Class: Gastropoda

Image copyrights: Marco Ferrario

Size: 18-24.5 mm.

Color: Dark chocolate with the gemmules picked out in white; pillar light reddish brown; interior of aperture light purplish grey.

Shell of moderate size, ¾ - 1 inch in height, solid, drilliaform, with a tall spire but with a truncated anterior end. Sculpture of spiral keel and cord which are densely gemmulate at the points of intersection with numerous narrow flexuous axial ribs. The suture is submargined by a closely spaced pair of spirals, the upper one weak but the lower one massive. This is followed by the rather narrow, deeply concave shoulder sulcus which bears one or two fine spiral threads. Peripheral spiral on the site of a slight angulation, below which the spirals continue over the base to the anterior fasciole. There are from 1-3 spirals between the peripheral keel and lower suture or 7-10 between the periphery and the anterior fasciole; 5 or 6 weaker, linear-spaced, smooth cord on the anterior fasciole. Spire about 1½ times height of aperture plus canal. Anterior canal very short and weakly notched, with an oblique termination. In senile specimens the subsutural fold thickens at its termination to form a callosity, slightly restricting the U-shaped sinus which is at the termination of the one or two threads bisecting the shoulder sulcus.
