Hi Xavier, not sure about the Tonna or Fissurella but the Columbellids look like Pyrene flava and the Nerita are Nerita histrio(=squamulata). If you have exact locality data it would be very helpful.

zenkiu and fisurrellas for puerto rico and tonna is thailandia

Hi Xavier, I have had another look at the tonna and I think they are T. canaliculata. As to the Fisurella, I can see at least 4 species. The picture is not clear enough to determine which species they are, I would need to see a much larger picture. Another alternative is if you could send some to me, maybe one of each form, then I could give you a positive i.d.
Dave
