Stylopsis Sulcata
''Stylopsis'' is a genus of sea snails. In other words, they are a genus of marine gastropod, gastropods being a class of mollusk. This creature is within a particular family of sea snail called Pyramidellidae.WoRMS (2011). ''Stylopsis'' A. Adams, 1860. Accessed through: World Register of Marine Species athis linkon 2011-10-26 Description The shell is subulate, opaque, smooth, and not polished. The whorls of the teleoconch are flattened.

Arthur Adams (zoologist)
Arthur Adams (1820 in Gosport, Hampshire – 1878) was an English physician and naturalist. Adams was assistant surgeon Royal Navy on board HMS ''Samarang'' during the survey of the islands of the Eastern Archipelago, from 1843 to 1846. He edited the ''Zoology of the voyage of H.M.S. Samarang'' (1850). Adam White collaborated with him in the descriptions of the Crustacea from the voyage. In 1857, during the Second China War whilst serving as Surgeon on HMS ''Actaeon'', he was present at the storming of Canton and awarded the China War Medal. He retired as Staff Surgeon aboard flagship HMS ''Royal Adelaide'' at Plymouth in 1870. He was a prolific malacologist who described "hundreds of new species, most of them unillustrated and insufficiently diagnosed". He partly worked together with his brother Henry Adams (1813–1877) and together they wrote The genera of recent mollusca: arranged according to their organization' (three volumes, 1858). He also wrote ''Travel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lip (gastropod)
In the shell of gastropod mollusks (a snail shell), the lip is the free margin of the peristome (synonym: peritreme) or aperture (the opening) of the gastropod shell. In dextral (right-handed) shells (most snail shells are right-handed), the right side or outer side of the aperture is known as the outer lip (''labrum''). The left side of the aperture is known as the inner lip or columellar lip (''labium'') if there is a pronounced lip there. In those species where there is no pronounced lip, the part of the body whorl that adjoins the aperture is known as the parietal wall. The outer lip is usually thin and sharp in immature shells, and in some adults (e.g. the land snails '' Helicella'' and ''Bulimulus''). However, in some other land snails and in many marine species the outer lip is ''thickened'' (also called ''callused''), or ''reflected'' (turned outwards). In some other marine species it is curled inwards (''inflected''), as in the cowries such as '' Cypraea''. It can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...

Journal Of Natural History
The ''Journal of Natural History'' is a scientific journal published by Taylor & Francis focusing on entomology and zoology. The journal was established in 1841 under the name ''Annals and Magazine of Natural History'' (''Ann. Mag. Nat. Hist.'') and obtained its current title in 1967. The journal was formed by the merger of the ''Magazine of Natural History'' (1828–1840) and the ''Annals of Natural History'' (1838–1840; previously the ''Magazine of Zoology and Botany'', 1836–1838) and '' Loudon and Charlesworth's Magazine of Natural History''. In September 1855, the ''Annals and Magazine of Natural History'' published "On the Law which has Regulated the Introduction of New Species", a paper which Alfred Russel Wallace had written while working in the state of Sarawak on the island of Borneo in February of that year.

Pyramidellidae
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs. The pyram family is distributed worldwide with more than 6,000 named species in more than 350 nominal genera and subgenera. This family of micromollusks has been little studied and the phylogenetic relationships within the family are not well worked out. There is an absence of a general consensus regarding which species belong to a specific genus or subgenus, contributing to much confusion. Schander (1999) names more than 300 supraspecific names. As there has been no serious generic revision of the genera worldwide, generic polyphyly can be expected to be rampant throughout the family. However, the family itself is deemed monophyletic. However a study in 2011 seems to indicate that this family is deeply nested within the Pulmon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...
