P.S.  For those of you who want to know what I will put on the customs slip
when I ship these shells, print your guess on the back of a twenty dollar
bill and send it to me at PO Box 94, Whitefield, ME 04353   A winner will be
drawn from the correct answers and sent a free bonus specimen of Donax
variabilis.  Multiple entries accepted.
