P. KANTAVUENSIS (Crosse). PL 39, fig. G6, 67. 



Shell almost covered perforate, cylindric-fusiform, rather solid, 

 longitudinally wrinkle-striate, obsoletely submalleate ; rose-whitish 

 under an olivaceous-yellowish cuticle which is here and there zigzag- 

 streaked with whitish. Spire somewhat cylindrically conic, the 

 suture somewhat irregular, impressed. Whorls 5, a trifle convex, 

 the earlier three rose colored, the last descending, longer than the 

 spire, subcylindrical, a little compressed in the middle, slightly taper- 

 ing basal ly. 



Aperture ear-shaped, whitish inside, effuse at the base; peristome 

 white, broadly expanded, reflexed, the margins joined by a parietal 

 callus, outer margin subcompressed in the middle, flexuous, becom- 

 ing narrower toward its insertion above ; columellar margin with a 

 strong twisted fold. (Orosse.)

Closely allied to P. koroensis, but differing in the smaller size and 

 persistence of the cuticle. None but the original specimens are 

 known. Type in coll. of the Journal de Conchyliologie. 



P. KOROENSIS (Garrett). PI. 39, figs. 61, 62, 63, 64, 65. 



Shell imperforate or rimate, oblong and narrow, thick and solid. 

 Surface lusterless, dull pink-tinted, sometimes becoming pale-orange 

 toward the apex ; totally denuded of cuticle in adults, or retaining 

 only small shreds, the young covered with a thin, pale yellowish- 

 brown cuticle ; sculpture of irregular growth-wrinkles, and sometimes 

 a faint, subobsolete spiral corrugation. Apex obtuse, slightly over 

 two earlier whorls punctulate. Whorls about 5, at first but slightly 

 convex, the penultimate more swollen, last whorl compressed laterally, 

 more or less cylindrical, sometimes girded in and distorted. 



Aperture white or flesh-tinted within, ear-shaped ; outer lip mod- 

 erately expanded (sometimes reflexed), strongly thickened within, 

 white or dirty-yellowish, bent in near the middle. Columella with 

 a very strong spirally-entering fold.
