Hi,

Could anyone help me to identify these 3 shells collected on Tamarindo beach (Costa Rica)

 Cowrie #1 --> http://www.badongo.com/fr/pic/3138455
 Cowrie #2 --> http://www.badongo.com/fr/pic/3138456

 Shell #3  --> http://www.badongo.com/fr/pic/3138463
           --> http://www.badongo.com/fr/pic/3138465

Thanks a lot

#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.

Thank you for your answer

Yes the 3 species were found on the same beach on the pacific coast
