Gray Pygmy Venus

Sally Thomas: could it be glory-of-the-seas venus? my references say that gray pygmy venus is 1/2 "

I don't think it's a gray pygmy venus -- end of shell isn't squared off enough for me. Not sure about what else it could be -- I'll keep searching.

Paul Monfils: Hello Sharon,

Yesterday I visited your impressive website. I noticed that the shell you have listed as "gray pygmy venus" is actually the spiny paper cockle, Papyridea lata Born, 1778. I'll take a closer look at some of the others shortly, when I have a little more time.
Sure looks like he's correct.
