Description

edit

The size of the shell varies between 18 mm and 30 mm. The narrowly perforated shell has a conoidal shape. It is whitish-ashen, ornamented with undulating, oblique, radiating chestnut or blackish stripes. The spire is acute. The shell contains 7 whorls. The first whorl is eroded, the remainder are angulated and nodulose above. Above the carina the shell is obliquely nodulose, below the carina spirally lirate with 4 lirae. The body whorl is biangular, convex beneath, and has 7 concentric brown-spotted lirae. The aperture is subquadrate. The white columella is arcuate, sinuous, and below strongly truncate-dentate.[5]

Distribution

edit

This species occurs in the Persian Gulf and in the northwest Indian Ocean.
