Remarks. — In Mexican specimens the femoral pores 

 are said to vary from 13 to 20, the dorsals equal to shielded 

 part of head from six to 1 0, and the dorsals in a row from 

 interparietal to base of tail from 33 to 48 (Boulenger). 



Distribution. — This small lizard is widely distributed in 

 Mexico and crosses the boundary of the United States into 

 southeastern Arizona. Texan records are erroneous, being 

 based upon specimens of 5. variabilis. Arizona records are 

 very few. Baird recorded a specimen taken near Los No- 

 gales. I examined specimens collected by William Price 

 in the Huachuca Mountains ("near the summit" and "at an 

 altitude of 9,500 feet.") and in Morse's Canyon, near Fair- 

 bank, Cochise County. Mr. Slevin recently has collected a 

 few specimens in the Huachuca Mountains, Cochise County, 

 at an altitude of about 9,500 feet on Miller Peak, at 8,000 

 feet at the head of Ash Canyon, and at 8,000 feet near the 

 head of Ramsey Canyon. He also secured one at about 

 9,000 feet altitude on Old Baldy, in the Santa Rita Moun- 

 tains, Santa Cruz County. 



Habits. — Mr. Slevin found this lizard only at the 

 higher levels of the mountains above seven or eight thous- 

 and feet. The first specimens he collected were found 

 about 300 feet below the summit of Miller Peak, in a small 

 open grassy area on the western slope. Here the grass grew
