VESPERTILIO TEMMINCKII. 
and its notch having the natural position, while the exterior tooth is transversely placed, and the notches meet in form 
of a cross. Canine teeth long, and somewhat triangular. Grinders, six on each side, of which three are false 
grinders, and three carnivorous teeth ; the latter having the usual .structure which occurs in this Family. The first 
false grinder is conical, small, and simple ; the second very minute, concealed and forced inward ; the third has a 
triangular point, projecting slightly beyond the general series. The lower jaw has likewise three false grinders, and 
three carnivorous teeth on each side, disposed in a perfectly regular series : the first false grinder is conical, simple, 
and margined at the base ; the second Tery minute, and compressed ; the third is equal in length to the series of 
carnivorous teeth, which have nothing peculiar in their structure. 
The head is short, high in a vertical direction between the ears, and abruptly tapering to a broad rostrum ; 
the sides are naked ; the forehead oblong, having uniform dimensions from the vertex to the nose, which is broad and 
obtuse ; the nostrils arc directed downwards. The ears are as long as the head ; the auricle erect, obtuse, slightly 
inclined backward; the posterior margin terminating in a very small lobule; the tragus erect, linear, obtuse, and 
half as long as the auricle. The entire length from the nose to the tail is three inches and three lines ; of this the 
tail composes one inch and three lines. The expanded membrane measures ten inches : the interfemoral membrane is 
irregularly veined, and marked with obscure dots. The fur is very soft, long, and silky ; above grayish brown, and 
underneath whitish ; the tips of the hairs on the upper parts have a light grayish tint, and underneath the silky 
down of the fur is grayish brown.

I have named this species in honour of Major General Thomas Hardwicke, 
who has lately arrived in England with the fruits of his long and successful 
researches, consisting of a most extensive series of drawings, and of numerous 
collections of subjects in all branches of Zoology, made with great zeal, and a liberal 
devotion of his means, during a long residence in various parts of India.

Front Teeth, in the upper jaw two on each side, approximate in pairs near the canine teeth ; the interior tooth 
somewhat longer, nearly erect, compressed, entire, and slightly cuneate at the extremity ; the exterior tooth small and 
somewhat oblique. Canine teeth, long, compressed, with a heel interiorly at the base. Three false grinders and three 
carnivorous teeth on each side : the two first false grinders small, simple, disposed in regular succession ; at the third, 
which has a point projecting beyond the posterior grinders, and a dilatation laterally and interiorly at the base, the 
series of teeth takes a slight curve outward. The grinders in the lower jaw are disposed in a regular series, having a 
very slight inclination outward; the three false grinders are simple, compressed, somewhat dilated at the base, and 
nearly of equal length.
