Raphitoma Purpurea
''Raphitoma purpurea'' is a species of sea snail, a marine gastropod mollusk in the family (biology), family Raphitomidae. This species forms a complex with ''Raphitoma bourguignati'' (Locard, 1891), ''Raphitoma atropurpurea'' (Locard & Caziot, 1899), and ''Raphitoma digiulioi'' Pusateri & Giannuzzi Savelli, 2017. Description The length of the shell varies between 9 mm and 24 mm, its diameter between 4.9 mm and 9.5 mm. (Original description) The species shows a very rugose, fusiform and robust shell. It has a of a dark purple colour with sometimes a few spots or blotches of white. It contains nine or ten Whorl (mollusc), whorls, rounded, and tapering to an extremely fine, sharp Apex (mollusc), apex. They contain nineteen or twenty ribs, running a little oblique to the right. They are crossed by numerous sharp, elevated ridges, which rise into angles upon the ribs, making the shell very rough, and giving it a cancellated appearance. The Aperture (mollusc), ap ...

Raphitoma
''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 ...
