80 MAMMALIA. 



whose thumb has a little concave palette peculiar to them, and by 

 which they are enabled to cling more closely. (l) 



NocTiLio, Lin. Ed. XII. 



Muzzle short, inflated, and split into a double hare-lip, covered 

 with odd looking warts and seams; ears separate; four incisors 

 above, and two below ; tail short, and free above the inter-femoral 

 membrane. 



The species best known is from America. It is of a uniform 

 fawn-colour Vespcrt. leporinus, Gm.,Schreb. LX.(2) 



Phyllostoma, Cuv. and Geoff. 



The regular number of incisors is four to each jaw, but a part .of 

 the lower ones frequently fall, being forced out by the growth of the 

 canini. They are moreover distinguished by a membrane resembling 

 a doubled leaf, that is placed crosswise on the end of the nose. The 

 tragus of the ear resembles a small leaf, more or less denticulated, 

 The tongue, which is very extensible, terminates in papillse, which 

 appear to be so arranged as to form an organ of suction the lips 

 also are furnished with tubercles, symmetrically arranged. They 

 are all from America, run along the ground with more facility than 

 the other bats, and have a habit of sucking the blood of animals.

 that of a Magpie. From South America. It is accused of 

 causing the death of men and animals by sucking their blood ; 

 the wound, however, is small, though it may occasionally prove 

 serious from the effects of the climate. (3)

 placed this subgenus, its description being incomplete.

 the back. The N. albiventer, Spix, 35, 2 and 4, is fawn-coloured above, white be-
