On comparing Mr. Lea's original specimen with Forbes' paper, it becomes clear tliat his 

 determination of the Ancyloceras as being the same as Lea's species is incorrect. The 

 Ancyloceras has tubercles on the septate portion of the shell, and on the body chamber the 

 ribs are irregularly placed. This part is also not perfectly straight. Forbes' descrii)tion 

 and figure of his Hamites correspond exactly with Mr. Lea's fragment, now before me. I 

 have therefoi-e revised his determination.
