TRANSACTIONS OF THE SAN DIEGO SOCIETY OF NATURAL HISTORY Volume XI, No. 2, pp. 41-48, plate 3. August 26, 1946 A NEW GOPHER SNAKE (PITUOPHIS) SANTA CRUZ ISLAND, CALIFORNIA Laurence M. Klauber of Reptile! and Amphibians, San Diego Society of Natural History In a recent study of the gopher snakes of the genus Pituophis in Baja CaUfomia,* it was found that three island populations differed sufficiently from those of the mainland to warrant recognition as new subspecies. This naturally led to an investigation of the snakes found on the islands off the coast of the State of California, Pituophis being definitely known to occur on two, Santa Cruz and Santa Catalina, and rumored on a third, San Clemente. I have been unable to find any important differences between the Santa Catalina specimens and Pituo-phis catenifer annectens of the nearby mainland; but the Santa Cruz Island snakes, while overlapping, in some degree, both P. catenifer catenifer and P. c. annectens, possess average differences which warrant nomenclatorial segregation.
