Description
As Harpa harpa, up to 7 cm, with 11-14 axial ribs and higher spire. Colour white with cream and pale brown banding. Columella with large, central purple blotch; aperture white.
The ovate shell is oblong. It is rather small and slightly elongated. The whorls of the spire are distinct and mucronated (= ending in an abruptly tapering point). The body whorl has eleven or twelve narrow and slightly elevated longitudinal ribs, the surface of which, of a yellow ground, is crossed transversely by a great number of very fine blackish lines, which approach alternately, two by two. The intervals of the ribs are marked with very thin and delicate longitudinal striae, and with brown and whitish lines undulating in bars. Sometimes one or two whitish bands are observed upon the body whorl. The aperture is ovate, alike whitish, with several small brown bands upon the edge of the outer lip which, externally, is covered by the last rib. The columella is almost straight and is marked with small brown spots.
