2. P. CARINATUS (Pfeiffer). PL 15, figs. 62, 63. 



Shell conic, smooth, alabaster-whitish, ornamented with 

 wide, opaque-white bands at suture and periphery. Whorls 

 6~y 2 flat, the last acutely angular, about two-fifths the total 

 length. Columella subvertical, not reaching the base, very 

 shortly truncate; aperture subquadrangular, peristome sim- 

 ple. Length 31, diam. 17 mm., aperture 15 mm. long, 9.5 

 wide (Pfr.). 



Habitat unknown (Cuming coll.).

This form is evidently closely related to P. alabaster, and 

 in my opinion is a carinated subspecies of that. It differs 

 from the carinate variety of alabaster only in the more 

 strongly truncate columella. It has been referred to Liguus, 

 but erroneously. 



3. P. SOLIMANUS (Morelet). PL 15, figs. 64, 65, 66. 

 Shell rather solid, oblong-conic, thin but rather strong, 



SHioothish, .under a lens showing fine growth-lines and minute 

 spirals. White, typically with a brown line at the periphery, 

 a purple-brown columella and axial patch, and a purple- 

 brown band midway between axis and periphery; but S9me- 

 times the line and band are absent. Sutural margin white, 

 beaded below, smooth on the upper whorls. Spire conic, the 

 apex mamillar. Whorls 6% to 7, moderately convex, the last 

 obsoletely angular in front or rounded throughout. Aper- 

 ture quite oblique, colored within like the outside, the outer 

 lip acute; columella purple, twisted or nearly straight, ob- 

 liquely truncate below, the basal margin receding. 



Length 40, diam. 23 mm.
