ID mavens,
I've got a beachworn orange-brown 15mm gastropod from the Pacific coast of
Costa Rica for which I'm not even certain of the family.
It's got reticulate sculpturing, fusiform shape, two columellar plications,
and a squared shoulder just below the suture. I don't see anything similar
in Keen's book.
Anyone wanna look, I can send a couple of scanned images.
Thanks,
David Kirsh
