The cylindric shell is shortly rimate, from cinnamon-brown 

 to cinnamon colored, the lighter specimens sometimes showing 

 the columellar axis faintly through. Typically it is rather 

 coarsely striate, but this is individually variable in the lots 

 seen. The embryonic whorls are irregularly, densely but 

 shallowly pitted, as in the P. signata series. The last whorl 

 is somewhat compressed towards the narrow, rounded base, 

 and generally very superficially furrowed over the lower 

 palatal fold. It is slightly swollen before the contraction 

 preceding the lip. The aperture shows an angular nodule 

 connected with the termination of the lip (sometimes nearly 

 obsolete) ; a deeply placed parietal lamella, not very long; a 

 small, deeply immersed columellar tubercle, and a short, 

 deeply placed low^er-palatal fold, almost basal in position (and 

 sometimes wanting). Parietal callus thin. The peristome is 

 rather narrowly reflected and is thickened within.
