The Skeneidae are a speciose family of minute to small marine gastropod molluscs in the superfamily Trochoidea. [1]
The former subfamily Skeneinae (in the family Turbinidae) was loosely defined. Information on the specific characters of this family are incompletely described. Recent molecular evidence suggests that a number of these genera in Skeneinae probably belong to other families altogether, so many of these assignments must be regarded as provisional. Williams noted in 2012 that "this group is in a desperate need of revision". [2] [3] [4] The subfamily Skeneidae has been upgraded to the status of family Skeneidae, comprising most genera formerly in the subfamily Skeneinae. But even then, the family Skeneidae represents a polyphyletic, “skeneimorph” assemblage. [5] It should be pruned of many genera which would go to the superfamily Seguenzioidea according to Kano (2008) [6] Until a researcher formally assigns them to a seguenzioid family in the literature, the database WoRMS prefers to keep them unchanged.
This family is assemblage of small to very small shells that lack a nacreous structure. The shells are white and show no color patterns.
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.
Chilodontaidae is a taxonomic family of mostly small deepwater sea snails, marine gastropod molluscs in the clade Vetigastropoda.
Rissoidae is a large family of very small and minute sea snails with an operculum, marine gastropod mollusks in the superfamily Rissooidea and the order Littorinimorpha.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Eulimidae is a family of very small parasitic sea snails, marine gastropod mollusks in the superfamily Vanikoroidea.
Elachorbis is a genus of minute sea snails or micromolluscs, marine gastropod molluscs in the family Tornidae.

Conradiidae is a taxonomic family of very small sea snails, marine gastropod molluscs or micromolluscs. These genera were previously included in the polyphyletic family Skeneidae. They belong within the clade Vetigastropoda, and the superfamily Trochoidea.
