other kinds, including GerrJwnotiis and Hypsiglena, occur on 

 these islands^ 



1. Crotalus oregonus Holbrook.

Streets recorded as Crotalus adamanteus atrox a rattlesnake 

 which he secured on Los Coronados. Dr. Stejneger has 

 shown that this specimen, which is still in the National 

 Museum, is a Pacific Rattlesnake. 



San Martin Island. 



The only reptile heretofore known from San Martin is a 

 gopher snake found by Dr. Streets. The Academy has also 

 specimens of two species of lizards from the island, both of 

 which are here described as new. The Uta probably is con- 

 fined to the island, while the Gerrhonotus seems to be found 

 throughout the San Diegan Fauna.
