HERPETOLOGY OF LOWER CALIFORNIA. 



143 



viduals from Lower California differ from those collected 

 in California, in having the scales of the white rings 

 marked basally with black or dark brown. This black 

 edging seems to appear first upon those scales which are 

 nearest the median dorsal line, and to extend to the lateral 

 ones and over more and more of the surface of each 

 scale, as the animal increases in size. 



The type was taken by John Xantus near Cape San 

 Lucas. Mr. Belding found the species at La Paz.
