one specimen I am able to trace the pattern of five primary crossbars 

 (three black and two dusky), with four secondary bars on the inter- 

 spaces. In other specimens, only the anterior secondary bars are evi- 

 dent, making seven crossbands, as in the type of U. repens. The length 

 of the hind leg, when compared with that of the body from snout to anus, 

 varies from .58 to .73 (ten specimens). In the type of repens, the ratio 

 is .60, and in one of the specimens of thalassina, whose measurements are 

 given by Van Denburgh, it is likewise .60. The length of the head in 

 repens is .31 of that of the body, .23-. 27 in the available thalassinas. 

 In view of these facts, I do not think that U. repens can be maintained.

Specimens in the Biological Survey collection come from La Provi- 

 dencia Canon, east base of San Pedro Martir Mts., (U. S. N. M. Nos. 

 37627-8). 



The specimen (Acad. Nat. Sci. Phila., No. 12644, Cope collection) 

 recorded by Lockington as U. thalassina is a typical Uta mearnsi. It is 

 interesting that a specimen of so distinct a species should have passed 

 through Cope's hands and remained undescribed. 



In two specimens of this species with a reproduced tail (in the col- 

 lection of the Field Museum) the tail is as long as, or slightly longer than, 

 the normal tail.

A specimen in the National Museum (U. S. N. M. No. 37689), from 

 Volcano Lake, northeastern Lower California, is a typical stejnegeri. 

 A single immature specimen in the Albatross collection (U. S N. M. No. 

 64487), from Angel de la Guardia Island, where a distinct form might be 

 expected, resembles stejnegeri in scales and leg length. It is probable
