that some of the specimens recorded by Meek, and here assigned to this 

 species on geographical grounds, may be intergrades between stejnegeri 

 and hesperis. Two specimens in the Academy of Natural Sciences of 

 Philadelphia, collected by S. N. Rhoads in the Cocopah Mountains, 

 northeastern Lower California, represent this form (A. N. S. P. Nos. 

 16102, 16106).

The Albatross collection contains six specimens from San Bartolome 

 Bay on which Uta parva is based. I am unable to find any characters 

 sufficient to distinguish this scries from hesperis. The length of hind leg, 

 given in the original description as 42 mm. (for the type), is in error for 

 32. A. M. N. H. No. 5431 measures 48 mm. from snout to anus, which 

 is not appreciably different from the average size of hesperis. The keeling 

 of the posterior femorals distinguishes it slightly from concinna. 



Uta martinensis Van Denburgh 



Uta martinensis Van Denburgh, 1905, p. 18, PI. vi; Stejneger and Barbour, 1917, 

 p. 50. 

 Range. — San Martin Island, off the Pacific coast of Lower California. 



The only characters which distinguish this species from Uta stans- 

 buriana hesperis are the considerably larger size and the slightly larger 

 scales. The type of martinensis measured 62 mm. from snout to anus, 

 while the maximum bod} r length recorded for hesperis by Richardson is 

 53 mm.
