Description

edit

The length of the shell attains 32 mm.

The white shell is narrow and fusiform. The shell contains six whorls, of which two bulbous whorls in the protoconch. The whorls are extremely gradate with smooth ribs. The interstices are apparently likewise smooth, but with a powerful lens most delicate spiral striation is observable. With age, however, these striae wear off. The narrow aperture is oblong. The outer lip is thin.

This pretty little species is well differentiated by its four columellar plaits, all of equal size and similar convolution. The ochre-brown spotting on an otherwise pure white ground, principally at the point of junction of the outer lip with the body whorl and on the summit of every third rib just below the sutures on the penultimate and body whorls, is peculiar.[2]

Distribution

edit

This marine species occurs in the Persian Gulf.
