Pseudorbis is a genus of sea snails, marine gastropod mollusks in the family Skeneidae.
Procerithiidae is a taxonomic family of sea snails, marine gastropod molluscs in the clade Sorbeoconcha.
The taxonomy of the cone snails and their allies as proposed by John K. Tucker and Manuel J. Tenorio in 2009 was a biological classification system for a large group of predatory sea snails. This system was an attempt to make taxonomic sense of the large and diverse group which contains the family Conidae, the cone snails. The authors proposed extensive changes to the family Conidae in contrast to the way the group was treated in the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Bouchet and Rocroi included in the family Conidae several other groups of toxoglossan snails which had previously been placed in the Turridae.
Ersilia is a minor genus of minute sea snails, marine gastropod mollusks in the family Eulimidae.
Globularia is an extinct genus of sea snails, marine gastropod molluscs in the family Ampullinidae.
