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". [1]


2005 taxonomy[edit]

This family consists of three following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

2007 taxonomy[edit]

Bandel (2007)[1] have established two new subfamilies. But he recognizes Naticopsinae at family level as Naticopsidae with newly created subfamilies in it.[1]
