SOUTH FARALLON ISLAND. 



Only one kind of salamander is known. 

 1. Autodax lugubris farallonensis Van Denburgh. 



Five specimens collected June 15-July 1, 1911, by E. W, 

 Gifford, are Nos. 27335 to 27339. 



AND NUEVO ISLAND. 



This island was visited by Mr. R. H. Beck, July 1, 1909. 

 He collected the following lizard: 

 1. Gerrhonotus caeruleus Wiegmann. 



Eight typical specimens (Nos. 14520 to 14527) were se- 

 cured. These show dark lines between the rows of ventral 

 scales. The dorsal scales are in 16 rows in six specimens, but 

 there are only 14 in Nos. 14520 and 14526. 



SAN MIGUEL ISLAND. 



One salamander and two lizards are known from this 

 island. We visited San Miguel in April, 1913, but the weather 

 was not favorable for collecting. 



1. Batrachoseps pacificus Cope. 



Two specimens (Nos. 36083 and 36084) were found under 

 a piece of a fallen fence post in a little gully, April 11, 1913. 

 The costal grooves in these specimens are 18 in number. One 

 of these salamanders had a reddish dorsal band similar to that 

 seen in some specimens of Batrachoseps attenuatus and Pletho- 

 don cinereus. The other showed the uniform yellowish brown 

 coloration characteristic of all other known specimens of 

 B. pacificus. 



2. Sceloporus becki Van Denburgh. 



We failed to find this lizard on San Miguel Island. The 

 Academy collection contains only the type specimen (No. 

 4537) collected on San Miguel, by R. H. Beck, March 26, 

 1903. 



3. Gerrhonotus scincicauda Skilton. 



The only specimen collected by us on San Miguel (No. 

 36082) was found under a stone April 11, 1913. Its dorsal 

 scales are in 14 rows. The temporal scales and those on the 

 arm and forearm are smooth. The dark ventral lines run 

 along the middles of the scale rows.
