Actually, Gary, all I said was, "How many shells have common names that
were borrowed from Latin genera?" A much broader topic than shells whose
"English common name [is] identical with the scientific name". This is a
good example of a general phenomenon: We remember by translating and
encoding information in our minds, not by recording it photographically.
 
Thanks for the support on "pecten," by the way. It's been an interesting
thread; I could not have predicted all the twists and turns.
