To me it seems a little odd, from the photo's shown, I'm am not keen to say it's 100% vitticeps, looks slightly intergradish...or hybrid.. the spine configuration on the head seem to look Central, though it's head shape seems a fraction to long for it's width, but it's the enlarged scales around the base of the tail that seem to look a bit barbata, Just out of interests sake, what is the colour of it's gums?
