Author: Cernohorsky, W.O.

Description

Shell to 44.0 mm in length, cylindrically-elongate. spire elevated and conical, teleoconch of 4.5-5.5 whorls, early spire whorls concave anterior to sutures, later whorls flat-sided or weakly convex, sutures narrowly sub-canaliculate; sculptured with spiral rows of granulose cords which number 4-5 on the penultimate and 28-35 on the body whorl, sutural nodules usually slightly larger; underlying the spiral sculpture and in line with the nodules are longitudinal lirae, interspaces of spiral cords with some axial striae, some individuals with additional axial growth-striae. Aperture considerably longer than the spire, narrow and smooth within, outer lip thickened and crenulate, columella calloused anteriorly and with 8-10 prominent folds, parietal wall with a callus-pad. Fawn to brown in color, frequently covered with a brown periostracum, aperture white, fawn or brownish.

Interchangeable taxa

The species is similar to P. crenulata but is usually larger in size with a more elevated spire and a sculpture of elevated, crisp and granose spiral threads. It is highly probable that the species also lives in the Philippines since it is known from Pliocene deposits of that area. The record of "Mulaku Atoll, Maldive Islands" in the BMNH requires confirmation.
