I think our Ugandan guide was first really sure he had a lunatic on his hands when I made him back up the jeep so I could take a picture of this lizard on a tree trunk near the road. It wasn't a particularly large or beautiful or probably even rare lizard, but it was one I hadn't seen.

This skink picture went unidentified for a year and a half. Dr. Robert Drewes told me it was definitely a skink, probably a Mabuya, but he couldn't tell which species. Now with the new field guide to East African reptiles (of which Dr. Drewes is a coauthor), I could make an educated guess. Based on the descriptions and ranges provided in that book, I believe this to be Mabuya maculilabris, though I'm not completely sure.
