Mitra (genus)
''Mitra'' is a large genus of medium to large predatory sea snails, marine gastropod mollusks in the family Mitridae, the miter shells or mitre snails. This genus is named after the ecclesiastical headgear, the miter, because of the shells' general shape. These sea snails create shells that are considered attractive by shell collectors; the shells are solid, high-spired and are often colorful. Description The thick shell has a fusiform shape. The spire is elevated and acute at the apex. The aperture is small, narrow and notched in front. The columella is obliquely plicate. The outer lip is thickene and is smooth internally. Species Many species that were previously in the genus ''Mitra'' have been reassigned in the past years to other genera, including '' Calcimitra'', '' Gemmulimitra'', '' Isara'', ''Nebularia'', '' Neotiara'', ''Pseudonebularia'', ''Quasimitra'', '' Roseomitra'', ''Strigatella'' and ''Vexillum''.

Lip (gastropod)
In the shell of gastropod mollusks (a snail shell), the lip is the free margin of the peristome (synonym: peritreme) or aperture (mollusc), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...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 catalogue and 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 th ...

Vexillum (gastropod)
''Vexillum'' is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Costellariidae. This genus is not monophyletic. The genus ''Vexillum'' contains about 80% of costellariid diversity. It is considered a "dumping ground" for an array of unrelated forms. Description The shell is elongated, turreted, longitudinally ribbed or plicate. The spire is acuminated. The aperture is narrow. The columella shows numerous plaits. The outer lip is internally striated. ''Vexillum'' species produce complex venoms dominated by highly diversified short cysteine-rich peptides, vexitoxins, related to conotoxins. Distribution This genus is cosmopolitan and occurs in tropical and temperate seas, but primarily in shallow waters (but also at bathyal depths) of the tropical Indo-Pacific. Species Species within the genus ''Vexillum'' include: * '' Vexillum accinctum'' (G. B. Sowerby III, 1907) * ''Vexillum acromiale'' (Hedley, 1915) * '' Vexillum acuminatum'' (Gmelin, ...
