BLUE TONGUE SKINKS

I was wondering if anyone knew what he was based off of his colorations, i got him off of craigslist and the lady didn't say what kind he was i thought he might have been an Merauke but looking at some pictures i dong know. Can anyone help me out Thank you

Also his name is Charlie

Yes, Merauke.

It does look like a Merauke, but better pictures, from over the top, side,and belly will help us identify it even better.
