Thanks for sharing the pics. It looks like it could be a caspian cobra. There is a wikipedia page for a caspian and if you click on the picture on that page under the word Description so it is expanded, the head looks identicle to your picture. Also reading through the dscription of markings given, it seems like a pretty good match.

When I went to the repticon here in Atlanta last month, there was a table who had about 10 adult camel spiders. Man those are the nastiest looking creatures. I mean, even if I didn't hate spiders already, those are enough to make me scream like a little girl.
