"Pupa is a curious genus. The shells resemble a chrysalis. A few minute species are found in Britain. P. muscorum I have found buried among damp moss. The larger species are natives of tropical regions. These shells are often found decollated.
"Clausilia papillaris is a pretty shell. ([Plate 9.])
"Clausilia rugosa is found in some parts of Britain, under old hedges, at the foot of old trees, and similar places. It is a tapering shell, with the aperture reversed, or left-handed, and bi-dentated: the colour red-brown. It is to be found in the vicinity of Dorking, in Surrey.
"Bulimus is a large genus. A common small species is the Gaudaloupe Bulimus.
"The largest land-shells are found in the genus Achatina. The greater number are African.
"Succinea contains a few species. One of them, S. amphibia, is common near fresh-water.
"Auricula has some resemblance to a Voluta. The aperture is longitudinal: the columella has one or more folds.
"The forms of the species in Cyclostoma are variable; but the aperture is circular, and the margin revolute, or rolled back. C. elegans is often to be found on hedge-banks or chalk soils. It is a pretty shell, sometimes white, often tinted with purple.
"In the family Lymænana, the species are amphibious; inhabiting fresh-water; but rising to the surface to breathe the air. They have but two tentacula.
"As several species are British, you may have the satisfaction of examining them for yourselves.
