Cythara (gastropod)
''Cythara'' is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae. This name is considered a nomen dubium. Hedley (1922: 260) and Powell (1966: 109) summarized the arguments against using the earlier name ''Cythara'' Schumacher, 1817, with much uncertainty regarding the identity of its type species, against '' Eucythara'' Fischer, 1883. The name has also been used by European authors (e.g. Knudsen, 1952; Nordsieck, 1977) for species classified now in ''Mangelia'' Risso, 1826. Description The tropical shell is relatively large. It is columbelliform and longitudinally costellated. The spire is short. The aperture is narrow and elongated. The outer lip is denticulated within. The columellar lip is striated. The margin of the mantle is slightly dilated on the right side. The shell is fusiform, smooth and longitudinally plicated or rihbed. The aperture is linear, posteriorly subemarginate. The siphonal canal is very short and nearly straight. The columell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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. phylogenetic analysis should c ...
