and lower margin 

 ample, bearing a distinct acute notch at a point about opposite to the 

 shoulder of the internal ridge, distal portion of the external margin 

 straight, except the extreme apical portion which is gently concave; 

 apex subfalcate, rounded. Tragus subelliptical ; external margin with 

 a slight nodular shoulder; internal margin bearing a subapical whorl- 

 like accessory flap, which lies in a plane at right angles to the body of 

 the tragus; apex rather narrowly rounded. Nostrils ovate, bordered 

 by a low ridge, superior margin slightly depressed centrally and 

 bearing six distinct sucker-like tubercles,' lateral margins flanked by 

 an erect subdentiform flap. Labial chin-lappet transverse, forming 

 broadly rounded lobes laterally, the median portion of the inferior mar- 

 gin broadly and evenly concave, median portion of the lappet strongly 

 papillose and margined superiorly by a small rounded nonpapillose

 verse nerves very regularly disposed in the endopatagium and meso- 

 patagium; propatagium large, the anterior border totally free; uropa- 

 tagium very large, extending beyond the enclosed portion of tail a 

 distance about equal to the same. Fur of moderate length, soft and 

 silky; throat and chin with the fur floccose; endopatagium partially 

 and slightly furred above ; upper hp and muzzle with the hair bristle- 

 like in character.
