 of preceding authors, these being so vague and loose as 

 to give a very imperfect idea of the shell intended to be 

 represented. It is possible that some deformity caused 

 the remarkable appearance noticed by him in his specimen. 

 On reviewing the preceding descriptions, I think I am 

 justificed in concludmg, that since the time of Buonanni 

 this shell has been rarely seen, and that the descriptions 

 in the books are mere copies, one from another, down to 

 Lamarck, who possessed a small specimen- The great 

 size and beauty of this species induced me to suppose that 

 conchologists would be gratified to see a new and correct 

 figure, (see plates V. h VI.) and a more perfect descrip- 

 tion, which I now add.
