Perrinia Concinna 002
''Perrinia'' is a genus of sea snails, marine gastropod mollusks in the family Chilodontaidae. This genus has a long time been regarded as a subgenus of ''Turcica'' H. & A. Adams, 1854. Previously it was considered a (problematic) subgenus of ''Euchelus'' Philippi, 1847. Description The imperforate shell is small (less than 20 mm) and has a trochiform shape. The whorls are flattened and cancellated with a strongly indented suture. The aperture is quadrangular. The outer lip is lirate (= with fine linear elevations) within. The columella is short, nearly straight, with several tubercles near the base. Species According to the World Register of Marine Species (WoRMS) the following species are included within the genus ''Perrinia'' : * '' Perrinia angulifera'' A. Adams, 1853 * ''Perrinia cantharidoides'' Vilvens, 2017 * ''Perrinia chinensis'' (G. B. Sowerby III, 1889) * ''Perrinia concinna'' (A.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Mattheus Marinus Schepman
Mattheus Marinus Schepman (17 August 1847 – 19 November 1919) was a Dutch people, Dutch malacologist. He was one of the foremost collectors of mollusc shells in the Netherlands, and was also high on the overall list of European collectors. Dutch collectors developed an interest in natural history specimens that were collected on worldwide expeditions since the 16th century. An interest in conchology led to numerous shell publications. In 1934 the Nederlandse Malacologische Vereniging (Netherlands Malacological Society) was founded. In commemoration of its 75th anniversary, a book honoring in detail the work of Mattheus Schepman was published. His research Schepman was both a collector and a methodical scientist, which combination "made his collection of great value to the entire malacological community." He was given the opportunity to study a collection by Max Carl Wilhelm Weber, Director of the Zoological Museum Amsterdam, Zoölogisch Museum Amsterdam (ZMA). Many of the speci ...
