Differs from other members of genus in shell having peripheral angulation and protoconch microsculpture of pits arranged in axial bands. This species has a large, distinctive shell which has a weakly angled periphery and a weak columellar bulge. The female genital system is also distinctive in the female genital opening being a very long slit that extends well in front of the capsule gland (Fig. 96A), and the penis, although generally similar, has a minute distal papilla. In most other characters, this species somewhat resembles P. daveyensis and P. richardsoni.
