Bourciera
''Bourciera'' is a genus of neotropical terrestrial gastropod mollusks or land snails in the family Helicinidae. All species in the genus have an operculum. In 1907, an attempt was made to rename the genus ''Pseudhelicina'', sometimes corrected to ''Pseudohelicina,'' on the basis of the fact that ''Bourciera'' was also the name of a genus of birds, but according to MolluscaBase this replacement was unnecessary and ''Bourciera'' is still used. H. Burrington Baker considered ''Bourciera'' among the most primitive of terrestrial mollusks. Distribution The genus was initially described from Ecuador based on specimens collected by Jules Bourcier, after whom it was named. It is also known to occur in Peru. Species Species within the genus ''Bourciera'' include: * ''Bourciera fraseri'' Pfeiffer 1859 * ''Bourciera helicinaeformis'' Pfeiffer 1853 * ''Bourciera striatula'' Miller 1879 * ''Bourciera viridissima'' Miller 1879Miller, Konrad (1879).

Helicinidae
Helicinidae is a family of small tropical land snails which have an operculum. They are terrestrial operculate gastropod mollusks in the superfamily Helicinoidea. These snails are not at all closely related to the air-breathing land snails, despite a superficial similarity of the shells. The name "Helicinidae" immediately reminds most people of "Helicidae", the most popular group of land snails including e.g. Helix pomatia, but the important two letters "ni" only from the Latin diminutive of the latter name alluding to superficial similarities of otherwise completely different things. Distribution These snails are found in tropical and subtropical areas but they have an odd distribution: they are restricted to the Caribbean islands and some Indo-Pacific and Pacific islands, as well as the edge of the Asian and Australian continents. Some species are found in the southern United States, from Louisiana to Florida; others in Central and South America. Taxonomy Helicinidae b ...

Louis Pfeiffer
Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botanist and conchologist. Early life, Education & Medical Career Louis Pfeiffer was born in Cassel, the eldest son of the jurist Burkhard Wilhelm Pfeiffer and his wife Louise (née Harnier). Pfeiffer received his primary education in the Cassel Lyceum, where he distinguished himself academically, and by the age of fifteen was already at the top of his class. In 1820, political tensions forced his father to relocate the family to Lübeck, but Louis continued to excel, reaching the top of his class there as well. At the age of sixteen, Pfeiffer entered into university to study medicine, first at the University of Göttingen, and finally at the University of Marburg, where he studied under such prominent scientists as Georg Wilhelm Franz Wenderoth and Ernst Daniel August Bartels, graduating in 1825.Hodvina, Sylvain.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Neotropical
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are di ...

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: * Saxicolous creatures are rock dwelling. "Saxicolous" is d ...

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. The anatomy, behavior, feeding, a ...

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.
