All, On a recent trip I was able to do some shell collecting in New Jersey (Sandy Hook and Keyport beach). One of the finds was a 3 to 4 inch mussel with a brachidontes appearance. I collected several specimens, so it should not be uncommon, however, I do not seem to find in the general shell literature. Has anybody from New Jersey and surrounding any idea which species this is? I appreciate the help! Regards > Fred L.J. Vervaet Amsterdam, The Netherlands
