P. KANALENSIS (Crosse). PI. 23, figs. 1, 2, 3. 



Shell imperforate, ovate-pyramidal, quite solid. " The spire is 

 long and somewhat subulate ; the last whorl is subcompressed, per- 

 ceptibly angular at the sides, as in P. alexander, and it is widest nearer 

 the base than in most of its allies ; the earlier whorls are whitish 

 and denuded, the following ones covered with a chestnut epidermis. 

 The peristome is ivory white or orange-tinted yellow; aperture a 

 more or less purplish orange shade. Columellar fold and parietal 

 tooth only moderately developed." Whorls 6J to 7, but slightly 

 convex. 



Alt. 81, diam. 40, length of aperture with perist., 46 mill.

The slender, almost acuminate spire is characteristic. The lip is 

 thicker than in P. souvillei. Fig. 2 is a copy of Crosse's figure of 

 his type. 



Var. tchioensis Kobelt (PI. 22, figs. 1, 2). Shell imperforate, 

 long-ovate, compressed, rather solid, not very thick, rudely ctriate or 

 scarred malleate ; whitish, covered with a greenish-chestnut epider- 

 mis. Spire convexly conic, denuded, buff, the apex slightly obtuse. 

 Whorls 6J, convex, separated by an impressed rather irregularly 

 margined suture, regularly increasing, the last scarcely inflated, 

 elongated, compressed, nearly double the length of the spire, scarcely 

 ascending in front. Aperture vertical, long-ovate, acuminate above,
