Vol. IV] VAN DENBURGH AND SLEVIN— ISLAND REPTILES ^37 



SAN NICOLAS ISLAND. 



Mr. Slevin spent five days on San Nicolas Island, Novem- 

 ber 7-11, 1911. He found only the single species of lizard 

 known from this island. 



1. Xantusia riversiana Cope. 



One hundred and twelve specimens (Nos. 30754 to 30864 

 and 35793) were secured. These are of various sizes, and 

 show a wide range of coloration. They were found under 

 flat stones just above the high tide line on the beaches. They 

 are very active when disturbed. Careful comparison with 

 our series from San Clemente and Santa Barbara islands has 

 not disclosed any differences. 



SANTA BARBARA ISLAND. 



This island was visited by Mr. Slevin, October 4, 1912, and 

 a few hours collecting resulted in finding only the one known 

 species. 



1. Xantusia riversiana Cope. 



Twenty-one specimens (Nos. 35567 to 35587) were col- 

 lected. They were found under rocks near the north end of 

 the island. They seem identical with the specimens from San 

 Nicolas and San Clemente islands. 



SANTA CATALINA ISLAND. 



One salamander, two lizards and a rattlesnake have been 

 reported from Santa Catalina Island. We now are able to add 

 a Hyla, a snake and two other species of lizards. 



1. Batrachoseps attenuatus (Eschscholtz). 



The salamanders of Catalina seem not to differ from those 

 of the mainland. 



2. Hyla regilla Baird & Girard. 



Seventy-six specimens (Nos. 26898 to 26973) were collected 

 near Avalon, July 23 to September 8, 1910, by John I. Carlson, 

 and Mr. Slevin secured 17 (Nos. 35550 to 35566) at the 

 isthmus of the island, September 29 and 30, 1912.
