Description Hedley:
The British Museum cotype is a small shell, conical, angled at the periphery and flattened on the base, the spire-whorls slightly bulging at their periphery. Whorls nine. Colour rose-red variegated by oblique flames of pale brown. Sculpture : the last and antepenultimate whorls have nine spiral strings, the outermost larger, apt to run in pairs and separated by spaces broader than themselves. They are crossed at a low angle by fine close threads which in their passage bead the strings and lattice the interstices. Base with half a dozen widely parted spirals ; here the radials are finer and closer and chiefly affect the interstices. Aperture subquadrate, columella abruptly truncate anteriorly. Within the base of the aperture is a bilobed callus ridge, a sort of doorstep, and within the left margin another mass of callus. Length, 10; breadth, 7 mm.
Description by Wilson:
Whorls nine; aperture subquadrate, a bilobed callus ridge within forming a "doorstep"; columella near vertical, with a central marginal thickening, abruptly truncate at its base; sculpture of spiral cords, nine on the penultimate whorl and sides of the body whorl, crossed by oblique threads which make the cords finely nodulose and the interspaces latticed; six widely spaced spiral cords and fine radial threads on the base. Rose-red, variegated by pale brown oblique flames. 10 mm high; 7 mm wide.
