Help identify lizard and snake on Cozumel Island Mexico (1 Viewer)

My family and I went to Mexico during the 2nd week of Feburary. My dad and I spent a day on Cozumel Island looking for endemic bird species and while we were there we saw this lizard and snake. The lizard was about 9 inches including tail and the snake was about 6-7 feet long any help would be great in identifying these

Well, based on what I could see on this snake picture, it's a slender snake that has a tail that is around 1/4 of whole body length. Looks like it has a a pattern on the head? Also looks like it has keeled belly scales (if I saw correctly), which indicates that it's a good climber.
Now, I'm not an expert on Mexican snakes, but I love a snake ID challenge! I might be able to find what species it is, but I need a better picture (of the head at least) if you have it...
I'll try to find something on the internet, I'll let you know when I do...

On the lizard, I can't help you with that.

They both look very cute, though...

The lizard is a Cozumel Island Whiptail (Aspidocelis cozumela) which is endemic to the island. Can't be sure about the snake though. It looks like it could be some type of Racer, but I can't tell from that photo.

OK I wasn't able to find anything myself, but if you don't mind, I can ask people on a herp forum that I'm a member of, most of them are from North America, so maybe they can help...?
