The skull is chiefly distinguished by its rotundity, due to the outward bulging
of the zygomatic arches; by the contraction of the muzzle at its base; by the
concavity below the orbits; by the anterior expansion of the muzzle; by its rather
round than vertically elongated posterior nares ; by the great development of the
orbital ridges; by the expanded frontal depression behind them; and, lastly, by its
relatively rather small molars and premolars.
The vertebral formula is C. 7, D. 12, L. 7, S. 3, caudal 17. The neural arch
ceases on the fifth caudal, beyond which the vertebrae rapidly increase in length to
the ninth, after which they again gradually diminish in size.

A specimen of this species, which is very common in the peninsula of India
and in Burma, wherever fruit is abundant, was obtained at Bham6. In this specimen
I find two lower incisors only, which do not rise above the level of the gum. The
lower inner incisors have probably fallen out, and their former position become
hidden by the gum closing in above, while the interval naturally existing on each
side between the canines and the incisors, causes the remaining two incisors to appear
symmetrically placed between the canines, each incisor occupying the centre of each
half space.

Ears large, acutely pointed, outer margin deeply hollowed out beneath the tip ;
antitragus large, separated from the outer margin of the ear by an acute angular
notch; nose-leaf well developed, anterior horizontal portion broad, projecting laterally,
and in front beyond the upper lip, so as to completely conceal the muzzle when viewed
from above; the anterior flattened portion of the central nose-leaf is moderately
broad below, the upper part slightly narrowed and rounded off above; terminal
portion of the hinder nose-leaf short, sides almost straight, slightly convex.
Wing-membrane attached to the ankles; tail short, and contained, with the
exception of the extreme tip, within the interfemoral membrane, the posterior free
margin of which is concave.
