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 .
