Original description of Rostellaria ? lucida by Sowerby, 1815, p. 203:

• "Fusiform, longitydially ribbed, transversely striated; lip thick with an obscure sinus at the inferior edge, and a very short channel at the superior; beak straight, short?"
• "The surface of this species is glossy and covered equally with fine rising obtuse striæ, the ribs numerous and rounded, the whorls about eight, in the young shell the lip is not thickened; when the last whorl is about half-formed its growth is stopped, and the edge of the lip is inflected; it afterwards grows to its full size, and the lip thickens leaving the inflected part of the former lip in the form of a large rib about half a whorl from the end."
