We found this little snake curled up on our steps a few weeks ago, just taking a nap in the sun. After consulting the reptile and amphibian book, we determined this is an Andean Snail Eater (Dispsas andiana); a snake specialized in eating gastropods by tracking their slime trails. The snake has a distinctive U shape on its head that makes it easy to identify. The next day the Snail Eater had slithered off,perhaps in pursuit of snails.
