Vol. IV] VAN DENBURGH AND SLEVIN—ISLAND REPTILES ^49 



LAS TRES MARIAS. 



We have no specimens from these islands. Stejneger, in 

 the North American Fauna, No. 14, 1899, pp. 63-71, records 

 16 species of land reptiles. One of these, Diplotropis diplo- 

 tropis (Giinther), is known only from specimens labeled 

 merely the Tres Marias. The other species have been taken
