Smith, 1901 ) Glyphis spreta E.A. Smith, 1901 : 104 , pl. 1, fig. 18. E.A. Smith, 1903a : 391 . Kennelly, 1964 : 53 , pl. 3, fig. 16. Type loc.: Mossel Bay, Cape Colony; six syntypes in NHM (NHMUK 1889.4.14.2406–2411), Salvador pers. comm. ( iii/2015 ); three syntypes in SAMC (2459). Fissurella neglecta ( non Deshayes, 1830)—G.B. Sowerby (III), 1889a: 12. Fissurella fimbriata ( non Reeve, 1850)—G.B. Sowerby (III), 1889b: 154. G.B. Sowerby (III), 1892: 48. Fissuridea spreta — Bartsch, 1915 : 177 . Diodora spreta — Viader, 1937 : 57 . Barnard, 1963a : 290 , fig. 22g . Kensley, 1973: 30, fig. 38. Christiaens, 1974 : 92 . Richards, 1981 : 33 , pl. 7, fig. 41. Kilburn & Rippey, 1982 : 36 , pl. 6, fig. 10. Steyn & Lussi, 1998: 10, fig. 13. Marais, 2011 : 27 . Distribution. South-western Indian Ocean, from northern Mozambique to W. Cape (Cape Agulhas); beach-drift to 260 m , but mostly less than 100 m (living LST to 62 m ). A record from Mauritius ( Viader 1937 ) requires confirmation. SUBFAMILY: EMARGINULINAE Children, 1834 1 Cornisepta McLean & Geiger, 1998 . Type species (o.d.): Fissurisepta antarctica Egorova, 1972 . Cornisepta onychoides ( Herbert & Kilburn, 1986 ) Fissurisepta onychoides Herbert & Kilburn, 1986 : 24 , figs 87–89. Type loc.: off Shixini Point, Transkei (32°31.2ʹS: 28°52.2ʹE), 300 m ; holotype in NMSA (C6365/T3017). Cornisepta onychoides — McLean & Geiger, 1998 : 24 . Distribution. Central KwaZulu-Natal (off Umlaas Canal) to southern Transkei (off Shixini Point); 250–500 m (no data for living specimens). Cranopsis A. Adams, 1860 . Type species (m.): Cranopsis pelex A. Adams, 1860 . McLean & Geiger (1998) treated Cranopsis as a full genus, but this was questioned by Aktipis et al . (2011). Molecular analyses based upon a broader sampling of species will be needed to clarify this. In Cranopsis the mantle skirt is split anteriorly, underlying the seam in the shell that extends ventrally from the foramen. Such a split is absent in Puncturella and the mantle skirt is entire ( Cowan & McLean 1968 ).
