256 American Seashells 



I inch in length, extremely close to carneum, differing only in being 

 larger, and in having a brown spot on the apex and 2 large chocolate spots 

 on the outer lip. There may be also 2 smaller spots at the anterior end of the 

 shell. Apparently rare and possibly a color form of carneum. I have seen 

 only 3 specimens.
