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 basally. 



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. (Crosse.)

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.
