 at first supposed to belong to Mr. Broderip's Cl'irngcl/ii 

 lata, but as that shell is imbedded in a different kind 

 of rock, and its tube is undescribed, it will be better to 

 treat the present as new. It differs from Clanii/clbt 

 aperta, in the much less open and reflected and umre 

 closely fluted character of its tube, as well a> in the 

 totally different character of its free valve.
