Thanks everyone, I appreciate it. I did contact him about a picture of the dead lizard, but he said that wont be necessary, and that he will contact me as soon as the next order arrives. But the lizard will remain in the freezer until then.

Too many bad experiences to just chuck away the evidence, lol.
The species is
Calotes Bachae, a recently discovered species as of January 2013 - until then it was thought to be
Calotes mystaceus, a similar looking species, but not the same. This is the second time that I've seen then up on the market (not that I don't expect to see a lot more in the future), so I figured I would have a go at it, and try for a future breeding pair...well at least I've got a female out of it.
I'll keep you guys updated if he does send a new male, and hopefully I'll have some nicer pictures of a healthy lizard! Beautiful species, just wish it would have gone smoother than this.
I do plan on revealing where I got the two from, just want to wait until the next order with the male though so he can at least have a little more dignity (hopefully) than he had with this first order. This is a new distributor to me, and therefore I have never ordered from here before.
