Help identifying these shells

[wbaltz]

Hi all, here are pictures of 2 different shells, could anyone tell me what they are?

Thank you!

Hi wbaltz,
#1 and #4 should be Cypraea tigris.
Concerning #2 and #3, for me it's impossible to be sure. I'd need larger pictures and a picture of the aperture (the opening). Sorry. Perhaps family Tonnidae.
Kind regards: wolf

Yes Tonnidae (Tun Shells) for #2 and #3 but more detail would be needed to be sure of the species.

Thank you all, I'll repost with better pics, and a ruler to help.
Again, thank you very much!
