Megalena
Megalena crassa, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Enidae.
Megalena is a monotypic genus, i.e. it contains only one species, Megalena crassa and therefore this species is also the type species.
The generic name is composed from the prefix mega-, which means "large" from the ancient Greek language, and from the suffix -ena, for which the etymological origin is unknown.
Specimens of this species are stored in collections in Europe: Germany, Poland and in the Netherlands.
