84 MAMMALIA, 



M. Geofftoy also separates from Vespertilio the 



Plecotus, Geoff. 



Ears larger than the head, and united on the cranium as In 

 Megaderma, &c.; the tragus large and lanceolate an operculum 

 on their auditory passage. 



The common species Vesp. aurilus, L. ; Buff. VIII, xvii, 1. 



(The Long-eared Bat.) Still more abundant in France than the 



Bat. Its ears are nearly as large as the rest of the body. It 



lives in kitchens, houses, Sec. There is also another discovered 



by Daubenton Vesj). harbastellus, Gm., Buff. VIII, 19, 2. 



Brown, with much smaller ears.(l) 



Finally, the Nycticeus, Rafinesque, has only two incisors in the 



upper jaw, along with the moderate ears and simple muzzle of the 



Vespertilio. The species known are from North America. (2) 



GaleopithecuSj Pall. 



The Galeopithcci differ generically from the Vespertilios, in the 

 fingers, all armed with trenchant nails, which are not longer than 

 the toes, so that the membrane which occupies their intervals, and 

 extends to the sides of the tail, can only act as a parachute. The 

 canini are denticulated and short like the molars. There are two 

 upper denticulated incisors widely separated from each otherj below 

 there are six, split into narrow strips, like a comb, a structure alto- 

 gether peculiar to this genus. The animals belonging to it are 

 found in the Indian Archipelago, on the trees, among which they 

 pursue insects, and perhaps birds. If we can judge by the injury 

 the teeth sustain from age, they use fruit also. Their caecum is 

 very large. 



One species only is well ascertained, the Flying Lemur.

N.B. As our plan permits us to class those animals only whose characters we 

 have ascertained either from personal observation or from very complete descrip- 

 tions and figures, we have been compelled to omit several of the genera of MM. 

 Leach, Rafinesque, &c.; and while on this subject, we must observe that there is 

 no family which stands more in need of revision than that of the Bats a revision 

 from nature and not by compilation.
