Monograph of the Cones of North America. 125 



North American seas : this is no doubt a mistake. Lamarck seems 

 to imply that the conus daucus, conus nivosus, and some others, 

 may also be found on our coast ; but as we have no personal 

 knowledge of these facts, we shall not insert them in this mono- 

 graph. Mr. J. Finch has in his possession the cast of a cone 

 which he discovered along the Chesapeake and Delaware canal, 

 but this does not furnish characters sufficiently distinct to make 

 out a satisfactory description.
