Neritopsidae

Neritopsidae is a family of small sea snails and freshwater snails in the clade Cycloneritimorpha (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
The great majority of species within this family are only known as fossils. The few species which are extant are sometimes termed "living fossils".
Taxonomy
2005 taxonomy
This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Neritopsinae Gray, 1847
† Naticopsinae Waagen, 1880 - synonym: Hologyridae Kittl, 1899
† Paffrathiinae Heidelberg, 2001
2007 taxonomy
Bandel (2007) have established two new subfamilies. But he recognizes Naticopsinae at family level as Naticopsidae with newly created subfamilies in it.
Neritopsinae Gray, 1847
† Paffrathiinae Heidelberg, 2001 - to be clarified if Bandel recognized this family. It is not mentioned in his work Bandel (2007).
† Cassianopsinae Bandel, 2007
† Colubrellopsinae Bandel, 2007
