The flat-toothed Bulimus. Shell oblong egg-shaped, 
rather thin, spire short, acuminated, whorls five in 
number, swoEen, 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 
bluish white, peritreme deep purple-rose.

The surface of this species, in fine condition, has a 
delicate sflken 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 purple-rose, 
distinguished by an oblong flattened tooth.

M. Deshayes has already observed that the sheE figured 
by Chemnitz under the name of Auris virginea (Conch. 
Cab. vol. ix. pi. 121. f. 1042) has a different aspect from 
that conunonly known to us as the B. pudicus, figured in 
the accompanying plate, and among the sheEs coEected 
by Dr. Spix in BrazU. The Anris virginea has more the 
form of a Partula, but I find no sheE to correspond with 
it, and take it to be merely another state of the species 
under consideration.

The one-toothed Bulimus. SheE oblong-ovate, spire

I am not aware that any example of this species is 
known in fine condition with its epidermis. It is of more 
soEd growth than the B. planidens, and of a less oblong 
form, whEst the tooth is short and blunt, not oblong and 
fiattened. The species differ essentially also in colour.
