| F. E. Eames 1957 | Of small-medium size, form resembling that of the Cythara group of the Turridae. Protoconch naticoid, consisting of two and a half smooth, convex whorls. Last whorl forming four-sevenths of the height of the shell. Spire conic, consisting of three to four gently convex whorls which are moderately angulated at about two-thirds of their height ; sutures linear. Ornament delicately cancellate, Ficus-like, with tiny crenulations at the intersections of the axial and spiral elements. Last whorl oval, gently angulated adapically like the spire whorls and similarly ornamented ; base declivous and gently excavated at the origin of the moderately short neck ; axial ornament obsolete and spiral ornament irregular abapically. Aperture narrowly oval, with a short siphonal canal which is gently inclined to the left and flares a little at its deeply emarginate end. Columella gently concave, with one prominent fold (well inside the aperture) at half the height of the aperture proper. Columellar lip with thin callus which is moderately widely spread adapically but narrow abapically. No siphonal fasciole. Imperforate. Outer lip thin at edge, moderately convex medially, slightly concave at a level corresponding with that of the columellar fold, receding adapically, and with a very shallow, rounded sinus adjacent to the suture ; thickened internally and with prominent, short lirae. |
