have suggested a distinct separation of the Naticidae into four subfamilies: Ampullospirinae, Naticinae, Polinicinae and Sininae. This arrangement is mainly based on morphological data, such as details of the operculum including the material (calcareous in the Naticinae, corneous in the Polinicinae and Sininae) and size, and also the morphology of the shell. 2005 taxonomy The following four subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005): Naticinae Guilding, 1834 - synonyms: Neveritinae Gray, 1857; Choristidae Verrill, 1882; Euspiridae Cossmann, 1907; Mammillinae Iredale & McMichael, 1962; Eunaticinini Oyama, 1469 Sininae Woodring, 1928 - synonyms: Sigaretidae Gary, 1827; Cryptostomidae Gray, 1827 Globisininae Powell, 1933 Polinicinae Gray, 1847 Genera Genera in the family Naticidae include: Unassigned to a subfamily: Haliotinella Souverbie, 1875 Microlinices Simone, 2014 subfamily Naticinae Cochlis Röding, 1798 Cryptonatica Dall, 1892 Lunaia Berry, 1964: synonym of Natica Scopoli, 1777 Natica Scopoli, 1777 Naticarius Duméril, 1806 Notocochlis Powell, 1933 Paratectonatica Azuma, 1961 Proxiuber Powell, 1933 Stigmaulax Mörch, 1852 Tanea Marwick, 1931 † Taniella Finlay & Marwick, 1937 Tasmatica Finlay & Marwick, 1937 Tectonatica Sacco, 1890 subfamily Globisininae Falsilunatia Powell, 1951 Globisinum Marwick, 1924 subfamily Polinicinae Gray, 1847 Amauropsis Mörch, 1857 Bulbus Brown, 1839 Conuber Finlay & Marwick, 1937 Euspira Agassiz in Sowerby, 1838 Friginatica Hedley, 1916 Glossaulax Pilsbry, 1929 Hypterita Woodring, 1957 Kerguelenatica Powell, 1951 Laguncula Benson, 1842 Lunatia Gray, 1847 Mammilla Schumacher, 1817 Neverita Risso, 1826 - its subgenus or synonym includes Glossaulax Pilsbry, 1929 Polinices Montfort, 1810 Pseudopolinices Golikov & Sirenko, 1983 Sinuber Powell, 1951 Uberella Finlay, 1928 subfamily Sininae Calinaticina J.
