Laevaricella Perlucens
''Laevaricella perlucens'' is a species of tropical, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oleacinidae. Distribution ''Laevaricella perlucens'' is endemic to Dominica. The type locality is "on Morne Diablotin, the north end on the island", Dominica. ''Laevaricella perlucens'' is very restricted in range and probably meet the IUCN-criteria of Critically Endangered species. Description ''Laevaricella perlucens'' was originally discovered and described (under the name ''Glandina perlucens'') by British-born naturalist Robert John Lechmere Guppy in 1868. Guppy's original text (the type description) reads in Latin language and in English language as follows: This species had never been collected since it was described by Guppy (1868) until 2009 and his type material was subsequently lost. The single specimen collected alive in 2009 allowed figure this species for the first time. Ecology This species is restricted to higher loca ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Zoologische Mededelingen
''Zoologische Mededelingen'' was a peer-reviewed open access scientific journal publishing papers and monographs on animal systematics. The publisher was the National Museum of Natural History Naturalis in the Netherlands. The first issue appeared in 1915, as the official journal of Naturalis' predecessor, the Rijks Museum van Natuurlijke Historie. Earlier, the museum published ''Muséum d'Histoire Naturelle des Pays-Bas'' (volumes I-XIV, 1862-1908) and ''Notes from the Leyden Museum'' (volumes I-XXXVI, 1879-1914), which mainly covered the fauna of the Netherlands and the former Dutch colonies. ''Zoologische Mededelingen'' was indexed in ''The Zoological Record'' and ''BIOSIS''. A complete backlist of published volumes is presented on the institutional repository of Naturalis. The last article was published in 2014 and the journal was merged into the ''European Journal of Taxonomy The ''European Journal of Taxonomy'' is a peer-reviewed open access scientific journal for descrip ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
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.

Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

Terrestrial Molluscs
Terrestrial molluscs or land molluscs (mollusks) are an ecological group that includes all molluscs that live on land in contrast to freshwater and marine molluscs. They probably first occurred in the Carboniferous, arising from freshwater ones. Characteristics This group includes land snails and land slugs. Loss of the shell has taken place many times in different groups that are not evolutionarily closely related, and land snails and slugs are most often treated together as a single group in specialized malacological literature.Barker G. M. (ed.) The biology of terrestrial molluscs'. CABI Publishing, 2001, 558 pp. .Barker G. M. (ed.) Natural enemies of terrestrial molluscs'. CABI Publishing, 2004, 644 pp. . All terrestrial molluscs belong to the class Gastropoda. However, colonization of the land took place several times during the evolutionary past, and as a result terrestrial molluscs are classified in several different, often not closely related, gastropod taxa.
