What snail is this?

[Joevember]

I found a couple of these little guys in my sump glass and wanted to know if I should chuck them or keep them in my display. I only have nassarius snails in my display right now, and this is not one of them. As you can see they have a zig-zagging brown and white pattern on the shell.

Looks like it might be a collinista.

Thanks, I'll put them in the display, but I just found another in it already so no point in isolating them in the sump.
