Allodiscus Dimorphus
''Allodiscus'' is a genus of land snails belonging to the family Charopidae. The genus was described by Henry Augustus Pilsbry in 1892. Taxonomy Pilsbry in 1892 originally described ''Allodiscus'' as a subgenus of Helix, naming ''H. dimorpha'' ('' Allodiscus dimorphus'') as the type species. A revision of the genus in 2008 saw the addition of 31 new species.

Henry Augustus Pilsbry
Henry Augustus Pilsbry (7 December 1862 – 26 October 1957) was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial molluscs, terrestrial mollusks, and others. Biography Pilsbry (frequently misspelled ''Pilsbury'') spent his childhood and youth in Iowa. He was called "Harry" Pilsbry then, and developed an early fascination with the limited variety of mollusks he was able to find. He attended the University of Iowa, and received the Bachelor of Science degree there in 1882, but did not immediately find employment in his field of interest. Instead, Henry Pilsbry worked for publishing firms and newspapers for the next several years, but devoted most of his spare time to the ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Snails
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 gastropod mollusks that have 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 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. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Helix (gastropod)
''Helix'' is a genus of large, air-breathing land snails native to Europe and the Mediterranean region. They are the type genus of the family Helicidae, and are among the first animal genera described by Carl Linnaeus.Rosenberg, G.; Bouchet, P. (2014). ''Helix'' Linnaeus, 1758. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=153970 on 2015-02-24 Members of the genus first appeared during the Oligocene. Like most land snails, ''Helix'' species are hermaphroditic, and like other helicids, a courting pair will impale each other with hormone-rich love darts prior to exchanging sperm. Well-known species include ''Helix pomatia'' (Roman snail, Burgundy snail, or edible snail) and '' Helix lucorum'' (Turkish snail). ''Cornu aspersum'' (garden snail) – another well-known helicid – was originally described as a member of ''Helix'' (as "''Helix aspersa''"), but the prevailing classification places it as the sole member of the ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

New Zealand Subantarctic Islands
The New Zealand Subantarctic Islands comprise the five southernmost groups of the New Zealand outlying islands. They are collectively designated as a UNESCO World Heritage Site. Most of the islands lie near the southeast edge of the largely submerged continent centred on New Zealand called Zealandia, which was riven from Australia 60–85 million years ago, and from Antarctica 85–130 million years ago. They share some features with Australia's Macquarie Island to the west. History Until 1995, scientific research staff were stationed permanently at a meteorological station on Campbell Island. Since then, the islands have been uninhabited, though they are periodically visited by researchers and tourists. Protection of reserves was strengthened in 2014, becoming the largest natural sanctuary in the nation.

Gastropod Genera
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
