 The flat-toothed Bulimus. Shell oblong egg-shaped, 

 rather thin, spire short, acuminated, whorls five in 

 number, swollen, longitudinally very closely striated 

 in a wrinkled manner, and, under the lens, crossed 

 with very minute transverse striae, aperture oblong- 

 square, rather small, contracted, furnished with a 

 single flattened tooth; light olive-green, aperture

The surface of this species, in fine condition, has a 

 delicate silken aspect, occasioned by a multitude of ex- 

 tremely fine transverse striae, which are scarcely discernible 

 without the aid of a lens. The epidermis is of a peculiar 

 plum-green colour, and the lip of an intense puiple-rose, 

 distinguished by an oblong flattened tooth.

 Hah. Brazil. 



M. Deshayes has already observed that the shell figured 

 by Chemnitz under the name of Aurls virginea (Conch. 

 Cab. vol. ix. pi. 121. f. 1042) has a dift'erent aspect from 

 that commonly known to us as the B.pxidicm, figured in 

 the accompanying plate, and among the shells collected 

 by Dr. Spix in BrazO. The A^wis virginea has more the 

 form of a Partula, but I find no shell to correspond with 

 it, and take it to be merely another state of the species 

 under consideration.

 The one-toothed Bulimus. Shell oblong-ovate, spii-e

 rather rough, aperture somewhat small. Up reflected,

I am not aware that any example of this species is 

 known in fine condition with its epidermis. It is of more 

 solid growth than the B. planidens, and of a less oblong 

 form, whilst the tooth is short and blunt, not oblong and 

 flattened. The species dift'er essentially also in colour.
