Proc. Pliilad. Acad., 43. 1861. 



Shell robust, conic cylindrical, with ten whorls, which are bi- 

 carinate by being deeply grooved immediately above the suture 

 and again in the upper half of the whorl. The ridge left between 

 these grooves is ornamented by ten strong, yellow, smooth, shining 

 tubercles; the upper edge of the whorl is again bevelled, forming 

 the second carina, which is not at all nodulous. Below the nodu- 

 lous carina on the body-whorl there are obsolete ribs, crossed by 

 four nodulous ridges, and below these there are eight others, some 

 of which are obscurely nodulous; on all parts of the shell not 

 occupied by the tubercles or carina there are numerous fine equi- 

 distant striae, requiring the glass to bring them to view. Aper- 

 ture small, outer line made oblique by the deep sinus of the thick 

 outer lip just below the suture ; pillar nearly straight, with a 

 strong callus. Color deep brown, with a lighter colored band 

 near the extremity of the canal ; beyond that, to the extremity is 

 again almost black. Allied to P. o?-nata, Orb.
