Snail Id Please

[sallen]

I have snails that the shells are black with a white patch on the back and ones that are in a pyramid sort of coned shaped shell, what type are they?????

Are the black ones round with a black foot? Or black & white striped? Could be margaritas, black footed turbos, or zebra turbos. The cone shaped are called astraea snails. Do you have pics?

no dont have pics but can get them tomorrow. the black one are a round shell, not a white stripe but more of a small patch on the butt of the shell. I did not mean the lethal cone snail either its more like a pyramid shape and a rounded at the bottom. thanks prom
