Turbo (Leptothyra) pillula [sic] (non Liotia pilula Dunker, 1860 )—G.B. Sowerby (III), 1897: 17.

Turbo natalensis —Barnard, 1963: 213 (in part, incorrect synonymy).

Neocollonia ponsonbyi — Kilburn, 1974: 193, figs 5a, 6 ( radula ).

Distribution. Durban to central Transkei (Hluleka), exceptionally to East London; beach-drift to 85 m (no data for living specimens).

Notes. When describing this species, G.B. Sowerby (III) obviously considered it to be distinct from Bothropoma pilula (Dunker, 1860) and it has generally been considered so ever since. However, this question needs to be investigated in more detail. Inexplicably, Barnard (1963) treated this species as a synonym of Turbo cidaris natalensis .
