CARNARIA. 79 
subgenus excepted, the membrane is always extended between the 
two legs. yy 
They should be divided into two principal tribes. The first has 
three ossified phalanges in the middle finger of the wing, but the re- 
mainder, including the index itself, consists of but two. 
To this tribe, which is almost exclusively foreign, belong the fol- 
lowing subgenera. 
Motossus, Geoff.—Dysopres, Illig. 
The muzzle simple; ears broad 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. The tail occupies the whole 
length of their inter-femoral membrane, and, most generally, eyen 
extends beyond it. They have very seldom more than two incisors 
in each jaw, though, according to Temminck, several of them have 
at first six below, of which four are successively lost. 
The Drvors of M. Savi belong to this Molossus, with six inferior 
incisors. There is one species in Italy—Dinops castor, Savi, 
Giorn. de Metter., No. 21, py 2308 
M. Geoffroy calls those in which he has counted four inferior in- 
cisors Nyctinomus.(1)— a5 
The Molossi, at first, were only found in America; 3(2) at present: 
however, we know several of both continents.(3), Some of them have 
the hinder thumb placed at a greater distance from the first finger 
than the fingers are from each other, and endowed with a separate 
motion, a character on which, in a species where it is very strongly 
marked, M. Horsfield has established his.genus CurrroMELes. (4) 
It is here, perhaps, that we should also place the Tuirorrera of 
Spix, which appear. to have several characters of the Molossi, and |,
