#1 Trivia radians (Lamarck, 1811)

#2 Jenneria pustulata (Lightfoot, 1786)

#3 looks like Marginella guttata (Dillwyn), but here's the problem. Are you sure these all came from the same beach? Because the first two are Pacific Coast species, while M. guttata is a Caribbean species. All three species can be found in Costa Rica but I would be surprised to find them all on the same beach.  <span class="petit">--Last edited by Paul Monfils on 2008-03-13 02:08:18 --</span>
