Description

The length of the shell varies between 15 mm and 25 mm. The thin, imperforate, elongated shell has a turreted shape. This is a variable species in size and coloration. It is polished and shining, white, creamy or pink, with spiral bands of pink, purplish-red or purplish-brown, or narrow oblique zigzag stripes of pinkish-brown, usually with a narrow subsutural fascia of dark or pinkish. The spire is elevated and slender. The dark apex is a little blunt. The about 9 whorls are, very slightly convex, and a trifle impressed below the sutures. The surface (under a lens) is very densely, finely spirally striate. The body whorl is rounded. The base of the shell shows a few concentric, separated, impressed lines. The aperture is ovate. The thin outer lipis acute. The sinuous columella is arcuate above and narrowly reflexed, obliquely truncate below.[3]

Distribution

This marine species occurs in the Gulf of Aqaba, off Mozambique and off New South Wales to South Australia, and off Tasmania
