66 MAMMALIA. 
III. According to the characters of M. Geoffroy, we further separate 
from the Roussettes the CeruHatotres which have the same kind of 
grinders, but whose index finger, short, and consisting of three phalanges, 
like that of the preceding, wants, however, the nail. The membranes 
of their wings, instead of meeting at the flank, are joined to each other 
on the middle of the back, to which they adhere by a vertical and longi- 
tudinal partition. Very often they have but two incisors.

of Peron). Brown or red. From Timor. 
The Roussettes being withdrawn, we have the true Bars left, which 
are all insectivorous, and have three grinders on each side in each jaw, 
bristled with conical points, that are preceded by a variable number of 
false molars. Their index finger never has a nail, and, one subgenus ex- 
cepted, the membrane is always extended between the two legs. 
They should be divided into two principal tribes. The first has three 
ossified phalanges in the middle finger of the wing, but the remainder, in- 
cluding the index itself, consists of but two. 
To this tribe, which is almost exclusively foreign, belong the following 
subgenera. 
Motossus, Geoff.—Dysorxs, IIlig. 
Has the muzzle simple; ears large and short, arising near the angle of 
the lips, and uniting with each other on the muzzle; the tragus short, 
and not enveloped by the conch(a). The tail occupies the whole length 
of their inter-femoral membrane, and, more frequently, even extends 
beyond it. They have almost always two incisors in each jaw, though, 
according to M. Temminck, several of them have at first six below, of 
which four are successively lost. 
The Dinoprs of M. Savi belong to the Molossus with six inferior in- 
cisors. ‘There is one species in [taly-—Dinops cestonii, Savi, Giorn. de 
Letter., No. 21, p. 230. 
M. Geoffroy calls those in which he has counted four inferior incisors 
Nyctinomus*. 
The Molossi, at first, were only found in America}; at present, how-

€ (a) The conch is a deep conical cavity, situated within the eminences of the 
outer part of the ear; it is bounded above by a prominent curved margin, which is 
called the antihelix; and the cench leads to the canal, through which the sound 
passes into the interior of the ear.—Ene. Ep.
