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 ...

Cymatosyrinx Idothea
''Cymatosyrinx idothea'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 9 mm, its diameter 4 mm. (Original description) The small, thin, acute shell is rose pink and not polished. It has a blunt protoconch of one and a half smooth inflated whorls, and five well rounded subsequent whorls. The suture is distinct and appressed. The adjacent fasciole is constricted. There is no spiral sculpture. The axial sculpture consists of (on the body whorl about a dozen) protractively oblique sigmoid riblets, faint on the base and practically absent from the fasciole, with subequal interspaces. The aperture is moderately wide. The anal sulcus is wide and deep, adjacent to the suture and with no subsutural callus. The outer lip is thin, sharp and prominently produced. The inner lip is erased. The columella is stout, short, white and obliquely attenuated in front. The siphonal canal is wide, short and hardly di ...

Globidrillia Ferminiana
''Globidrillia ferminiana'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The shell grows to a length of 14 mm, its diameter 5 mm.

Spirotropis Centimata
''Spirotropis centimata'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The size of an adult shell varies between 10 mm and 34 mm. (Original description) The pure white shell has a pointed turreted spire, a brownish glossy rounded protoconch of 2½ whorls, and nine or ten subsequent whorls. The fasciole is wide, sloping, reaching to the somewhat appressed suture, smooth except for the deeply arched incremental lines. The transverse sculpture, aside from lines of growth, consists of thirteen or fourteen peripheral nodules, well elevated, and on the body whorl somewhat elongated and obliquely set. There is no spiral sculpture even on the siphonal canal. The fasciole is so wide, and the whorls increase so rapidly, that the shell has a peculiarly conical aspect. The base of the shell is moderately rounded. The aperture is moderately wide, with a very wide and deep anal notch, and the outer lip correspondingly curved forward, ar ...
