Several varieties occur of tliis conical species, and some speci- 

 mens arc less angularly conical than others. Figures 93 and 94 

 wxre engraved with a view to describing the shell as a separate 

 species ; subsequent examination, however, proved it so near to the 

 variety figured at 101, and the gradation from that to the more 

 conical varieties appeared so complete, that it seems impossible to 

 separate them.
