I found this Perrotet's Skink, Trachylepis perroteti whilst out for a walk the other day in Mali.
Pics aren't the best as the light was low and my camera kpet wanting to focus on other things. I'm looking for some more for better images.
They are fairly large skinks and quite attractively coloured. This is the first of two I have seen, the other was dead and very dried out.
