Hello

I have found in some years about 50 Haliotis from Ibiza, Balearic Islands.

I have checked some books & pictures and i am pretty sure every piece is
a Haliotis tuberculata.

I have seen some pictures of H. named a H. lamellosa. On some pictures you
can
see its different but on many other i am somewhat sure they show a
tuberculata form.
There are also some named as H. tuberculata lamellosa using lamellosa as
subspecies.

Are there more varieties out? I have F. Nordsiecks book about the european
seashells (ISBN 3-437-30360-0) and he mentioned there lamellosa with a note
that he has found the shells at Ibiza.

I think about to put some more rounder tuberculata in my database as form
lamellosa but is it correct? I wanted to buy a lamellosa from a trader
as a nice addition to my collection and to show the difference - but as
i looked as the picture to the shell its looking again like a taberculata
form... Anyone has sorted this out and had found the same problems?
