Lehmann's Top Shell. Shell elongate-conical, imperforate, thick, whitish or olive decorated with numerous narrow olive brown or reddish-brown axial stripes; spire long, apex subacute, whitish; sutures moderately impressed whorls seven, flat or concave below the sutures, convex and swollen at the periphery and above each suture, encircled by numerous fine lirae; last whorl a little dcflexed at the aperture, subangular at the periphery; aperture rhomboidal, less than half the total length of the shell; peristome rather thin, acute edged by a row of red dots thickened a little distance within, the thickening finely crenulated, columella vertical, marked with crimson at the outer base. Diameter 12 mm., height 1.6 mm.

Distinguished from the South Australian P. lesueuri chiefly by the colour pattern of regular narrow axial stripes. This variant P. lehmanni is dominant in South Western Australia, but very rare in South Australia, a few specimens having been taken at Port Lincoln.
