Xenophora Robusta
''Xenophora'', commonly called carrier shells, is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Xenophoridae, the carrier snails or carrier shells.WoRMS (2012). Xenophora. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138664 on 2012-06-28 The genus ''Xenophora'' is the type genus of the family Xenophoridae. Etymology The name ''Xenophora'' comes from two ancient Greek words, and means "bearing foreigners", so-called because in most species the snail cements pieces of rock or shells to its own shell at regular intervals as the shell grows. Description The shells of species within this genus vary from small to large (diameter of base without attachments 19–90 mm; height of shell 21–60 mm), depressed-conical, with narrow to very narrow, simple peripheral edge, non-porcellanous ventrally. Foreign objects are attached to all whorls, with generally more than 30% of do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenophora Pallidula
''Xenophora pallidula'', the pallid carrier shell, is a species of large sea snail, a marine gastropod mollusc in the family Xenophoridae, the carrier shells. Description ''Xenophora pallidula'' are relatively small, averaging about 68-78mm in length and 72-82mm in width. These snails have a light appearance, usually white or off-white in color. These snails get their name from the Latin word, Xenophoridae which means “foreign carrying”. In other words, these species will attach objects like coral skeletons, fragmented shells, and other debris to the dorsal side of their shell. These attachments often create a radial pattern around the whorls. While this is a commonality amongst the species in this family, ''Xenophora pallidula'' are known to cover more of their shell than other species in the family, with over half their shell hidden. And as the organism grows, there will be more and larger foreign material attached. This is not energetically favorable as the snails secrete ...

Xenophora Crispa
''Xenophora crispa'', the Mediterranean Carrier Shell, is a species of large sea snail, a marine (ocean), marine gastropod mollusk in the family (biology), family Xenophoridae, the carrier shells. Fossil record There are currently 16 known species in the genus, Xenophora. Fossils of ''Xenophora crispa'' are found in marine strata of Pliocene of Italy and Spain (age range: from 3.6 to 2.588 million years ago.). The Pliocene stage is the last stage of the Tertiary period before the Quaternary ice ages. This stage was the final of global cooling. Fossils of the genus ''Xenophora'' are found in marine strata from Cretaceous to Quaternary (age range : 89.3 to 0.012 million years). Although ''Xenophora crispa'' are found specifically in Italy and in Spain, fossils from the genus ''Xenophora'' can be found all over the world.

Xenophora Corrugata
''Xenophora corrugata'' is a species of large sea snail, a marine gastropod mollusk in the family Xenophoridae, the carrier shells. Description The length of the shell attains 35 mm, its diameter 38.5 mm. The spire is moderately high, broadly convex, bearing strong diagonal wrinkles. The base is deeply concave, its surface covered by close-set spiral ribs that are beaded by low curved radials, resulting in a corrugated surface. Distribution Species have been found in Fiji, Australia, Japan, and the Indian Ocean. Fossils have been found in Pliocene strata in Fiji Fiji, officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about .... References External links Ladd, H.S. (1977).

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Ignaz Von Born
Ignaz Edler von Born, also known as Ignatius von Born (, , ) (26 December 1742 in Alba Iulia, Grand Principality of Transylvania, Habsburg monarchy – 24 July 1791 in Vienna), was a mineralogist and metallurgist. He was a prominent freemason, being head of Vienna's lodge and an influential anti-clerical writer. He was the leading scientist in the Holy Roman Empire during the 1770s in the Age of Enlightenment. His interests include mining, mineralogy, palaeontology, chemistry, metallurgy and malacology. Biography Born belonged to a noble family of Transylvanian Saxon origin. He started school in his hometown, then was educated in a Jesuit college in Vienna, but left the Jesuits after sixteen months to study law at Prague University. He then travelled extensively to present-day Germany, the Netherlands, and France, studying mineralogy, and on his return to Prague in 1770 entered the department of mines and the mint. In 1776 he was appointed by Maria Theresa to arrange the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology, but also published a major work on Diptera of Chile. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich P ...
