Pittcopkis vertebralis was originally described from a 

 specimen which Botta collected in " California." Mr. 

 Xantus found it at Cape San Lucas, and Mr. Belding at 

 La Paz.

Tropidonotus orclinatus var. eques. 



(1893, Boulenger, Cat. Snakes Brit. Mus., i, p. 209.) 



Since Mr. Xantus secured a single garter snake at Cape 

 San Lucas, no representative of this genus has been re- 

 corded from Lower California. It seems hardly probable 

 that the Lower Calif ornian form is identical with that of 

 the Mexican mainland.
