Umbonium moniliferum

The solid shell is depressed with a very low, conoidal spire.

Its color pattern is yellow, pinkish or whitish, closely tessellated with purple-brown or bluish slate-color, the basal callus purplish flesh-colored.

Its surface is shining, polished, with spiral sulci above, generally 3–5 in number on the body whorl, often subobsolete.

The suture is sometimes margined by a row of prominent tubercles, 8 to 11 on the body whorl.

The shell contains about six whorls, the last rounded at the periphery, convex beneath.
