The smaller one is the lesser x mojave, and the larger is the pure lesser. I could not get the greatest pic because they would not hold still, but you can still see the color is the same. Neither or them are true pure white IMO but if you see them right after a fresh shed they are pretty close. IMO The only way to get a true bright white snake is with a lesser pied. That is a WHITE snake.
