"What a number of new genera!" said Lucy. "I see the forms of the shells vary very much; and how beautiful these little transparent shells are!"
"They will find a place shortly. Here is a well-known species, H. aspersa, in most of its varieties; H. pomatia, the apple-snail, now naturalized in the county of Surrey; H. ericetorum, white with brown bands, very frequent on chalky soils; H. citrina, transparent, pale yellow, sometimes with one dark band; H. muralis, from the walls of Rome; H. bidentalis, from Teneriffe; and the little Helix hispida, which you may search for in your own garden; it is small, dark brown, and rough.
"Carocolla has the shells more flattened than Helix.
"Anostoma depressa is a rare and curious shell.
"Helicina is a West Indian genus. You saw them just now. We shall find Helix in two other families.
