Of a slightly variable form, the mantle arming at its free edge a kind of ring or thick collar, especially in front, and faintly divided into two lips; foot oval, plane, smooth beneath, inflated and granular below, joined to the visceral club by a nar- row peduncle; head sufficiently distinct ; anterior tentacula very evident and inflated at top, the posterior very long; the mouth a vertical cleft provided with two labial lobes, a sort of marginal tooth, and with a small, oval, lingual club. Shell. The name Helix was given to this genus from the spiral shape of the shell, which varies much in form, but generally globular, and ventricose, conoid but never turriculated ; summit generally obtuse, aperture varying much in size, sometimes very large, sometimes-small, always regulated by the turn of the spire ; oval, semilunar, more wide than long, edges disunited, entering little into the interior; right lip or margin thickened or reflected. Inhabits the groves and woods of Europe.. One hundred and sixty-eight species. Helix vesicalis. Helix cepa. H. gigantea. H. heteroclites. H. polyzonalis. H. discolor. H. monozonalis. H. lactea.
