That's an "extreme hypo" tangerine Honduran Milksnake. They display a great reduction in dark pigment(melanin), reduced so much so that there is ZERO black tipping on the scales, much thinner, reduced bands(vanished in some areas), deep "ruby-red" eyes, and an overall intensified neon pumpkin orange coloration.
Here is a pic of a normal "tangerine" phase Honduran, still a nice looking animal, but note all the black tipping on the scales, and a somewhat "dirtier" look, and wider jet black rings.

Here's a fairly recent pic of the same "extreme hypo" in my above post. He's an '06 male that I hope will breed this year.

another fairly recent pic of him taken a couple months ago.
