I.d. challenge!!

[Lee'scrazybeasts]

Hey up me ducks! I found a lonely T in a small tub labelled as a golden baboon. For a tenner I couldn't leave it so took it home. I've looked at all I can and believe it down to two types.... It's either a augacephalus ezendami or a pterinochilus chordatus... or not! Some help would be apreciated.
Many thanks
