Ears shorter than the head, rounded at the tip; inner border nearly straight, rising 
from the side of the forehead some distance above the eyes; external border broadly 
convex from the tip, with a shallow notch opposite the tragus, attached on a level with 
the angle of the mouth, but some way behind it, and behind a line drawn vertically to 
the posterior border of the eye. Tragus more than twice as high as broad, of nearly 
uniform breadth throughout, anteriorly concave, posteriorly convex, with a minute 
eminence on its external border immediately above a corresponding notch near its 
base, with the tip sharply rounded off from behind forwards. Crown of head abruptly 
raised above the flattened forehead. Muzzle broadly triangular viewed from above, 
with the tubular valvular nostrils opening forwards and outwards, and separated from 
each other by a well-defined mesial furrow. The muzzle projects somewhat beyond 
the lower lip, and on its under surface there is a median fleshy eminence; front of the 
lower lip fleshy, with a distinct median groove generally more or less defined, but 
usually not traversing the front of the lip. 
The wing-membrane arises from above the ankles. Calcaneum nearly as long as 
the lower leg. 
The fur extends on to the wing-membrane as far as a line drawn from the middle of 
the humerus to the distal third of the femur, and on to the interfemoral membrane 
as far as the exit of the tail. 
A well-defined fringe of short forwardly and downwardly directed hairs along the 
upper lip. 
General colour of fur dusky brown, hardly, if at all, paler on the under surface. 
Membranes and ears of much the same tint, but the msrgin of the wing-membrane 
edged with whitish. 
The upper incisor on each side is removed somewhat from the canine. It is a short 
cylindrical tooth with a sharp point. The canine has a sharply pointed, downwardly 
directed process on the inner side of the cingulum. The first upper premolar is small, 
and lies in the tooth-line ; it is about the height of the cingulum of the second 
premolar, which gives off anteriorly a sharp point like the one on the canine. The
