Nepotilla Bartrumi
''Nepotilla'' is a genus of sea snails, marine gastropod mollusks in the family (biology), family Raphitomidae. Description This genus is allied to ''Eucyclotoma'' by its spirally grooved protoconch, but distinguished there from by its minute size, turreted Spire (mollusc), spire, and few Whorl (mollusc), whorls. Distribution Species of this genus occur off New Zealand and Australia (New South Wales, Queensland, South Australia, Tasmania, Victoria). Species Species within the genus ''Nepotilla'' include: * ''Nepotilla aculeata'' (May, 1916) * ''Nepotilla amoena'' (Sars G.O., 1878) * † ''Nepotilla bartrumi'' Laws, 1939 * ''Nepotilla bathentoma'' (Verco, 1909) * ''Nepotilla carinata'' Laseron, 1954 * ''Nepotilla diaphana'' May, 1920 * ''Nepotilla excavata'' (Gatliff, 1906) * ''Nepotilla fenestrata'' (Verco, 1909) * ''Nepotilla finlayi'' Powell, 1937 * ''Nepotilla lamellosa'' (Sowerby III, 1896) * ''Nepotilla marmorata'' (Verco, 1909) * ''Nepotilla microscopica'' (May, 1916) * ...

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 ...

Nepotilla Triseriata
''Nepotilla triseriata'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 4.6 mm, its diameter 2.4 mm. (Original description) The shell consists of 6 whorls, including the protoconch of 2 whorls, with an exsert apex, closely spirally lirate. When viewed from the apex, the contour of the spire whorls is not uniformly curved, but polygonal, and septangulate in the type. They have a central angulation, provided with a stout, rounded cord, and are constricted at the linear sutures. In the first and second spire-whorls, a smaller secondary lira arises above the angle and another below. In the third whorl another tertiary and still smaller lira is intercalated above, and another in each interval below. In the body whorl, below these, arising at the suture is a stout cord forming a second angulation, below which the base is markedly concavely onstricted, and has about ten lirae, diminishing in size anter ...
