bluish J each plate on the side of the head above, each labial, 

 upper and lower, and each mental plate with a conspicuous, 

 rounded, bluish-white spot occupying all but the outer border. 

 The effect is that of three rows of spots on the side of head 

 and one on each side the chin. The middle lateral, or that 

 on the upper labials, is continued backward as a large spot 

 in front of the ear and another on its posterior edge running 

 out behind into a point. There are traces of similar spots 

 on the other cephalic plates, but much less distinct. 



"With advancing age the ground color becomes more 

 olivaceous, paler beneath, each upper scale with a posterior 

 margin of darker olive very well defined. These characters 

 continue until the specimen is 75 mm. long, head and body, 

 the spots on the chin only disappearing in the pale olivaceous 

 green of the under parts. The light line through the ear is 

 continued faintly to the foreleg."

Distribution. — This lizard has been stated to occur in 

 western Texas, Oklahoma, Kansas, New Mexico and Arizona. 



Arizona records are Gila River, Cave Springs and Fort 

 Whipple. 



I have received from the University of Michigan a 

 young P. guttulatus collected by Ed. Ratliff in Monte- 

 zuma Canyon, Huachuca Mountains, Cochise County, 

 Arizona, in the fall of 1919. 



Remarks. — It will be noted that this lizard has about the 

 same distribution as P. obsoletus. The young of the two 

 species are quite differently colored, those of P. obsoletus
