Tbe largest, most strongly tubercled species. There is consider- 

 able variation in both form and color. Figs. 21, 22, of pi. 54, rep- 

 resent the form called S. obseura " Lam. " by Sowerby and others. 

 It is probably S. obscurata Lam.

 ably so, concave above the carina, plicate below the sutures ; aper-
