Toledonia is a genus of sea snails, marine gastropod molluscs in the family Cylichnidae. [2]
Toledonia is the type genus of the subfamily Toledoniinae.
Toledonia was originally described by American malacologist William Healey Dall in 1902. [1] Dall's original text (the type description) reads as follows:
TOLEDONIA, new genus.
Shell small, smooth, thin, imperforate, succineæform; pillar continuous with the basal margin of the aperture, straight, but with an elevated thin plait near the base of the pillar, which appears to be continued into the coil of the shell; nucleus smooth, dextral; soft parts unknown. Type, T. perplexa Dall.
This little shell has a combination of characters which prevent its being assigned to any known genus. It differs from any of the Pyramidellidae in its form and dextral nucleus; from the Acteonidae by its peculiar pillar and dextral nucleus; from immature Ringicula by its single plait and general aspect. It is not certain even to what family of gastropods it should be assigned. As it was dredged at a considerable depth there seems no reason to doubt it is normally marine.
Species within the genus Toledonia include:
Cymbuliidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks in the superfamily Cymbulioidea.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Tiberia is a genus of minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies. Tiberia is the only genus in the tribe Tiberiini.
Trimusculus is a genus of medium-sized air-breathing sea snails or false limpets, marine pulmonate gastropod molluscs in the family Trimusculidae.
Hipponicidae, common name hoof shells or hoof snails, is a family of small sea snails, limpet-like marine gastropod molluscs in the superfamily Vanikoroidea.
Egila is a genus of small sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.
Turritriton is a genus of medium-sized sea snails, marine gastropod molluscs in the family Cymatiidae. This is often still regarded merely as a subgenus of the genus Cymatium.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Pendromidae is a family of gastropods in the clade Vetigastropoda.
Solariellidae is a family of small sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Cylichnidae, common name the "chalice bubble snails" or "canoe bubble snails" is a family of sea snails or bubble snails, marine gastropod mollusks in the superfamily Cylichnoidea.
Bittium is a genus of very small sea snails, marine gastropod molluscs in the family Cerithiidae, the horn snails.
Kleinella is a small genus of sea snails, pyramidellid gastropod mollusk or micromollusks. This genus is currently placed in the subfamily Turbonillinae.
Ptychatractidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Turbinelloidea.
Pyramidella is a genus of minute to medium-sized sea snails, marine gastropod mollusk in the subfamily Pyramidellinae of the family Pyramidellidae, the pyrams and their allies.
Bathysciadium is a genus of sea snails, deep-sea limpets, marine gastropod mollusks in the family Bathysciadiidae.
Velutina is a genus of small sea snails, marine gastropod mollusks in the family Velutinidae.
Ebala is a genus of sea snails, marine gastropod mollusks in the subfamily Ebalinae, family Murchisonellidae.
Crenella is a genus of bean mussels in the family Mytilidae.
