The muzzle is narrower and the head apparently less elevated than 

 in either A. cinerea or A. novehoraceiisis ; the nostrils are also not 

 60 "widely separated, and, owing to the less development of the 

 glandular prominences of the upper lip, project more. The ears are 

 very differently shaped from those in either of these species; they 

 are much longer than broad, and there is a distinct tip (Plate XVI. 

 fig. 3). The inner margin commences in a large rounded lobe, the 

 posterior part of which is narrow and rounded and projects back- 

 wards ; about one third of the inner margin above the base is 

 straight, then regularly and slightly convex to the tip. The outer 

 margin is nearly straight from the tip to the terminal lobe, inter- 

 rupted only by a slight but distinct emargination immediately 

 beneath the tip ; the terminal lobe commences opposite the front 

 margin of the tragus, and projects considerably outwards, being 

 much larger than in either A. cinerea or A. noveboracensis. The 

 tragus is much broader in the upper third than in A. cinerea, more 

 obtuse at the tip and less curved inwards. 



Wings from the base of the toes ; thumbs and feet moderate. 



The fur of the body extends upon the membranes as in A. cinerea, 

 but to a less extent. Scarcely more than half the upper surface of 

 the interfemoral is covered. A narrow portion of the wing-mem- 

 brane external to the legs is covered, and the short close fur reap- 

 pears on the toes. Inferiorly a band of short fur passes outwards 

 posterior to the forearm to the carpus.
