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.
