Herpetopoma
''Herpetopoma'' is a genus of sea snails, marine gastropod molluscs of the family Chilodontidae.〔Bouchet, P. (2010). Herpetopoma Pilsbry, 1890. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=391155 on 25 March 2013〕 In the past, this genus was often tretaed as a subgenus of ''Euchelus''. However, this genus may prove to be a composite taxon, given the diversity of the shell forms.〔( Herbert D.G. (2012) A revision of the Chilodontidae (Gastropoda: Vetigastropoda: Seguenzioidea) of southern Africa and the south-western Indian Ocean. African Invertebrates, 53(2): 381–502 )〕 ==Description== The shell has a turbinate-conic shape as in ''Euchelus''. The spire is elevated. The operculum is multispiral as in a typical ''Trochus'' and with more, less rapidly expanding whorls compared with ''Euchelus''.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia )〕 Species in this genus has typically two teeth, joined by a U-shaped notch, where the columella and the basal lips join.
