Warning: Another lizardy-thing

This jumped out in front of me yesterday - nearly giving me a heart attack. I thought in that first second it was a snake. I'm not scared of snakes as a species but it strikes me as jolly sensible to avoid something that's poisonous or liable to squeeze me to death. Anyway, once I'd established it was marginally more scared of me than I was of it... I took some photos.

Since I haven't bought my reference book yet, Boonsong can you help identify this one please?

I spent the rest of the day jumping at leaves brushing my shoulders and frogs smaller than my thumbnail jumping in the dark. What a wuss.
