Cryptoblepharus carnabyi is a small, widespread, variable skink species that is probably a complex of insufficiently studied interrelated species. It's also extremely similar in general appearance to Cryptoblepharus plagiocephalus, with the most tell-tale differences being the number of scales on the upper lip, and the scale pattern of its tiny little palms. I'm guessing that this individual is C. carnabyi based mainly on the fact that it was found on a rock at riverside. This is typical habitat for C. carnabyi, whereas C. plagiocephalus is mostly found on trees, walls, fences, and such.
