Re: more shell form Pacific Costa Rica shores to identify...better photos....tha
6402  I believe this is a badly beachworn Jenneria pustulata

0023  The interior of this shell, including the hinge structure, looks like a Laevicardium, but the exterior looks a bit strange.  Still, my best guess has to be Laevicardium elenense, even though it doesn't look too much like my specimens of this species.

0647  This appears to be an immature specimen of Ellobium stagnalis

0943  This is a species of Veneridae.  There are quite a few species in your area, but only a couple of them have such a glossy exterior, mainly species of Megapitaria.  I think this is a juvenile specimen of Megapitaria squalida, which can grow up to 120 mm in length.

1053  Oliva sp.  Too worn for positive ID.  The slight hint of a tented pattern (or is that my imagination?) and the low spire suggest the possibility that it might be a juvenile Oliva porphyria.  The other Oliva species with angular patterns usually have a fairly high spire.  Anyway, All I'm sure of is - Oliva.

1181  Appears to be Mactridae, probably genus Mactra, species uncertain.

1647  Trivia radians, in my opinion.

8616  Cypraea cervinetta

9194  family Veneridae, genus Chione, probably Chione amathusia
