The animals is similar in shape to P. auriformis. The shell is reduced to a flattened body whorl. It is sculptured on the outer surface by strong spiral pitted grooves producing a punctate pattern. The inner surface of shell is heavily glazed. It is white, with a sunken spire, large body whorl, convex and open from below. The outer lip extends beyond the spire, forming a spinous process. Spine often denticulate through the extension of strong spiral ridges that sculpture the upper end of the shell. The gizzard is relativley large with three identically shaped calcareous plates.
