Snail Id by shell

[Elrodg]

What kind of snail has this kind of shell?
I had two of these lol guys and one died. They came from the ocean on some cultured live rock I got from Hawaii. They disappear into the sand as soon as they hit bottom.

I believe that is a cowrie. What type exactly I don't know

K. I have one left and he is never above the sand bed. Beautiful shell tho.

It's an Oliva sp. My best guess at species would be reticulata.
