Mollusks

_Shell._ Terrestrial, distinguished only from the Helix by its columella
being transverse callous; much depressed and diminished in thickness at
the lower part, subliglobular, imperforate; aperture entire, demioval,
margin acute, forming an angle at the lower base of the right lip;
operculum corneous. Inhabits groves in Europe. Nineteen species.

_Shell._ Cylindrical, generally thick; aperture irregular, semi-ovate,
rounded, and subangulated beneath; margins of outer lip nearly equal and
reflected outwardly, unconnected at their upper parts; the plait of the
columella interposed between them. Most frequently found in moss in
Europe and America. Forty species.

                      7. Genus _Clausilia_. Pl. X.

_Animal._ See Helix.

_Shell._ Cylindrical, generally fusiform; summit obtuse, the last whorl
smaller than the preceding; aperture irregular, rounded, oval; margin
united, and externally reflected. Inhabits dry situations both in Europe
and America. Fifteen species.

                       8. Genus _Bulimus_. Pl. X.

_Animals_ of this genus in formation are precisely as the Helix; they
are, however, oviparous, producing eggs with the shell containing the
animal perfectly matured; they are frequently as large as a pigeon’s
egg.

_Shell._ Oval, sometimes turriculated, oblong; the summit of the spire
obtuse, and the last whorl larger than all the others together; aperture
oblong, oval, edge disunited; in adults the lip much reflected;
columella smooth, with an inflection in the middle, the base entire, not
channeled. Inhabits mountainous situations in Europe and America; some
beautiful specimens have been found in the woods of Ohio. Sixty-three
species.
