36 Remarks on Certain Species of 



■when he published its description. In his remarks on that 

 species he says, "several specimens were found, but all dead 

 shells, and destitute of their epidermis." K Say's types of E^. 

 porcina were young shells, they were surely rather of H. inflecta 

 than of Mrsuta. I have specimens of the former from Michigan, 

 sent to me by Professor Winchell, and from Georgia by Bishop 

 Elliott, which, as regards the epidermis, lead to that conclusion. 

 I anticipate, however, that further researches w^ill prove this 

 to be a distinct species. The publication here of Say's descrip- 

 tion and figures will surely induce inquiry.
