Cassis madagascariensis: C. spinella Clench, 1944, was named as and is often treated as a subspecies of C. madagascariensis, but they occur sympatrically, so C. spinella is either a synonym or a separate species. If it proves to be a separate species, Cassis rotundata Perry, 1811, may be an older name; see Petit (2003).
