Cordieria
''Cordieria'' is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae.Bouchet, P. (2015). Cordieria. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=432436 on 2016-03-03 This genus is considered by the French malacologist Maurice Cossmann separate from '' Borsonia'', not on the basis of the columellar plaits alone, but mostly because of the shorter siphonal canal The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda. Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is ... and a number of other characteristics that he enumerates. Species Species within the genus ''Borsonia'' include: * † '' Cordieria fuscoamnica'' Darragh, 2017 * '' Cordieria horrida'' Monterosato, 1884 * † '' Cordieria iberica'' Rouault, 1848 * '' Cordieria ov ...

Cordieria Rouaultii
''Cordieria rouaultii'' is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.WoRMS (2015). Cordieria rouaultii. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=433399 on 2016-03-03 Description The size of the shell attains 14 mm, its width 5 mm. (Original description) The shell is yellowish white with a pink vertex and the interspaces between the ribs of a pink brown, generally rather pale. The shell contains seven or eight whorls, two of which belong to the nucleus. The nucleus is glassy polished, smooth, swollen, rounded, its second whorl with an obsolete peripheral keel . The remainder of the shell has a rather strong sculpture. The spiral sculpture consists of three or four strong and a few much finer ridges between the sutures and in front of the anal fasciole. On the body whorl these continue over the base and siphonal canal. The anal fasciole shows on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordieria Ovalis
''Cordieria ovalis'' is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae. Description The size of the shell attains 13 mm, its width 9 mm. (Original description) The small, oval shall has a short spire consisting of 4 rapidly diminishing whorls. The outline of the whorls is slightly convex. The oval aperture measures rather less than half the length of the shell. The outer lip is thick, the inner lip is not callous. The columella shows 3 distinct folds. The aperture is obtuse anteriorly. Each whorl has about 15 radial costae slightly raised and continuous from suture to suture. These costae are turned slightly backward. A number of sharp spiral threads, which, however, are interrupted, on the costae. The suture is impressed and not bordered. On the body whorl the costae decrease anteriorly, and are not distinct on the base. Many of the spiral threads, however, continue into the aperture. This shell, owing to the coarseness of its sculpture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raphitoma Hispidella
''Raphitoma'' is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. The type species ''Pleurotoma hystrix'' Cristofori and Jan, 1832 is a nomen nudum. It has been validated by Bellardi, 1847 as “''Pleurotoma histrix'' Jan.” Distribution This genus occurs in European waters, in the northern part of the Mediterranean Sea, and in the Atlantic Ocean off Cape Verde, West Africa and Angola. Taxonomy history The genus ''Raphitoma'' was created in 1847 by Luigi Bellardi (1818-1889) in his "Monographie des Pleurotomes fossiles du Piémont" for species in different groups without operculum. ''Raphitoma'' now contains many species formerly assigned to ''Pleurotoma'' Lamarck, 1799, ''Clathurella'' (Carpenter, 1857) and ''Philbertia'' (Monterosato, 1884). ''Philbertia'' was synonymized with ''Raphitoma'' in 1990 because Dr. Philippe Bouchet did not consider valid the subdivision of species into different genera solely on the basis of differences during ...

Borsonia
''Borsonia'' is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae. Description The fusiform shell has medium to small size. It has an elevated spire and a well-marked siphonal canal. The whorls of the spire are usually angulated near the middle. On this angle they show elongated nodes or axial ribs. These nodes disappear almost completely at the last section of the body whorl. The sutures are distinct. The aperture is elongate and is about half as long as the shell. The simple outer lip curves back near the top and forms a deep notch. The columella is nearly straight and has none, one or two strong plications on the upper half. The anal sinus of the outer lip is not deep The sinus area between and the strong sutural cord are well excavated. There is an opening in the infrasutural depression of the body whorl. Distribution At considerable depths in the subtropical and temperate waters of the Pacific Ocean and the Atlantic Ocean; in shallower boreal w ...
