suspended by their feet, and enveloping themselves with their wings, 
so that no other part of the body is visible*. 
Nycreris, 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. pl. xx, fig. 1 and 2, the V. hispidus, Lin., 
Schreb. LVI. M. Geoffroy has found others in Egypt}. 
Rutnoroma, 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 ft. 
Taprnozous, Geoff. 
A smail round pit on the forehead, but no recurved leaf to the nostrils ; 
head pyramidal; only two incisors aboye, 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 ||. 
Mormoors, 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 Vespertilious, 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-
