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 ...

Bivalvia
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs 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 estim ... that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into Ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they a ...

Mollusca
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.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Glycymerididae
Glycymerididae, often misspelled as Glycymeridae, common names dog cockles or bittersweets, is a worldwide family of salt water clams, marine bivalve mollusks in the order Arcida. They are related to the ark clams. This family contains 45 extant species in four genera. Description In this family the shell is generally round in outline and is slightly longer than it is wide. The external ligament lacks transverse striations. The shell in some genera is smooth and in others it is ribbed. History of the name Authority of Glycymerididae has been incorrectly attributed to Newton (1916 or 1922) by a great number of authors. While Newton was the first to publish this name, Dall (1908) had previously established the subfamily Glycymerinae , which gives him priority for the family name under Article 36 of ICZN. The name comes from the Ancient Greek word ''glykymaris'' (perhaps from ''glykýs'' "sweet" and ''méros'' "part"), a word which is only recorded once in Greek literature. T ...

Lovell Augustus Reeve
Lovell Augustus Reeve (19 April 1814 – 18 November 1865) was an English conchologist and publisher. Life Born at Ludgate Hill, London, on 19 April 1814, he was a son of Thomas Reeve, draper and mercer, by his wife Fanny Lovell. After attending school at Stockwell, he was apprenticed at the age of 13 to Mr. Graham, a local grocer. The chance of purchase of some shells led to a lifelong interest in conchology. In 1833 he attended the meeting of the British Association for the Advancement of Science at Cambridge. At the end of his apprenticeship Reeve paid a visit to Paris, where he read a paper on the classification of Mollusca before the Academy of Sciences. On his return to London, he set to work on his first book, ''Conchologia Systematica'' (2 vols. London, 1841–2). From 1842, he traded as a natural history dealer. Using profits made by the sale of Dutch Governor-General of the Moluccas Van Ryder's collection from the Moluccas, which he purchased at Rotterdam, and with t ...

George Brettingham Sowerby I
George Brettingham Sowerby I (12 August 1788 – 26 July 1854) was a British naturalist, illustrator and conchologist. Life He was the second son of James Sowerby. George was educated at home under private tutors, and afterwards assisted his father in the production of illustrated works on natural history. On the latter's death in 1822, he and his brother James De Carle Sowerby continued their father's work on fossil shells, publishing the latter parts of the ''Mineral Conchology of Great Britain''. He published about 50 papers on molluscs and started several comprehensive, illustrated books on the subject, the most important the ''Thesaurus Conchyliorum'', a work that was continued by his son, George Brettingham Sowerby II and his grandson George Brettingham Sowerby III. One of his first works was the cataloguing of the collection of the Earl of Tankerville. He also dealt in shells and natural history objects, his place of business being first in King Street, Covent Garden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
