Cerionidae
Cerionidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea. Pre-2008 taxonomy According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005), the family Cerionidae is classified in the superfamily Orthalicoidea, within the informal group Sigmurethra, itself belonging to the clade Stylommatophora within the clade Eupulmonata. The family Cerionidae has no subfamilies. 2008 taxonomy Uit de Weerd (2008) moved the Cerionidae to the newly established superfamily Urocoptoidea based on molecular phylogeny research.Uit de Weerd D.

Brasilennea
''Brasilennea'' is a fossil genus of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae. The genus is known only from the Brazilian Paleocene Itaboraí Basin, in Rio de Janeiro.Salvador, R.B.; Rowson, B.; Simone, L.R.L. 2011. Rewriting the fossil history of Cerionidae (Gastropoda: Pulmonata): new family assignment of the Brazilian Palaeocene genus Brasilennea Maury, 1935. Journal of Molluscan Studies 77: 445–447. The most characteristic feature of the genus is its two spiral furrows on the body whorl. The generic name ''Brasilennea'' originally intended to imply that it is a Brazilian genus that is very similar and related to the African genus ''Ennea''. This is no longer the case, however: while the genus was originally classified in the family Streptaxidae, ''Brasilennea'' was then later transferred to the family Cerionidae Cerionidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusk ...

Cerion (gastropod)
''Cerion'' is a genus of small to medium-sized tropical air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae, sometimes known as the peanut snails. The genus is endemic to the Caribbean region. The name ''Cerion'' is based on the Greek word ''kerion'', signifying honeycomb, and is given to these shells because the form of the shell resembles that of a beehive; hence they were at one time known as beehive shells.Baker F. C. (1903). ''Shells of land and water; a familiar introduction to the study of the mollusks''. Chicago, A.W. Mumford, page 48. The fossil range of ''Cerion'' is possibly from the Upper Cretaceous of Montana, or the early Miocene of Florida."''Cerion'': a web-based resource for ''Cerion'' research and identification" accessed 5 April 2011. ...

Taxonomy 2005 taxonomy This taxonomy, as accepted by Bouchet & Rocroi, was based on the study by Nordsieck, published in 1986, and the classification as formulated by Schileyko in 1999. However Bouchet & Rocroi diverged from this classification in uniting the families Bulimulidae and Orthalacidae. They also considered the family Placostylidae as a distinct family from Orthalicidae, and the family Coelociontidae a distinct family from Urocoptidae. However, the position of the families M ...

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.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Sigmurethra
Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This is an informal group which includes most land snails and slugs. The two strong synapomorphies of Sigmurethra are a long pedal gland placed beneath a membrane and retractile tentacles. Several families in this group contain species of snails and slugs that create love darts. Sigmurethra are known from the Cretaceous to the Recent periods. Taxonomy 2005 Taxonomy In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, Sigmurethra is an "Informal Group", a subsection of the Stylommatophora.Bouchet P. & Rocroi J.-P.

Manual Of Conchology
George Washington Tryon Jr. (20 May 1838 – 5 February 1888) was an American malacologist who worked at the Academy of Natural Sciences in Philadelphia. Biography George Washington Tryon was the son of Edward K. Tryon and Adeline Savidt. In 1853 he attended the Friends Central School in Philadelphia. In 1859, Tryon became a member of the Academy of Natural Sciences of Philadelphia. He was largely responsible for the construction of new buildings for the Academy, especially, in 1866, a section for malacology. In 1869 he became the conservator in this malacological section. In 1865, together with a group of American malacologists, he founded (and financed) the American Journal of Conchology. This ended in 1872. In 1879 he started the ''Manual of Conchology; structural and systematic; with illustrations of the species'', volume 1, series 1. When he died, nine volumes of the first series had been published. From 1887 until 1888, his assistant was Henry Augustus Pilsbry. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
