362 EMBALLONURIDiE. 



of the ear narrowly rounded oflf; upper third of the outer Diargin 

 slightly concave, then slightly convex, emargiiiate opposite the base 

 of the tragus, terminating in a rounded lobe midway between the 

 base of the tragus and the angle of the mouth : tragus narrow, 

 maintaining the same breadth to the tip, which is rounded off; 

 inner margin slightly convex, outer slightly concave. 



Wing-membrane from the tarsus. Peet small ; toes nearly equal. 

 Last two vertebrte of the tail projecting on the upper surface of the 

 interfemoral membrane. Interfemoral membrane large, convex be- 

 hind ; calcaneum very long. 



Upper incisors slender, nearly equal in vertical extent, the inner 

 one on each side slightly longer, in pairs, separated from the canines 

 by a space, and also in the middle ; lower incisors not crowded ; 

 first upper premolar minute, in the centre of the space between the 

 canine and the second premolar ; first lower premolar small, half 

 the vertical height of the second, but nearly equal to it in cross 

 section.

Emballonura atrata, Peters, MB. Akad. Berl. 1874, p. 693. 



Ears long, slightly shorter than the head, pointed, outer margin 

 emarginate above, with fourteen transverse folds ; tragus expanded 

 above, almost hatchet-shaped. 



Thumb longer than in any of the other species of the genus, being 

 one fifth the length of the forearm. 



Wings from the distal extremity of the tibia. Tail and calca- 

 neum longer than the tibia. 



The fur of the back is longer than that of the ventral surface, 

 but on both surfaces slate-grey at the base, at the extremities black. 

 As the dark-coloured extremities are longer on the upper than on 

 the ventral surface, the hair of the back appears greyish black, while 

 that of the abdomen is dark grey. 



The second upper premolar with weU-developed anterior and pos- 

 terior secondary cusps. 



This species is at once distinguished from E. monticola and E. 

 seinir,audata by its smaller size, which but slightly exceeds that of 

 E. nigrescens. It agrees with the latter in the form of the tragus, 

 and with E. monticola in the length of the ears. In the position of 

 attachment of the wing-membrane to the end of the tibia it re-
