''Tritonium'' is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails. The genus name Tritonium has been given twice to species with a different type species : * ''Tritonium'' O.F. Müller, 1776 : type species ''Buccinum undatum'' Linnaeus, 1758 (given by Stewart in1926); this makes this name an objective synonym of ''Buccinum''. * ''Tritonium'' Röding, 1798 : type species : ''Murex tritonis'' Linnaeus, 1758 (given by Cossman in 1903); this makes this name an objective synonym of ''Charonia'' Gistel, 1847. Neither of these original names is valid. Confusion increased when during the 18th and 19th century, authors added species but didn't specify to which ''Tritonium'' they belonged. The authors of the World Register of Marine Species (WoRMS) have arbitrarily attributed the species now placed in Buccinidae, Muricidae, and other neogastropod families, to ''Tritonium'' O.F. Müller, 1776. The species now placed in Ranellidae and Bursidae, have been attributed to ''Tritonium'' Röding, 1798.〔 ==Species== Some of the species that used to be included within the genus ''Tritonium'' : * ''Tritonium clathratus'' (Linnaeus, 1767): synonym off ''Boreotrophon clathratus'' (Linnaeus, 1767) * ''Tritonium submuricatum'' Schrenck, 1862: (species inquirenda) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tritonium」の詳細全文を読む スポンサード リンク
