3. Uta stansburiana Baird & Girard. 



One hundred and sixty-six specimens are before us. Eighty- 

 four of these (Nos. 26812 to 26895) are from the vicinity of 

 Avalon, July 23 to August 26, 1910, while 82 (Nos. 35468 to 

 35549) were secured near Johnson's Landing, at the north 

 end of the island, September 29 and 30, 1912. Femoral pores 

 in 34 specimens vary from 12 to 16; being 12 ten times, 13 

 eighteen times, 14 nineteen times, 15 eighteen times, and 16 

 three times. 



4. Xantusia riversiana Cope. 



Although Mr. Rivers stated that he had received this species 

 from Catalina Island it is very doubtful if it really occurs there. 

 Extended search by Mr. Carlson revealed no specimens, nor 

 was Mr. Slevin more successful in finding it on this island, 

 and no other collector has secured it there. 



5. Gerrhonotus scincicauda ignavus Van Denburgh. 



A single specimen (No. 26896) was collected at Avalon, 

 August 13, 1910. There are 14 longitudinal rows of dorsal 

 scales, and the dark lines on the belly run along the middles 

 of the scales. Owing to the fact that this specimen is quite 

 young, the temporals are not keeled, but the caudal keeling 

 is typical of this subspecies. 



6. Eumeces skiltonianus (Baird & Girard). 



A single young individual (C. A. S. No. 26897) taken by 

 Mr. Carlson at Avalon, August 1, 1910, establishes the first 

 record of this species on Catalina Island. 



7. Pituophis catenifer (Blainville). 



Mr. Charles L. Camp has informed us that he found a good- 

 sized gopher snake at the isthmus of the island, July 3, 1910, 

 but that it escaped. We know of no specimen from Catalina 

 in any museum. 



8. Crotalus oregonus Holbrook. 



The presence of rattlesnakes on Catalina was first recorded 

 by Yarrow from a specimen taken there by Mr. Schumacher 

 in 1876. This record has remained unconfirmed. Through 

 the kindness of Dr. Grinnell and Mr. Charles L. Camp we
