Our only specimens of this lizard were destroyed in the 

 great San Francisco fire of April, 1906. I now know the 

 species only from the original description, which is as 

 follows: 



Description. — "Body with irregular dorsal and lateral 

 black markings limbs with transverse black bars on outer sur- 

 faces. Four dorsal ridges, consisting of single, strongly 

 carinate scales, the middle pair separated by an irregular 

 series of smaller simple scales. There is a shorter pair of 

 dorso-lateral ridges of carinate scales, somewhat less regu- 

 lar. Tail more than twice the head and body; otherwise 

 similar in size and proportions to U. symmetrica. Colors 

 bluish, similar to IJ . auriculata from Socorro Island. Adult; 

 under parts much lighter blue than upper; young, dusky 

 above, whitish below." 



Distribution. — This lizard is known only from Clarion 

 Island, Revilla Gigedo Islands, Mexico, where it has been 

 collected by Townsend, Anthony and Beck.
