Cerithiimorpha
The Cerithiimorpha was a suborder of marine gastropods within the Sorbeoconcha. This taxon is no longer valid according to the current taxonomy of Bouchet and Rocroi. The previous classification system was as follows: * subclassis = Orthogastropoda * infraclassis = Apogastropoda * superordo = Caenogastropoda * ordo = Sorbeoconcha * subordo = Cerithiimorpha Previous taxonomy During the taxon's use, not all taxonomists agreed upon its structure. The listing below gives one interpretation. For example, in another accepted classification, the Campaniloidea and Cerithioidea were separated in a suborder named Discopoda. * Campaniloidea ** Campanilidae ** Plesiotrochidae * Cerithioidea ** Batillariidae ** Brachytremidae ** † Canterburyellidae ** Cassiopidae ** Cerithiidae ** Dialidae ** Diastomidae ** Eoptychiidae ** Eustomidae ** Faxiidae ** Lavigeriidae ** Litiopidae ** † Maoraxidae ** Melanopsidae ** Modulidae ** Pachychilidae ** Pachymelaniidae ** Pareorid ...

Orthogastropoda
Orthogastropoda was a major taxonomic grouping of snails and slugs, an extremely large subclass within the huge class Gastropoda according to the older taxonomy of the Gastropoda (Ponder & Lindberg, 1997). This taxon is no longer used according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Ponder and Lindberg (1997) in the book ''The Southern Synthesis'', showed the Orthogastropoda as one of two subclasses of the Gastropoda, the other subclass being a very much smaller group called the Eogastropoda, which contained only 5 families of true limpets. This subclass, Orthogastropoda, which one perhaps could call the ''true snails'', was defined most concisely as all gastropods which were not members of Patellogastropoda, the true limpets. The Orthogastropoda appeared to form a clade which was supported by unambiguous synapomorphies. These synapomorphies (a series of characteristics that appear in its members but not in the other forms it diverged from) were the ...

Apogastropoda
Apogastropoda was previously used as a major taxonomic grouping of sea snails, marine gastropod molluscs. This infraclass mostly consisted of marine limpets and operculate snails. At least 20,000 species were considered to exist within the two clades that were included, Heterobranchia and Caenogastropoda. Description Gastropods that were placed in this taxon have bifurcate tentacle nerves and two pedal commissures. Reasons for establishing Older morphological and molecular studies appeared to show that the Caenogastropoda and Heterobranchia should be considered as sister taxa, comprising the Apogastropoda. This taxon was used in taxonomy of the Gastropoda (Ponder & Lindberg, 1997). Reasons for rejection However this taxonomic grouping is no longer used (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). It is out-dated because more recent molecular studies have proved that it contains two separate evolutionary lineages, the two clades mentioned ...

Sorbeoconcha
Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda. The taxon Sorbeoconcha was named by Winston Ponder and David R. Lindberg in 1997. Taxonomy 1997 taxonomy According to the older taxonomy by Ponder and Lindberg the suborders within the order Sorbeoconcha are: * Discopoda P.

Melanopsidae
Melanopsidae, common name melanopsids, is a family of freshwater gastropods in the clade Sorbeoconcha. Species in this family are native to southern and eastern Europe, northern Africa, parts of the Middle East, New Zealand, and freshwater streams of some large South Pacific islands. These snails first appeared in the Late Cretaceous and are closely related to Potamididae. As well as unidirectional evolutionary change from one species to the next over time, the process of hybridization plays a major role in the appearance of new Melanopsidae species.Bandel K. (2000). "Speciation among the Melanopsidae (Caenogastropoda). Special emphasis to the Melanopsidae of the Pannonian Lake at Pontian time (Late Miocene) and the Pleistocene and Recent of Jordan". ''Mitt.
