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.
