Remarks. — This lizard is smaller than^. o. biseriatus and 

 larger than S. consobrinus. The dorsal scales average smaller 

 than in either of these species. It agrees with ^. consobrinus 

 m having two blue patches on the throat, while males of 

 S. o. biseriatus have only one. Some specimens from south- 

 ern Utah seem to be almost indistinguishable from 5. con- 

 sobrinus. 



Distribmion. — This species was found originally on the 

 Painted Desert of Arizona, where it was secured at Moa 

 Ave and on the Little Colorado River, in Coconino County. 

 More recently, it has been collected in Colorado and Utah. 

 In Utah, it has been secured in Grand (Thompson), Mil- 

 lard (four miles north from Scipio, seven miles south from 

 Kanosh), Iron (four miles and twenty miles north from 

 Parowan), and Washington (Zion National Park, Spring- 

 dale, between Rockville and Springdale), counties. 



Habits. — This species was found on large boulders and 

 cliffs in a canyon at Thompson. It was not observed on 

 the ground between the boulders.
