Differs from the shell given by Kiener as young B. marginula- 

 tum by its more ventricose form, much coarser sculpture, less 

 elongated spire, and the presence of the posterior lamina on the 

 pillar. It may be compared with Bucc. Gruneri, Dunker.

Much resembling Bucc. cocci?iella, but smaller, less ponderous, 

 more slender, the last whorl proportionally larger, the ribs less 

 numerous, but the revolving lines more so. 



Nassa mendica. Testa parva, rudis, solidula, elongata, rufo-

A somewhat rude shell, very variable in its surface, being the 

 Pacific analogue of N. trivitlata, Say. It is more solid, more 

 undulated, less shouldered, its pillar lip more protracted, and its 

 aperture smaller. It is also closely allied to N. perpinguis, 

 Hinds, from the California coast, though differing essentially from 

 his description and figure.
