Shell description

The genus Libera was described by Andrew Garrett in 1881. Garrett's type description reads as follows:[3]

Shell small, widely umbilicated, umbilicus (in adults) strongly constricted so as to form a cavernous or pouch-like cavity; whorls 7-9, costulate or striate, last one angulata or carinate, rarely rounded; aperture subrhomboidal or securiform; peristome thin, simple, straight; parietal region with one or two, and the palate with (rarely without) two or three, internal laminae; columella emarginate and furnished with a spiral fold.

Life cycle

These snails lay their eggs into the umbilicus of their own shells.[4]
