Stomatia Acuminata
''Stomatia'', common name the keeled wide mouths, is a genus of sea snails, marine gastropod mollusks in the family Trochidae, the top snails. Description The spiral shell is oblong or depressed orbicular. The spire is prominent but short. The surface is tubercled or keeled. The whorls show a series of short folds below the suture. The aperture is either oblong or transversely oval, and longer than wide or the reverse. The interior of the shell is nacreous. There is no operculum. ''Stomatia'' is closely allied to ''Stomatella'', differing in the generally more elongated shell with a series of short folds or puckers below the sutures. Usually the body whorl has a tuberculous carina. The animal is too large to entirely enter the shell. The foot is large, fleshy, tubercular, greatly produced posteriorly. The epipodium is fringed, with a more prominent fimbriated lobe behind the left tentacle, and on the right there is a slightly projecting fold or gutter leading to the respira ...

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 ...

Australia
Australia, officially the Commonwealth of Australia, is a sovereign ''Sovereign'' is a title which can be applied to the highest leader in various categories.
