Uta concinna was based on sixteen specimens collected on Cedros 

 Island by the Albatross Expedition. Three specimens from Natividad 

 Island, between Cedros and the mainland, in the U. S. National Museum, 

 have also been examined. 



The dorsal scales from a point opposite the posterior surface of the 

 thigh to the occipital average 92 in eight male specimens, ranging from 

 85 to 97. The difference from Uta stansburiana hesperis is slight, though 

 the dorsal scales are slightly larger and slightly smoother and the pos- 

 terior femorals are more weakly keeled in concinna. The two latter char- 

 acters distinguish it also from stejnegeri.

 Range. — San Pedro Martir Island, Gulf of California. 



Uta stellata Van Denburgh

 p. 52. 

 Range. — San Benito Islands, off the Pacific coast of Lower California. 



The Albatross Expedition collected seven specimens (A. M. N. H. 

 Nos. 5414-5418, 5420, U. S. N. M. No. 64486) on East and West San 

 Benito. These agree excellently with the original description of Van 

 Denburgh. The dorsal scales from the occipital to rump number from 

 110 to 125 in the specimens examined. The femoral pores in the large 

 series recorded by Van Denburgh and Slevin (loc. cit.) average 15. 



Uta squamata Dickerson 



Uta squamata Dickerson, 1919, p. 47 1. 1 



Range. — Santa Catalina Island, Gulf of California. 



The series of six specimens collected by the Albatross Expedition, 

 on which this species is based, is excellently preserved. The species is a 

 very distinct one, though directly allied to Uta elegans of the peninsula. 

 The dorsal scales from the occipital to the base of the tail range from 70 

 to 78. The length of the hind leg divided by that of the body averages 

 .79, in which respect squamata is the only species of the stansburiana 

 group approaching elegans.
