Notes

A population of U. ornatus seems to be very well established on my property as well as the rest of our block. I am unsure as to how widespread they are here but this population has been here for at least 10-15 years. Every year I see more and more YoY's adding to my belief that they are well established.

Jonathan, no this is not the same population you are speaking of. Jim Bass and I have discussed this posted population on the past and though we did not positively ID them, I have personally observed the dorsal scalation and found that the outter rows of scales are much larger than the ones closer to the spine. What exactly that entails, I do not know. I will change the double post.

p.s. - I just noticed that this is a double entry.

Is this from the city of San Bernardino? If it's the population Jim Bass and I surveyed, then the best guess of the several people who have looked at them is that it's Urosaurus ornatus symmetricus, though it's admittedly difficult to ID introduced subspecies. The best ID characteristic is the width of the small scales going down the middle of the back. Plus, U. o. symmetricus seems a much more likely candidate for introduction here (though you might know something I don't know).
