ZooL.— Vol. IV] VAN DENBURGH— COAST ISLAND REPTILES 1 5 



Dr. Loew on Santa Cruz Island ; that is to say, they approach 

 in this respect the Ula of San Benito Island. The dorsal 

 scales, however, are well keeled and the caudals are of the 

 normal type. The femoral pores in the Ana Capa specimens 

 are 14-14, i4-i5' H"?' i4-i5' 14-H' i4-i5' ^^d 14-15. 



San Nicolas Island. 



San Nicolas Island is the type locality of XanUisia rivers- 

 iana. No other reptile has been found there.

 this XanUisia taken by himself on San Nicolas Island, May 

 22-23, 1897. One of these specimens is uniform drab, with 

 a few dark spots. The others are of the handsome striped 

 style of coloration (see plate). 



Santa Barbara Island. 



I believe no reptiles or amphibians have been recorded

1. Xantusia riversiana Cope. 



Mr. Joseph Grinnell has sent me four Xantusias from 

 Santa Barbara Island. They are smaller than the speci-
