Chrysallidinae
Chrysallidinae is a taxonomic group of very small sea snails, marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies. Taxonomy Chrysallidinae has been one of eleven recognized subfamilies of the gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg 1997). (The other 10 subfamilies are Odostomiinae, Turbonillinae, Cingulininae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae.) According to Schander, Van Aartsen & Corgan (1999) there are 47 genera in this subfamily, four additional genera may also be a part of this taxon. In the taxonomy of Bouchet & Rocroi (2005), this subfamily has been downgraded to the rank of tribe Chrysallidini in the subfamily Odostomiinae. Genera Genera in the subfamily Chrysallidinae include: * '' Chrysallida'' Carpenter, 1856 - type genus * '' Babella'' Dall, & Bartsch, 1906 * '' Bartrumella'' Laws, 1940 * '' Besla'' Dall & ...

Odostomiinae
Odostomiinae, ''Odostomia'' snails and their allies, is a taxonomic subfamily of minute parasitic sea snails. These are marine heterobranch gastropod mollusks, or micromollusks, in the family Pyramidellidae. Taxonomy The subfamily Odostomiinae has been recognized as monophyletic. It includes the tribe Liostomini, a name given to those genera which have an intorted protoconch. The rest of the genera however do not form a single monophyletic taxon. Subfamily Odostomiinae has been classified as one of eleven recognised subfamilies of the very voluminous gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg 1997): Odostomiinae, Turbonillinae, Chrysallidinae, Cingulininae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae. In the taxonomy of Bouchet & Rocroi (2005), this subfamily also comprises the subfamilies Chrysallidinae, Cyclostremellinae and Odostomellinae, that they have downgraded to the rank ...

Pyramidellidae
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs. The pyram family is distributed worldwide with more than 6,000 named species in more than 350 nominal genera and subgenera. This family of micromollusks has been little studied and the phylogenetic relationships within the family are not well worked out. There is an absence of a general consensus regarding which species belong to a specific genus or subgenus, contributing to much confusion. Schander (1999) names more than 300 supraspecific names. As there has been no serious generic revision of the genera worldwide, generic polyphyly can be expected to be rampant throughout the family. However, the family itself is deemed monophyletic. However a study in 2011 seems to indicate that this family is deeply nested within the Pulmonata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cingulininae
Cingulinini is a taxonomic tribe of very small sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies. Taxonomy Cingulininae was first introduced by Saurin in 1959, and according to Schander, Van Aartsen & Corgan (1999) it comprises seven genera; '' Cingulina'', '' Cinctigua'', ''Coemansia'', '' Paracingulina'', ''Polyspirella'', '' Pseudocingulina'' and '' Puncticingulina''. As Cingulininae it has been one of eleven recognized subfamilies of the gastropod family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997), the pyrams and their allies. The other 10 subfamilies are Odostomiinae, Turbonillinae, Chrysallidinae, Cyclostremellinae, Sayellinae, Syrnolinae, Eulimellinae, Pyramidellinae, Odostomellinae and Tiberiinae. In the taxonomy of Bouchet & Rocroi (2005), this subfamily Cingulininae has been downgraded to the rank of tribe Cingulinini and belonging to the subfamily Turbonillinae.

Babella Caelatior
''Babella caelatior'' is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies. The species is one of twelve in the gastropod genus '' Babella''. Description The milk-white shell has an elongate-conic, turreted shape. Its length measures 4.4 mm. The three whorls of the protoconch are small, helicoid, rather loosely coiled and elevated. They have their axis at a right angle to the axis of the later whorls and about one-third immersed in the first of them. The nine whorls of the teleoconch are flattened, strongly sculptured, with axial ribs and three spiral keels. There is a strong, rounded, rather broad spiral keel on each side of the deeply sulcate periphery. The peripheral sulcus is about as wide as a keel and marks the path for the shouldered and crenulated summit of the succeeding whorls. A second deep spiral sulcus, equal in width to the peripheral one, is situated just posterior to the posterior keel, and this marks the ...

Schander
Carl Fredrik Christoffer Schander (21 May 1960 – 21 February 2012) was a professor in marine biology at the University of Bergen, Norway. He was also a thematic leader at the Centre of Excellence in Geobiology. His doctoral thesis (1997, University of Gothenburg, Sweden) explored the evolutionary relationships of the parasitic marine gastropod family Pyramidellidae. He worked on marine invertebrates, mainly molluscs, and published more than 90 scientific papers in peer-reviewed journals, 76 are indexed in the Web of Knowledge, and fourteen of them have been cited ten or more times. According to his web page, he considered the goal of his research to be understanding the roles that evolutionary forces and phylogeny have played in creating organismal diversity. To help develop this understanding, he used phylogenetic analyses that integrated morphological, ultrastructural and molecular data. His research focused on molluscs and more specifically on the ectoparasitic pyramidelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysallida
''Chrysallida'' is a speciose genus of minute sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini.Spencer, H.; Marshall. B. (2009). All Mollusca except Opisthobranchia. In: Gordon, D. (Ed.) (2009). New Zealand Inventory of Biodiversity. Volume One: Kingdom Animalia. 584 pp Taxonomy The genus ''Folinella'' had two preoccupied names - ''Amoura'' De Folin, 1873 ''not'' J.E. Gray 1847, and ''Funicularia'' Monterosato, 1884 ''not'' Forbes, 1845. The genus ''Chrysallida'' Carpenter, 1856 has been used as a catchall, particularly in the European literature following a lead by Winckworth (1932), for most pyramidellids having both axial and spiral sculpture but having otherwise little in common with the Californian type species ''C. communis'' (C. B. Adams, 1852). A statement that this is incorrect was voiced by van Aartsen, Gittenberger & Goud (2000: 21) who nevertheless still used ''Chrysallida'' as the genus to ...

Babella
''Babella'' is a genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005).Bouchet, P.; Gofas, S.; Rosenberg, G. (2018). Babella Dall & Bartsch, 1906. In: MolluscaBase (2018). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=588302 on 2018-01-08 Description The shell shows strong axial ribs between the sutures and three spiral keels, two of which are at the periphery, which falls in the deep sulcus between them, and one a little anterior to the middle of the base. Distribution The genus seems to be limited to tropical and temperate regions of the Pacific Ocean. Life habits Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae ''sensu lato'', they are ectoparasites. Species There are twelve known species within the genus ''Babella'', ...

Phillip Pearsall Carpenter
Philip Pearsall Carpenter (4 November 1819 – 24 May 1877) was an English minister who emigrated to Canada, where his field work as a malacologist or conchologist is still well regarded today. A man of many talents, he wrote, published, taught, and was a volunteer explaining the growing study of shells in North America. Life Philip P. Carpenter was born in Bristol, England on 4 November 1819. His father was Lant Carpenter, a notable educator and Unitarian minister. His mother was Anna or Hannah Penn, daughter of John Penn and Mary. Anna was christened on 11 May 1787 in Bromsgrove, Worcester.Carpenters' Encyclopedia of Carpenters 2009, DVD format.

Bartrumella
''Bartrumella'' is a small genus of miniature sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005). Etymology The genus is named after Professor and Mrs. John Arthur Bartrum (1885–1949), of Takapuna, Auckland. Shell description The shell of ''Bartrumella'' is high spired with a well-developed columellar lamella, which gives the appearance of a tooth in the aperture. There are axial ribs and fine spiral sculpture in the form of raised intercostal threads which are only visible through a hand lens or microscope. The spiral sculpture is present on all whorls and on the base. This sculpture is stronger towards the apical side of the whorls, and in that area there are nodules where the spiral and axial sculpture cross. The axial sculpture evanesces gradually on the base. The protoconch is intorted (planorboid). The original description of the genus and type species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
