1922] Schmidt, Amphibians and Reptiles of Loicer California 623 



The fauna of the island of Angel de la Guardia consists of the fol- 

 lowing seven forms : 



*Saurotnalits hispidus ^Cnemidophorus dickersonse (Isla Partida) 



*Crolaphi/tus insularis *Crotalus alrox elegans 



*Callisaurus splendidus Crotalus mitchellii 

 Uta stansburiana stejnegeri 



Of these, the five starred are peculiar to the island. As far as our present 

 knowledge of these species goes, they are equally related to Lower Cali- 

 fornian and West Mexican representatives. 



From Sal Si Puedes Island, only one species, Cnemidophorus canus, 

 is known. 



A single species, Crotalus tortugensis, is known from the island of 

 Tortuga. 



From San Marcos Island, only Verticaria hyperythra schmidti is 

 known, a form widely distributed on the peninsula. 



Five species are known from Carmen Island: 



Callisaurus ventralis gabbii *Verticaria cserulea 



Uta elegans * Cnemidophoras vandenburghi 



Uta microscutata 



Of these, the two last are peculiar to the island; the other three are found 

 on the adjacent shores of the peninsula. Verticaria cserulea is interesting 

 as an insular representative of the more plastic peninsular form, Verti- 

 caria hyperythra schmidti. 



From Monserrate Island, only two species, Sceloporus monserratensis 

 and Verticaria picta, are known. 



Five species are known from Santa Catalina Island : 



Dipso-saurus dorsalis lucasensis * Cnemidophoras catalinensis 



*Sceloporus lineatulus *Lampropeltis catalinensis 



*Uta squamata 



The peculiar species of Sceloporus differs very slightly from the mainland 

 form, while the Uta, Cnemidophorus, and Lampropeltis are much more 

 distinct from their peninsular allies. 



Only a single highly peculiar species, Sator angustus, is known from 

 Santa Cruz Island. 



Six species are now known from San Jose Island : 



Callisaurus ventralis gabbii Uta microscutata 



Sceloporus zosteroynus * 'Cnemidophorus celeripes 



Uta elegans *Verticaria sericea
