I've had a really hard time figuring out what the correct/accepted name for this species is. It appears to be a Cape Giant Whiptail (see http://www.californiaherps.com/noncal/baja/bajalizards/pages/a.maxima.html).
I think the name should be Aspidoscelis maxima (as on the above link)? Or is it Cnemidophorus maximus (perhaps an older synonym)? Or is it a subspecies of Aspidoscelis tigris, which is what the current taxonomy of iNaturalist sort of implies?
