Lución

thanx people, i thought it was a snake.

I would say it's a Male Slow Worm - Anguis Fragilis

Yes, I thought slow worm as well.

This is a legless lizard. There are a couple species in Spain.
This website seems to have a lot of photos (it might help you with the other lizard you posted as well): http://www.euroherp.com/species

Possibly a Slow Worm, Anguis fragilis: http://en.wikipedia.org/wiki/Anguis_frag...
