PLATE CLXXVIH. 



We feel a much slighter degree of hesitation in admitting this to be 

 the Shell meant by Mr. Adams, in the paper above quoted, than 

 the preceding species ; notwithstanding that our Shell has a greater 

 number of whorls ; the outline of his figure is rude, and far from 

 characteristic of the shell. — Our specimens are from Anglesea, as 

 before mentioned. It is represented both of the natural fize and mag- 

 nified, in the plate.
