SAN BENEDICTO ISLAND. 



Mr. Slevin spent several hours on this island, July 26, 1905, 

 with four other members of the expedition. No reptiles were 

 seen by any member of the party, although careful search was 



SOCORRO ISLAND. 



1. Uta auriculata Cope. 



This Uta remains the only reptile known from Socorro Is- 

 land, except the green turtle which breeds here in numbers. 

 Ninety-two specimens (Nos. 8933 to 9024) collected by Mr. 

 Slevin, July 27-28, 1905, are now before us. In life their 

 bright blue coloration makes them conspicuous on the black 

 lava. The femoral pores are small and difficult to count. In 

 20 specimens they vary in number from 10 to 13; being 10 

 eight times, 11 eighteen time, 12 eleven times, and 13 three 

 times. 



CLARION ISLAND. 



We now have no specimens from this island, the great fire 

 of 1906 having destroyed those we had. The two species 

 known from Clarion are a lizard and a snake : 



1. Uta clarionensis Townsend. 



2. Bascanion anthonyi Stejneger. 



ANGEL DE LA GUARDIA ISLAND. 



Three species of reptiles have been recorded from this 

 island.

Townsend has recorded the presence of this lizard on Angel 

 Island, Gulf of California. 



2. Sauromalus hispidus Stejneger. 



Sauromdus ater, Streets, Bull. U. S. Nat. Mus., No. 7, 1877, p. 36; 

 Townsend, Proc. U. S. Nat. Mus., XIII, 1890, p. 144. 



Sauromalus hispidus Stejneger, Proc. U. S. Nat. Mus., XIV, 1891, 

 p. 409. 



Dr. Stej neger has described this species from four specimens 

 collected by Dr. Streets and Mr. Townsend on Angel Island. 

 Dr. Streets states that these lizards are abundant on the island.
