Shell, as shown by the internal casts, depressed globular or broadly 

 oblate in general outline, the volutions being very ventricose, and the spire 

 low, the inner volutions rising but very little above the outer ones, and the 

 base in the casts being quite short; volutions probably not more than three 

 and a half or four in number, and very rapidly expanding, so that the last 

 one forms nearly the entire btxlk of the shell, the outer one being slightly 

 angular in the upper part; aperture large, semilunate or semielliptical, as 

 wide as or wider than high, modified on the inner upper half by the pre- 

 ceding volution, and slightly extended below by the projection of the 

 short columella, upon which there appears to have been a strong, angular 

 ridge; surface marked by very strong, angular, spiral ridges with concave 

 interspaces; seven or eight of these may be counted below the angulation 

 of the outer volution, including the angle itself, and two or three smaller 

 ones above this point on large specimens; those below the angulation grad- 

 ually decrease in distance and become more and more oblique as they 

 approach the columella. On a single large distorted specimen which I 

 find in the collection of the Acad. Nat. Sci. Phila., identified apparently by 

 Mr. Gabb, there appears to have been rather strong, irregular, transverse 

 marks of growth crossing the spiral lines, possibly only an individual char- 

 acter, but I think probably organic and a specific feature. 



In its general foiTQ this species is somewhat similar to P. octolirata Con., 

 but differs in its much greater size,- lower spire, and shorter canal, as well 

 as in the slight angulation of the body whorl, which that one never shows. 

 I do not think it probable that this shell was congeneric with those upon
