Considerably smaller than N. straminea, but with similarly shaped 

 muzzle and ears. The inner side of the ear-conch is very convex 

 forwards, reaching more than halfway between the eye and the end 

 of the muzzle ; the tip is shortly rounded off, and the upper half of 

 the outer margin is deeply concave, the lower half convex : tragus 

 in form like an equilateral triangle with the base uppermost, its nar- 

 rowest portion being opposite the base of its inner margin, its 

 broadest above ; the upper and inner angle projects inwards so that 

 the inner margin of the tragus is concave above ; the front surface 

 is very concave. 



Thumb very short ; wings attached higher up than in N. strami- 

 neus to the inner sides of the inferior surface of the tibia; cal- 

 caneum feeble, termination not distinct. Pur as in iV. stramineus, 

 but darker. 



Outer upper incisors on each side separated by a considerable space 

 from the canine, blunt, directed almost vertically downwards ; inner 

 incisor slanting much inwards so as to approach very closely its 

 fellow of the opposite side ; lower incisors extremely small, in the 

 direction of the jaws ; first upper premolar very small, the second 

 more than double its size, but not half the size of the third premolar, 

 from which it is separated by a wide interval above, owing to the
