I was kinda hesitant to call them gilbirti from this locale at first, I'm far from a herpitologist,that is for sure. But what had me convinced was the first two skinks found in the lower elevation, with the pinkish/orange tails were all alot smaller than the "for sure" Skiltons found up h...

The type locality for Plestiodon gilberti cancellosus is in Alameda Co., and if you're finding these skinks where I think you a...

Mis-ID's or not, C. longicaudae needs to be an option. It is a valid taxon of California's herp diversity.

Some people are still entering California populations of Phrynosoma blainvillii as P. coronatum. As taxonomy changes it's simply a difficult thing to get everyone on the same page.
