Wikipedia / Vitrina

Vitrina is genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Vitrinidae, the glass snails.

Description

The shell is globular. There is no apertural membrane. The mantle lobe is very small. There is no penial appendix, no vagina, which means that penis, oviduct and spermatheca duct join at a common point.

These are closely allied species, in which the internal organization is in many cases more distinctive than the external aspect of the shell.

Distribution

These species occur in North America, Greenland, Europe and northern Asia.
