Description

The height of the shell attains 1.5 mm and its diameter 4 mm. The white shell has a plane-discoidal shape with 5 whorls. The species is beautifully cancellate and sculptured, though more or less smooth below the periphery and around the narrow but deep umbilicus. The whorls are all channeled at the sutures, very distinct (seen with a lens) on the two apical whorls. The penultimate whorl contains one keels and the body whorl three keels. The oblique aperture is oval.[3]

Distribution

This species occurs in the subtidal zone of the Persian Gulf
