1 money cowrie, Cypraea moneta
2 keyhole limpet, Fissurella, not sure of exact species
3 this is an operculum, which is a sort of "door" the snail uses to close the aperture of its shell when it withdraws inside. not certain which species of snail it came from, though it was from the turban shell family

Hi Paul,
#3: might be family Neritidae, concerning the form of the operculum and the spine?
Kind regards: wolf

Yes indeed wolf. Thanks. I guess I shouldn't try to ID shells at 2:00 AM :-)
