Minolia
''Minolia'' is a genus of sea snails, marine gastropod mollusks in the family Solariellidae. A. Adams named the genus from Mino-Sima, the little island near Niphon (Japan) 〔(Various authors (1860) The Annals and magazine of natural history 3rd ser. v. 6 )〕 ''Minolia'' was in older textbooks regarded as a subgenus of ''Margarita'' Leach, 1819 (itself now a synonym of ''Margarites'' Gray, 1847). ==Description== The thin, delicate, smooth shell is depressed and widely umbilicated. The whorls are rounded or angulated. The spire is depressed. The sculpture is finely decussated. The aperture is circular. The outer lip and columella thin, simple, acute. The umbilicus is simple and contains no spiral, callous internal funicle or rib.〔(Tryon (1889), Manual of Conchology XI, Academy of Natural Sciences, Philadelphia )〕
