My what big eyes you have, Lyriocephalus!

Looking like some sort of medieval fever dream,
meet Lyriocephalus, the hump-nosed lizard (Fig. 1), a cousin to Draco, the gliding lizard. Distinct from Draco, the body of this insectivore is laterally compressed, not laterally extended.

Probably the largest eyes
relative to the skull of any tetrapod. Lyriocephalus, is an arboreal jungle lizard with an anterodorsal naris and a small antorbital fenestra. Note the arching postorbital contacting the prefrontal.

Lyriocephalus scutatus (Merrem 1820) is represented by a skeleton at Morphospace.org where you can rotate the skeleton on your monitor. Note the brevity of the tail of this agamid iguanid, There are more in vivo pix here. And a video here.
