Prunum sapotilla, from here.

Belongs within: Volutoidea.
Contains: Marginellinae, Pruninae, Mesoginella.

The Marginellidae, margin shells, are a group of small neogastropods with a thickened lip to the shell and lacking an operculum. Members of the subfamily Marginelloninae are generally larger than Marginellinae and have a distinctive short radula bearing broad rachidian teeth with a large number of cusps. The Granulininae have cylindrical shells without an external spire. Marginellinae are characterised by the morphology of the gland of Leiblein which has a long, convoluted duct and ends in a terminal bulb. Members of the genus Prunum have a relatively large shell with a strong callus.
