Not that I don’t believe you, but did you see the organ yourself or did you read it in a scientific article?[/quote]
Bartian, I saw the labyrinth once at a large dead male (true) deissneri that was dissected. It was confirmed by Walter Foersch to me personally who had no deissneri but tweediei-like forms. But: Alas! no, I had no motive to write an article about that since it was not doubted that Paros have labyrinths. I read that opinion here for the first time. The burden of proof is with Anton, I think!
