it was the juvenile coloration on such a large individual that confused me the most despite being outside of the currently known variegatus range. unfortunately we had no standard means of measuring the gecko at the time though I believe somebody else got some pictures of it next to a reference item.

Next week I'm getting a metric ruler to the millimeter tattooed on my forearm so I can never say I didn't have a ruler for anything under 20cm. This was my first trip to Texas but I do a bit of herp survey work in the northeast and it's painful how many times I find something when I'm not expecting it and don't have a ruler on hand.

I also figured out why I couldn't find any info on the Tucson -- I was spelling it "tuscan"

thanks.
