Terry - Yes, I am volunteering!

Damn. So close with the illustration, but just missed the mark. Ok, now that you have explained the interorbital bar. (but isn't 'inter' - inside? so inside the eye?) It has always looked to me, that adspersus has a very individual iris. Is there a name for that type of adspersus eye?

John .... I hoped that that was an adult edulis. After all the pictures I have been looking at, I really had hoped. Shoot!!! Now that you say that.... I think I understand. I can try again.

IMHO(with what little I know) adspersus is kind of unique, but edulis and obbianus should look similar? The physical descriptions only work on the adults, not the babies or juveniles? We really need to lock down pictures of the 'original' described species? But on all counts ..... count me in. I can work on more graphics as needed.
