Mediterranean sand worm shells and an unknown Mediterranean shells

[lulu.shell]

The unknown Mediterranean snail is from the Ebro Delta, and the sand worm shells are from Cunit (Between Tarragona and Barcelona). Has anybody any idea what either are? The snail shell is quite small, as you can see.

Thanks!
