Dr. Harry Lee, a nationally known malacologist, deserves much credit for this work. Thanks to him, we know the identity of many of the shells of Sunset Beach, NC. Information on how to find these shells in seaweed and sea drift from the eastern point of Sunset Beach is at: http://www.okeefes.org/Barrier_Islands/Sunset_Beach/Shells/Sunset_Beach_Shells.htm

Black lines on ruler visible in some images depict milimeters. Not all species have been photographed.

15. Noetia limuli (Conrad, 1832) -- These easily found shells have been extinct for one to two million years. Note: in comparing my hundreds of ark shells, the outstanding feature of this species is that it is wider than high. If you look at the arks above and below it on this webpage, you will see the difference.
