'''Liotiidae''' is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).<ref name="WoRMS">Gofas, S. (2013). Liotiidae Gray, 1850. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=196896 on 2013-09-07</ref>

==Description== The head of the animal is proboscidiform. The epipodial line has a pair of conical lobes and three pairs of cirri.

The white shell has a turbiniform or discoidal shape. It shows longitudinal ribs or is clathrate. The shell shows a fine lamellar sculpture. The circular aperture is feebly nacreous. The thick peristome is continuous and shows a callous varix. The multispiral operculum is hispid, corneous and has a soft, calcareous outer layer (intritacalx) formed of pearly beads that are disposed spirally.<ref>[https://www.biodiversitylibrary.org/item/77914 G.W.

== Taxonomy ==

=== 2005 taxonomy === The family Liotiidae belongs to the superfamily Turbinoidea, according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family consists of the three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * Liotiinae Gray, 1850 - synonym: Cyclostrematidae P. Fischer, 1885; McLean (1987) ranked it as subfamily of Turbinidae.<ref>MCLEAN, J. H. 1987. Angariinae and Liotiinae—the primitive living trochaceans. Ann. Rept. Western Soc. Malacol. 19: 16</ref> * † Brochidiinae Yochelson, 1956 * † Dichostasiinae Yochelson, 1956

=== 2008 taxonomy === Liotiidae was moved to the redefined superfamily Trochoidea according to Williams et al. (2008).<ref name="Williams 2008">Williams S. T., Karube S. & Ozawa T.
