2. I changed this shell as Ergalatax margariticola, but I think the ID is wrong.

1. This is one of the hundreds of different forms of Liguus fasciatus.  You would really need a specialist to tell you what form this is with certainty.  Form archeri or form caroli look like possibilities to me, but I am certainly not sure.

2.  This certainly is not an Ergalatax.  I don't think it is even a marine species.  It looks like a fresh water snail to me.  No idea of the name.

3.  Appears to be Chlamys (Brachtechlamys) vexillum
