Type-species. — Anoura geoffroyi Gray. 
Geographic distribution. — Tropical America, north to southern 
Mexico. 
Number of forms. — Only one species is currently recognized. 
Characters. — Like Lonchoglossa , but with no external tail; zygo- 
matic arch incomplete or imperfectly ossified; outer upper incisor 
noticeably elliptical in section, the outline of its anterior surface tri- 
angular; anterior upper premolar (pm 2 ) separated from canine by 
a space about equal to length of its base. 
Species examined. — Anoura geoffroyi Gray.

Upper incisors minute, styliform, the inner smaller than the outer, 
the teeth of each pair close together, though not in contact, the inner 
teeth separated from each other and the outer separated from canines 
by spaces about equal to that occupied by the two incisors together. 
Anterior upper premolar (pm 2 ) much smaller than the others, nearly 
in contact with canine, but separated from second premolar (pm 3 ) by 
distinct space. Other teeth as in M onophyllus , except that inner bor- 
der of upper molars is narrow and convex. Skull essentially as in 
M onophyllus , but zygomata very slender, basiphenoid pits obsolete, 
and hamular processes ligulate, curved outward and backward, and 
slightly twisted. Tail very rudimentary or absent, when present ex- 
tending to edge of narrow interfemoral membrane, but the vertebrae 
incompletely ossified, so that the tail might easily be overlooked. 
Species examined — Lonchoglossa caudifera (Geoffroy).
