Hi Toni, The first shell is Cypraea lurida rhodeislandensis Monfils, 2003. (hehe) In side view, I thought it was an immature Cypraea carneola, but fortunately you provided end views, and those four dark spots indicate it is not C. carneola. It looks to me like an immature Cypraea lurida, from the Mediterranean - a strange find indeed on a Rhode Island beach, and not a species commonly found in tourist shop assortments either! The limpet also looks like a Mediterranean or at least European species, probably Patella coerulea. The second shell is a Donax species. I can't say for sure which species it is, but at 27 mm, it's pretty big for the common American Donax variabilis, and I don't think it is that species. I wonder if it might be one of the several European species of Donax, given the apparent European source of the other two? I wonder how these might have ended up on your local beach (which is also my local beach)?? Regards, Paul M.
