Vol. IV] VAN DEN BURGH AND SLEVIN— ISLAND REPTILES 3^43 



GUADALUPE ISLAND. 



No reptiles or amphibians have been collected on Guadalupe 

 Island. The only information we have been able to secure 

 as to their occurrence on this island is contained in a paper 

 by Edward L. Greene, published in Bulletin No. 4 of the Cali- 

 fornia Academy of Sciences, p. 220. He writes : 



"Of reptiles I met with only two or three small lizards. 

 In the moist parts of the plateau are plenty of shallow and 

 tepid pools, fed by springs, but not even a tadpole was visible ; 

 and both soldiers and seamen assured me that none of the 

 toad or frog race were ever seen or heard on Guadalupe. 

 Most other islands off the coast of Mexico are commonly re- 

 ported to be alive with snakes ; but no one charges this remoter 

 and more oceanic pile with harboring serpents of any sort; 

 and during my seven days of incessant rambling and climbing 

 I did not see one." 



SAN BENITO ISLANDS. 



There are three islands in this group — West, Middle and 

 East San Benito. Only one species of lizard has been taken 

 here. It occurs on all three islands. 



1. Uta stellata Van Denburgh. 



The type probably came from West San Benito Island. 

 We now have 100 specimens (Nos. 8718 to 8817) collected 

 on this island by Mr. Slevin, July 14, 1905; four (Nos. 8834 

 to 8837) taken on Middle San Benito, July 15, 1905; and 16 

 (Nos. 8818 to 8833) secured on East San Benito, July 15, 

 1905. Femoral pores in 50 specimens from West San Benito 

 vary from 12 to 18; being 12 once, 13 seven times, 14 twenty- 

 three times, 15 twenty-eight times, 16 eighteen times, 17 four 

 times, and 18 three times. In 12 specimens from East Benito 

 the femoral pores vary from 13 to 16; being 13 four times, 14 

 seven times, 15 nine times, 16 four times. In the four lizards 

 from Middle San Benito Island the pores are 15 five times and 

 16 three times. 



This small scaled member of the Uta stansburiana group is a 

 ground dwelling species. It was most abundant on the lower 

 portions of the islands.
