Vol. IV] VAN DENBURGH AND SLEVIN— ISLAND REPTILES ^39 



are now able to record a second specimen. This is No. 4323 

 in the collection of the Museum of Vertebrate Zoology, Uni- 

 versity of California, and was found by Mr. Camp at an 

 elevation of about 25 feet near the isthmus of the island, July 

 7, 1910. It is a male with scales in 23 rows, gastrosteges 169, 

 urosteges 23, supralabials 15-15, infralabials 14-14, preoculars 

 2-2, and postoculars 3-3. 



SAN CLEMENTE ISLAND. 



Mr. Slevin collected on San Clemente Island three days in 

 October, 1912. He secured only the two kinds of lizards 

 previously known from this island. 



1. Uta stansburiana Baird & Girard. 



Eighty-three specimens (Nos. 35710 to 35792) were se- 

 cured. They seem not to differ from mainland lizards of this 

 species. 



2. Xantusia riversiana Cope. 



One hundred and twenty-two of these lizards were collected 

 on San Clemente Island by Mr. Slevin October 15 to 17, 1912. 

 They were taken in the vicinity of Mosquito Harbor, and were 

 found under stones near the beach and on the plateau several 

 hundred feet above. There appears to be no difference between 

 these lizards and the Xantusias of San Nicolas and Santa 

 Barbara islands. 



LOS CORONADOS. 



Mr. R. H. Beck visited these islands in 1908J and collected 

 several species not previously recorded. 



1. Batrachoseps attenuatus (Eschscholtz). 



Fifty-five (Nos. 13477 to 13531) were collected on East 

 Coronado Island, February 15, 1908, and five (Nos. 13604 to 

 13608) are labeled merely Coronado Islands. They seem iden- 

 tical with specimens from the mainland. Costal grooves in 38 

 specimens are 18 on each side except in specimens Nos. 13509 

 and 13512, which have 19. 



2. Autodax lugubris (Hallowell). 



Two specimens (Nos. 13609 and 13610) labeled Coronado 

 Islands were collected February 22, 1908. Their costal grooves 

 are 12 on each side.
