Kittlidiscidae is an extinct family of Middle Triassic gastropods in the superfamily Pleurotomarioidea, named to contain the genus Kittlidiscus [1] and included in the Vetigastropoda.
Note that Bouchet & Rocroi, 2005 gives Vetigastropoda simply as a clade, which not being paraphyletic, it also is, leaving taxonomic ranking to a future date. Other gastropod classifications, including those subsequent, have determined that the Vetigastropoda is a superorder. [2] [3]
The Kittlidiscidae includes the genus Kittlidiscus. [1]
Sea snail is a common name for slow moving marine gastropod molluscs usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
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.
Scissurellidae, sometimes known by the common name little slit snails, are a taxonomic family of minute sea snails, marine gastropod molluscs or micromolluscs in the clade Vetigastropoda.
Sinezona is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Scissurellidae, the little slit shells.
Trochaclididae, common name the false top snails, is a family of sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Catantostomatidae is an extinct family of marine gastropods included in the Vetigastropoda and placed in the superfamily Pleurotomarioidea.
Rhaphischismatidae is an extinct family of fossil sea snails, marine gastropod molluscs in the superorder Vetigastropoda. They date from the Lower Carboniferous (Mississippian). The family contains a single genus, Raphischisma. In the Bouchet & Rocroi, 2005), this family is assigned to the Pleurotomariacea.
Peltospiridae is a small family of gastropods that used to belong to the clade Vetigastropoda, but is now included in the clade Neomphalina
Anatomidae is a family of minute sea snails, marine gastropod mollusks in the clade Vetigastropoda.

Phasianellidae common name the "pheasant shells" or "pheasant snails" is a family of small sea snails with calcareous opercula, marine gastropod mollusks in the clade Vetigastropoda.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005.
Pleurotomarioidea is a superfamily of small to large marine gastropods included in the order Pleurotomariida of the subclass Vetigastropoda.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
