New species - Slow Worm

I have seen probable evidence of slow worms before - round holes in compost heaps - but I saw one live for the first time a couple of days ago. I lifted up a large bird bath to find one resting below. I hastily put the bird bath back and got my camera hoping that the lizard would kindly remain in place. Alas it merely left me a wriggling tail and had slunk off to grow a new one.
