The Melongenidae, the crown conchs, busycon whelks and their relatives, are a taxonomic family of large to very large marine gastropods in the clade Neogastropoda. == Taxonomy == The genera ''Busycon'' and ''Busycotypus'' were previously placed in the Melongenidae.〔 However, based on their digestive systems and on cladistic analysis by Kosyan & Kantor (2004),〔Kosyan A. R. & Kantor Yu. I. (2004). "Morphology, taxonomic status and relationships of Melongenidae (Gastropoda: Neogastropoda)". ''Ruthenica'' 14(1): 9-36. (abstract and preview )〕 these two genera have been moved to the family Buccinidae. According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005), the family Melongenidae consists of two subfamilies: * Subfamily Melongeninae Gill, 1871 (1854) - synonyms: Cassidulidae Gray, 1854 (inv.); Galeodidae Thiele, 1925 (inv.); Volemidae Winckworth, 1945; Heligmotomidae Adegoke, 1977 * Subfamily Echinofulgurinae Petuch, 1994 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「Melongenidae」の詳細全文を読む スポンサード リンク
