Can someone confirm what these are?

I went in asking for Trochs, and at the time they were gathering them to me they looked correct. I have a couple in my smaller tank but they were a bit larger and they have this banded pattern on the bottom. I think I got Astrea or Turbo's rather than the Trochs I asked for.

Well that's great to know, I thought maybe a banded troch of some type. Glad I didn't get screwed.
