''Argyropeza'' is a genus of small deep-sea sea snails, marine gastropod molluscs in the family Procerithiidae.〔WoRMS (2010). ''Argyropeza'' Melvill & Standen, 1901. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=473011 on 2010-05-12〕 The name of this genus is derived from the Greek word ''arguropeza'' ("silver foot"), the epithet given by Homer to the sea nymph Thetis. == Taxonomy == The genus ''Argyropeza'' is closely related to the genus'' Bittium'', but the shells of species in this genus are thinner and more vitreous, and the suture is more deeply impressed. This genus is not well known and its systematic position has long been uncertain. It was sometimes assigned to the Litiopidae Gray, 1847 or to the Cerithiinae within Cerithiidae,〔Houbrick R. S. (1980) "Review of the deep-sea genus ''Argyropeza'' (Gastropoda: Prosobranchia: Cerithiidae). ''Smithsonian contributions to zoology'' 321 Washington. http://si-pddr.si.edu/dspace/handle/10088/5557〕 both belonging to the same superfamily Cerithioidea. The genus was moved to Procerithiidae because of its similarity to the fossil genus ''Crypaulax'' from the Triassic.〔Nützel A. (2002). "The late Triassic species ''Cryptaulax? bittneri'' (Mollusca: Gastropoda: Procerithiidae) and remarks on early aspects of the Mesozoic marine revolution". ''Paläontologische Zeitschrift'' 76(1): 57-63. 〕 This move means that the ''Argyropeza'' species are now considered to be living fossils.〔 According to the ''Taxonomy of Bouchet & Rocroi'' (2005) ''Argyropeza'' is in the subfamily Cryptaulacinae, within the Procerithiidae. According to Bandel (2006)〔Bandel K. (2006). "Families of the Cerithioidea and related superfamilies (Palaeo-Caenogastropoda; Mollusca) from the Triassic to the Recent characterized by protoconch morphology - including the description of new taxa". ''Freiberger Forschungshefte'' C 511: 59-138. (PDF ).〕 ''Argyropeza'' is in the newly described subfamily Argyropezinae Bandel, 2006, within the Procerithiidae.〔 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「Argyropeza」の詳細全文を読む スポンサード リンク
