Disiribution. — This large lizard has been recorded from 

 Nebraska, Kansas, Colorado, New Mexico, Utah, Arizona, 

 Texas and northern Mexico. 



The Utah record seems to be based upon a single speci- 

 men collected by Dr. H. C. Yarrow and labeled merely 

 Utah. This record may be considered open to question until 

 confirmed. 



In Arizona, the species has been taken at Ash Creek, 

 Tucson, Prescott, Fort Grant, and in Carr Canyon in the 

 Huachuca Mountains.
