Sorry Richard,

I am not up on the snakes as well as can be said for the turtles.

I did however see a reference that stated that Cannia was described by Gray 1842, with a full citation so I assumed that was correct. However, if you described it and it is valid and no-one has sunk it, then it is valid and should be used.

As for A rugosus, if you resurrected it and no one has since refuted that, again it is valid.

ahh nomenclature.... makes you go grey early doesn't it...

Cheers, Scott
