''Bolma'' is a genus of medium to large sea snails with a calcareous operculum, marine gastropod molluscs in the family Turbinidae, the turban snails. Fossil records The genus is known from the Eocene to the Recent periods (age range: from 33.9 to 0.0 million years ago). Fossils shells have been found in France, Greece, Japan, Morocco, Spain, Vanuatu, Guam, Cyprus, Greece, South Africa, Spain, Austria, Italy, Slovakia, New Zealand, Australia and Tonga. There are about 5 extinct species. Description The central teeth of the radula have no cusps. They have a narrow long basal plate, which is produced above the body of the tooth. The latter is wide, oval, and not reflected above. Its lower margin is not well-defined in my specimens which are, however, not stained. The laterals are of the usual form and bear cusps. The imperforate shell has a turbinate shape. The spire is conic with whorls rounded at the periphery. The upper whorls are spiny. The base of the shell is convex. The ...

Turbinidae
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.Bouchet, P. (2014). Turbinidae Rafinesque, 1815. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=503 on 2014-07-28 Description Turbinidae have a strong, thick calcareous operculum readily distinguishing them from the somewhat similar Trochidae or top snails, which have a corneous operculum. This strong operculum serves as a passive defensive structure against predators that try to enter by way of the aperture or that would break the shell at the outer lip. These operculum are rounded ovals that are flat with a swirl design on one side and domed on the other. They are known as Pacific cat's eye or Shiva eye shells or mermaid money, and are used for decorative purposes. Etymology The common name ''turban snail'' presumably refers to the shell's similarity in appearance to a turban. However, the scient ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive catalogue and list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as th ...
