DESCRIPTION. 
Dental formula, incisors “>, canines (>, grinders 3 = 38. 
The upper incisors are short, and are arranged in two distant pairs, each pair being 
close to the canine tooth of the same side. Each tooth has a small interior pointed 
lobe. The lower incisors are very short, and have two obtuse lobes. The canine teeth are 
a little longer than the grinders, nearly straight, subulate, and sharp pointed*. The two 
anterior grinders on each side, both above and below, are small, short, conical, and sharp 
pointed. The one adjoining to them, also simply conical, is higher than the three pos- 
terior grinders of each side, which, in the lower jaw, have a double row of acute points; 
and, in the upper jaw, a triple row ; the inner row of the latter being much lower than the 
outer ones. 
The head is short, broad, and flat: the nose blunt, with a small, flat, naked muzzle. The 
nostrils, situated. at the two anterior corners of the muzzle, are small, roundish, naked, and 
scarcely one line apart. The tip of the lower jaw is rounded, and naked. Hyes concealed 
by the fur, and situated near the ears, but not covered by them. ars about the length of the 
head, or a little longer, thin, membranous, ovate, obtuse; slightly undulated, but not notched 
posteriorly, and curving forwards at the base; slightly ventricose anteriorly, without folds. 
The ear is hairy at the base behind, and there are a very few scattered hairs on its inner 
surface. The tragus is thin, broadly subulate below, tapering to a point upwards, and ending 
in a small obtuse tip ; it is attached by one corner at the base, is about two-thirds of the 
height of the ear, and is not curved or falciform, 
The back has a shining yellowish-brown colour ; the belly a yellowish-gray. The fur, soft 
and fine, is longest on the back (three lines), and both above and below is blackish at the roots. 
With the exception of the small naked space behind the nostrils, the head is covered with fur, 
but a little shorter than that on the back; towards the mouth it assumes a blackish colour ; 
it is rather coarser on the lips, and there are a few longer hairs or whiskers, but they are not 
stiff nor very conspicuous. 
The interfemoral membrane is broad, and tapers to a point along the tail, which it envelopes. 
It is thinly clothed at the base with fur similar to that on the back in colour, but shorter. It 
is also fringed with a few scattered hairs on its posterior, free margin, which is not undulated. 
* The bifid point of one of the canine teeth in Mr. Say’s specimen seems to have been an accidental circumstance.
