Lora (gastropod)
''Oenopota'' is a genus of sea snails, marine gastropod mollusks in the family Mangeliidae. This genus doesn't form a monophyletic group. Therefore many species are only tentatively placed within this genus. Description In 1941 Paul Bartsch described species in this genus as having large, heavy and elongate -ovate to elongate- turreted shells. The protoconch is smooth at the apex, succeeded by a whorl with three spiral cords and rather distantly spaced axial ribs. The longitudinal ribs become stronger on succeeding whorls but evanesce at the base of the shell. The spiral sculpture weakens on succeeding whorls and finally becomes mere threads. The pear-shaped aperture is deeply channeled anteriorly. It shows in the outer lip near the summit a feeble posterior sinus. Later, in 1980, it has been stated by Bouchet & Warèn that there is a high variation within the arctic forms of this genus, such as the outer lip showing all transitions from sinuated to nonsinuated Dis ...

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 ...

Oenopota Casentina
''Oenopota casentina'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell varies between 8 mm and 13 mm, its diameter 5 mm. (Original description) The small, white shell contains about five whorls, the protoconch decorticated. The whorls show a subangular shoulder in front of the anal fasciole. The axial sculpture consists of (on the penultimate whorl about 20) low, threadlike ribs extending from the shoulder to the succeeding suture, but more or less obsolete on the body whorl. The spiral sculpture consists of faint feeble striae on the fasciole. In front of the shoulder are numerous close-set flattish small threads, extending uniformly to the siphonal canal. The anal sulcus is shallow. The outer lip is slightly arcuate, the inner lip is erased. The columella is short, and straight. The siphonal canal is hardly differentiated.

Oenopota Blaneyi
''Oenopota blaneyi'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell varies between 5.5 mm and 7 mm, its diameter 3–3.5 mm.

On some portions of the whorls these ribs blend entirely with the sinuous lines of growth. The smaller specimen of four whorls is destitute of spiral lines, either raised or incised, but the larger one of five whorls has about fifteen very faint incised spiral lines on the body whorl commencing well below the shoulder and are so shallow as to scarcely interrupt the otherwise smooth surface.
