Description

The length of the shell varies between 10 mm and 20 mm. The discoidal, depressed, smooth, shining shell is covered-perforate. The six whorls, are, under a lens, very minutely, obliquely striate. The earliest whorls are whitish, spirally obsoletely sulcate, the remainder are pale flesh-colored, ornamented with a subsutural linear zone and oblique brown spots. The body whorl is dilated, obtuse in the middle, spirally trilineate (one line above, two at periphery), somewhat convex beneath, with two zones of brown spots. The aperture is transverse, and scarcely sulcate within. The columella is nearly horizontal, twisted above, truncate beneath. The columellar callus forms a coating to the extremely oblique umbilicus.

Distribution

This marine species occurs off Taiwan, off the Ryukyu Islands, in the East China Sea and off the Philippines.
