The one on the left is an agame-species ( not sure which species ), the one ont the right is a Cordylus-species ( also not sure which species ).
I believe the one on the left is a Mwanza Flat-Headed Rock Agama (Agama mwanzae). No idea on the one on the right but as I saw it, too, I'm also interested in what it could be. ~Thylo
The cordylus is Cordylus tropidosternum or jonesii. Its hard to tell unless you can get a good view of the head.
