Cynisca gloriosa Bartsch, 1915: 163 , pl. 31, figs 6–8. Turton, 1932: 194. Type loc.: Port Alfred, E. Cape; holotype in USNM (250515). Syn. nov.

? Leptothyra eucosmia Turton, 1932: 177 , pl. 42, no. 1254. Type loc.: Port Alfred, E. Cape; type material probably in OXUM, but verification required.

? Cynisca formosa Turton, 1932: 194 , pl. 50, no. 1350. Type loc.: Port Alfred, E. Cape; type material probably in OXUM, but verification required.

Cynisca granulosa (non Krauss, 1848)— Turton, 1932: 194.

Cinysca granulosa (non Krauss, 1848)— Richards, 1981: 36 (in part), pl. 9, fig. 72. Kilburn & Rippey, 1982: 48 (in part), pl. 9, fig. 13. Steyn & Lussi, 1998: 28 (in part), fig. 91. Herbert & Warén, 1999: 223. Marais, 2011: 9.

Distribution. Southern Cape, from Port Alfred to False Bay; living LST and shallow subtidal.

Notes. Judging from the width of the umbilicus as shown in the original figures, Cinysca gloriosa ( Bartsch, 1915) is a strongly sculptured male specimen of C. spuria . Whether Turton’s C. formosa is also referable here is unclear. The illustration provided indicates the sculpture to be more finely beaded than that of C. spuria . Leptothyra eucosmia Turton, 1932 is simply a juvenile Cinysca , in all probability C. spuria . After describing Turbo (Collonia) armillatus from Australia, G.B. Sowerby (III) later recorded it from Port Elizabeth (G.B Sowerby (III) 1892). This name does not seem to have been used subsequently for any Australian species and it is thus probable that the original material was mislocalised.
