Taxonomic notes: This species is listed in Kay, 1979 as Hinemoa indica. However, the more elongate shells lumped with the species by Kay are actually Cingulina sp. #1 and the shell illustrated in Fig. 32 is of the latter species. It's listed at Oscilla pupu in Severns, 2011 but Oscilla pupu (Pilsbry, 1917) is probably a synonym of Ocilla indica. (John van Aarntsen, pers. com.)
