Paradrillia Cocoa
''Paradrillia'' is a genus of sea snails, marine gastropod mollusks in the family (biology), family Horaiclavidae. ''Coronacomitas'' was originally proposed by T. Shuto in 1983 as a subgenus of ''Paradrillia'' for ''Paradrillia gemmata''. It showed some resemblance to ''Pleurotoma multiseriata'' Smith, 1877, synonym of ''Epidirona multiseriata'' (E. A. Smith, 1877). It differs however by the position of the anal sinus which is situated on the shoulder slope and not on the shoulder itself. Species Species within the genus ''Paradrillia'' include: * ''Paradrillia agalma'' (Smith E. A., 1906) * ''Paradrillia alluaudi'' (Dautzenberg, 1932) * † ''Paradrillia astuta'' (Yokoyama, 1928) * † ''Paradrillia astutoida'' (Shuto, 1961) * † ''Paradrillia boehmi'' (K. Martin, 1914) * ''Paradrillia celebensis'' (Schepman, 1913) * † ''Paradrillia cocoa'' C.-H. Hu & X.-F. Lee, 1991 * ''Paradrillia consimilis'' (Smith E. A., 1879) * ''Paradrillia dainichiensis'' (Yokoyama, 1923) * ''Para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...
