Description
A medium-sized, smooth, and highly glossy marine gastropod shell. It exhibits a cylindrical-ovate shape with a relatively short, conical spire and a large, dominant body whorl. The aperture is long and narrow, extending almost the full length of the shell. The columella features several distinct folds near the base. The shell's surface is polished, and its coloration consists of a pale cream to off-white ground color, adorned with irregular, scattered purplish-brown and yellowish-brown spots and blotches. The interior of the aperture is a pale orange-yellow.
