CARNARIA. 69 



suspended by their feet, and enveloping tliemselves with their wings, 

 so that no otlier part of the body is visible*. 



Nycteris, Cuv. and Geoff. 



The forehead furrowed by a longitudinal groove, which is even marked 

 upon the cranium, bordered by a fold of the skin which partially covers it ; 

 nostrils simple ; four incisors without intervals above and six below ; ears 

 large and separated ; tail involved in the inter-femoral membrane. They 

 are African species. Daubenton has described one by the name of the 

 Campagnol volant. Buff. X. pi. xx, fig. 1 and 2, the V. hispidus, Lin., 

 Schreb. LVI. M. Geoffroy has found others in Egypt f. 



Rhinopoma, Geoff. 



The pit on the forehead less strongly marked; nostrils at the end of 

 the muzzle, and a little lamina above, somewhat resembling a currier's 

 knife; ears united; tail extending far beyond the membrane. One is 

 known in Egypt, where it is principally found in the pyramids J. 



Taphozous, Geoff. 



A small round pit on the forehead, but no recurved leaf to the nostrils ; 

 head pyramidal ; only two incisors above, and very often none ; four trilo- 

 bate incisors below ; ears wide apart, and the tail free above the mem- 

 brane. The males have a transverse cavity under the throat. A little 

 prolongation of the membrane of the wings forms a sort of sac near the 

 carpus § (a). One species was discovered in the catacombs of Egypt, by 

 M. Geoffroy II . 



MoRMoops, Leach. 



Four incisors in each jaw, the superior tolerably large, the inferior tri- 

 lobate ; cranium singularly raised like a pyramid above the muzzle ; on 

 each side of the nose is a triangular leaf which extends to the ear**. 



Vespertilio, Cuv. and Geoff. 



The common Bats, or Vespertilions, have the muzzle without leaf or 

 other distinguishing marks ; ears separate ; four incisors above, of which 

 the two middle ones are apart, and six trenchant incisors slightly denticu-
