This unfigured species is probably a form of, or very 

 closely related to P. micans, which has a slightly larger 

 aperture, but no other difference so far as the description 

 shows.

The shell is oblong-conic, openly rimate and perforate, thin, 

 pale yellowish-corneous throughout, imperfectly trans-parent, 

 not glossy. Spire conic, the apex slightly obtuse ; whorls 4% 

 to 4%, all convex; 2^/2 embryonic whorls sculptured with 

 punctured engraved spirals, following whorls marked with 

 growth-lines and fine engraved spirals, which continue strongly 

 and evenly developed on the last whorl, which is especially 

 convex above the periphery and at the base, and somewhat 

 tapering between. The aperture varies from moderately to 

 very slightly oblique, ovate ; outer and basal lip narrowly re- 

 flexed, slightly thickened within except at the posterior curve 

 of the outer lip where it is thin; on the columellar side the 

 thickening extends about half way up to the insertion. The 

 columellar lip is dilated and two-branched above. 



Length 14, diam. 8, aperture 7.8 x 5.2 mm. 



Length 13, diam. 7, aperture 7 mm.
