Helix (gastropod)
''Helix'' is a genus of large, air-breathing land snails native to the western Palaearctic and characterized by a globular shell. It is the type genus of the family Helicidae, and one of the animal genera described by Carl Linnaeus at the dawn of the zoological nomenclature. Members of the genus first appeared in the fossil record during the Miocene. Well-known species include '' Helix pomatia'' (Roman snail, Burgundy snail, or edible snail) and '' Helix lucorum'' (Turkish snail). ''Cornu aspersum'' (garden snail), though externally similar and long classified as a member of ''Helix'' (as "''Helix aspersa''"), is not closely related to ''Helix'' and belongs to a different tribe of Helicinae. Taxonomy In Linnaeus' 10th edition of Systema Naturae, which marks the beginning of the zoological nomenclature, the generic name ''Helix'' had been used for a variety of terrestrial (e.g. '' Zonites algirus''), freshwater (e.g. ''Lymnaea stagnalis''), and marine (e.g. '' Fossarus amb ...

Helix Pomatia
''Helix pomatia'', known as the Roman snail, Burgundy snail, or escargot, is a species of large, air-breathing stylommatophoran land Snails, snail native to Europe. It is characterized by a globular brown shell. It is an edible species which commonly occurs Synanthrope, synanthropically throughout its range. Distribution The present Species distribution, distribution of ''Helix pomatia'' is considerably affected by the dispersion by human and synanthropic occurrences. The northern limits of their natural distribution run presumably through central Germany and southern Poland with the eastern range limits running through western-most Ukraine and Moldova/Romania to Bulgaria. In the south, the species reaches northern Bulgaria, central Serbia, Bosnia and Herzegovina, Bosnia and Hezegovina and Croatia. It occurs in northern Italy southwards to the Po (river), Po and the Ligurian Apennines. Westerly the native range extends to eastern France. Currently, ''H. pomatia'' is distribut ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial molluscs, terrestrial gastropod mollusks that have gastropod shell, shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a Polyphyly, polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum (gastropod), operculum. The largest clade of non-pulmonate land snails is the Cyclophoroidea, with more than 7,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=1549519 on 2022-12-09 For a species of ''Helix'', ''H. ceratina'' is a small snail of shell diameter max. 24 mm (28 in fossil individuals). The shell is olive-brown, with darker bands, and thin-walled. This species is endemic to Corsica. The only known extant population lives at Campo dell’Oro near the Ajaccio airport. The inhabited area was estimated at 0.34 km². However, the species was distributed more widely in prehistoric times, as fossil shells were found at three other localities on the shore (Bastia: Toga, Piana: Plage d'Arone, Bonifacio).

Species Inquirenda
In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term ''taxon inquirendum'' is broader in meaning and refers to an incompletely defined taxon of which the taxonomic validity is uncertain or disputed by different experts or is impossible to identify the taxon. Further characterization is required. Certain species names may be designated unplaced names, which ''Plants of the World Online'' defines as "names that cannot be accepted, nor can they be put into synonymy". Unplaced names may be names which were not validly published, later homonyms which are therefore illegitimate, or species which cannot be accepted because the genus name is not accepted. Species names may remain unplaced if there is no accepted species in a genus in which it can be placed, or if the type material for the species ...

Basionym
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an ''i''. Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the ''correct'' spelling of the original name (according to the applicable nomenclature rules), while a protonym is the ''original'' spelling of the original name. These are typically the same, but in rare cases may differ. When creating new taxonomic names, there are specific rules about how basionyms can be used. A new combination or name at new rank must be based directly on the original basionym rather than on any intermediate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zonitidae
Zonitidae, common name the true glass snails, are a family of mostly rather small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Zonitoidea. Zonitidae is the only family in the superfamily Zonitoidea. The family's type genus is '' Zonites'', established by Pierre Denys de Montfort in 1810. This family has no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Distribution The distribution of the Zonitidae encompasses the western Palearctic. Shell description The spiral, heliciform shells of these snails are flattened in shape with a very low spire. The shell is perforate or umbilicate. The lip of the aperture is simple, lacking thickened margin. These shells are more or less transparent as if made of glass, hence the popular name "glass snails". The shells are colorless or of an amber to brownish color. Biology Some snails in genera within this family create and use love darts as part of their mati ...

Stylommatophora is an orderPhilippe Bouchet, Jean-Pierre Rocroi, Bernhard Hausdorf, Andrzej Kaim, Yasunori Kano, Alexander Nützel, Pavel Parkhaev, Michael Schrödl and Ellen E. Strong. 2017. Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families'. Malacologia, 61(1-2): 1-526. of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes most land snails and slugs. Stylommatophorans lack an operculum, but some close their shell apertures with temporary "operculum" ( epiphragm) made of calcified mucus. They have two pairs of retractile tentacles, the upper pair of which bears eyes on the tentacle tips. All stylommatophorans are hermaphrodites. The two strong synapomorphies of Stylommatophora are a long pedal gland placed beneath a membrane and two pairs of retractile tentacles. Stylommatophora are known from the Cretaceous period up to the present day. A molecular clock estimate puts the origin of the ...
