Doug, GUEST - in my post of 04:33 AM, which preceded both of yours, I acknowledged my own brain fart, and agreed that the Adder is not the same thing as the Grass Snake!

Not much point in continuing to point out an error that's already been noted and acknowledged, surely?

What I meant to say originally, of course, was 'Adder (a.k.a. Viper)...".
