the muzzle as far forward as a point corresponding to the position of 

 the upper incisors beneath ; outer and inner margins continuous, 

 evenly convex above, the inner margin with three minute horny 

 points ; antitragus well developed, separated by a deep notch, qua- 

 drangular with shortly rounded angles, the length of its base but 

 slightly exceeding the depth of its anterior margin ; tragus small, 

 quadrate, its superior margin directed upwards and inwards, a small 

 projection at the base of its outer margin ; keel of the ear-conch 

 large, thickened, expanded, and flattened externally in its lower 

 third. Extremity of the nose projecting very much, the distance 

 from the anterior margin of the nostril to the margin of the upper 

 lip exceeding the diameter of the base of the antitragus ; upper lip 

 with vertical wrinkles. 



Wings-membrane from the middle of the tibia. 



Fur very short above and beneath ; dark brown above, the base 

 of the hairs whitish ; beneath dirty yellowish-white, the sides of the 

 body brown. 



The first upper premolar stands in the tooth-row and fills up the 

 narrow space between the canine and second premolar ; lower incisors 

 very small, not occupying all the space in front of the canines.

Ears shorter than the head, united upon the muzzle as in the 

 preceding species, but by a deeper band ; outer and inner margins 

 of the ear-conch continuous, evenly rounded above, the inner margin 

 with three minute horny points ; antitragus half-oval, arising abruptly 

 from a point behind and on the same level with the angle of the mouth, 

 directly below the posterior commissure of the eyelids, separated pos- 

 teriorly by a narrow moderately deep notch; tragus small, quadrate, 

 superior margin straight, parallel to the base of the tragus ; keel of 

 the ear-conch small, straight, not expanded in lower third. Extre- 

 mity of the muzzle not projecting as much as in the preceding 

 species, the distance from the anterior margin of the nostril to the 

 margin of the upper lip not exceeding the length of the base of the 

 antitragus ; upper lip very expansible, with deep vertical wrinkles. 



Wing-membrane from the distal third of the tibia. 



Fur rather short, but longer than in the preceding species ; above, 

 whitish at the base, then dark brown to the tips of the hairs; be-
