Please excuse my earlier post of a single shell, today.

I have two shells from the Archerd Shell Collection, of which the ID
accuracy may be questionable. I don't find anything on the brown,
striped Crepidula_spp.; nor do I, for the Trocho_cochlea_crassa
(Pult, ___) which is from Cascais Bay, Lisbon, Portugal. The shells
may be viewed at:

I would be grateful for any assistance.
