Thank you all for your reply's.

That is why I asked, I got the second one a month ago and it was sold to me as a Mojave, as soon as I saw her I thought that there were something diferent in her because she didn't look like the one I all ready have.

I'm not an expert ID'ing snakes so I thought it could be a poor example of a mojave or something different.

What are the visual marks that ID the Butters or Lessers from Mojaves?
