CARNARIA. 79 



subgenus excepted, 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 re- 

 mainder, including the index itself, consists of but two. 



To this tribe, which is almost exclusively foreign, belong the fol- 

 lowing subgenera. 



MoLossus, Geoff". Dysopes, Illig. 



The muzzle simplej 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, even 

 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 DiNOPS of M. Savi belong to this Molossus, with six inferior 

 incisors. There is one species in Italy Dinops cestonii, Savi, 

 Giorn. de Letter., No. 21, p. 230. 



M. Geoffroy calls those in which he has counted four inferior in- 

 cisors Nyctinomus.(I) 



The Molossi, at first, were only found in America ;(2) at present, 

 however, Ave 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 Cheiromeles.(4) 



It is here, perhaps, that we should also place the Thiroptera of 

 Spix, which appear to have several characters of the Molossi, and

(2) Buffon has three of them confounded by Gmel., under the common name of 

 Vespertilio molossus,- M. longicaudatus, Buff. X, xix, 2; M.fusciventer, ib. 1; M. 



guyanensis, id. Supp. VII, Ixxv. Since then they have been increased. M. rufus,

 Geoff., Temm., ib., pi. xxii, 2. These species, however, have not been suffi- 

 ciently compared with those of Buffon, nor with the 31. ursinus, Spix, pi. xxxv, 

 f. 4, and the M.fumarius, ib., f. 5 and 6.
