Mathildidae is a family of small sea snails, marine gastropod molluscs in the superfamily Mathildoidea of the informal group of the Lower Heterobranchia.
(Original description) These shells recall Bittium and Turritella. They feature a blunt apex upon which a small, heterostrophic, Adeorbis-shaped protoconch is set on its edge, often tilting to one side of the axis. The operculum is reported to be multispiral and externally concave, while the soft parts of the animal are externally quite similar to those of Turritella.The dentition of the group, however, remains unknown..
This group is abundantly represented in the Eocene Tertiary of the Paris Basin. A few recent species are widely distributed, including two or three that inhabit the Mediterranean.
Genera within the family Mathildidae include:
