Smooth form found at 12m deep, near Posidonia field, Vouliagmeni area, Attikí, SE. Greece. 2,6-3,2mm. These shells match the description given by Philippi: « Testa oblongo-turrita, laevissima, tenui, pellucida, virescenti-hyalina, strigis rufis longitudinalibus radiatim ornata, anfractibus superioribus obsolete costulatis, labro simplici, tenui. » – R. A. Philippi: Enumeratio molluscorum…, Berlin 1836-1844, p. 152.

The differences with lineolata are subtle: lineolata has more or less opisthocline brown bands that are located between the radial costae, and the protoconch is often stain in some dark purple; radiata, for its part, shows randomly arranged bands, often prosocline, that can pass over the costae, and its apex is pale. All the other features seem too much variable to be of reliable use.
