In this genus, which is closely allied to the last, the premaxillaries are very narrow, 
and in the adult there are only two upper incisors, which are placed close to the 
canines. The outer margin of the ear-conch is strongly angular, the tragus is curved 
inwards, and either the whole, or at least the greater part, of the upper surface of the 
interfemoral membrane is thickly clad with fur. | 
Several species are distributed over the greater part of the Nearctic and Neotropical 
Regions, two of which are almost certainly members of our fauna, though one only has 
hitherto been found within our limits. These two species may be characterized as 
follows :— 
1. A. noveboracensis. Premolars 2-2. Forearm naked, 1/50. Fur yellowish-red ; 
a white mark on each shoulder. 
2. A. cinerea. Premolars 2-3. Forearm with a hairy patch near the elbow, 2-10. 
Fur brown, tipped with white. 
Of the other established species, A. intermedia (Allen), with olive-brown fur and 
only two upper premolars, is a native of Texas and Northern Mexico, but does not 
appear to have been traced further south than Matamoras, whence there is a specimen 
in the Berlin Museum.
