ORDER CARNASSIER. 7 



there will remain the genuine bats, which are all 

 insectivorous, and all of which have cheek-teeth fur- 

 nished with conical points. The index is never 

 provided with a nail ; and, with the exception of a 

 single sub-genus, the membrane always extends 

 between the two legs. 



They must be divided into two principal tribes. 

 The first has upon the middle finger of the wing 

 three ossified phalanges, but the other fingers, and 

 the index itself has but two. 



To this tribe, which is altogether foreign, belong 

 three sub-genera. 



The Molossi, (Molossus, Geoff. Dysopes, Illiger.) 



Have a simple muzzle ; ears large and short, origi- 

 nating from the angle of the lips, and uniting one to 

 the other upon the muzzle ; the parotis short, and not 

 enveloped by the conch. We reckon but two inci- 

 sors in each jaw. Their tail takes up the whole 

 length of the interfemoral membrane, and often ex- 

 tends beyond it. All the species come from Ame- 

 rica, and are more or less brown. They were con- 

 founded by Gmelin under the common name of 

 Vespertilio Molossus, but M. GeofFroy has already 

 distinguished nine species, of which BufFon has only 

 three, viz., the Molossus longicaudatus, the Molossus 

 fusciventer, and the Molossus Gui/anensis. The de- 

 scription of the others will be found in the Ann. du 

 Mus.VI. 150. 



The Nyctinomes (Geoff.) 

 Have four incisors below ; the upper lip is high, and
