NOTES ON A COLLECTION OF REPTILES FROM 
SOUTHERN CALIFORNIA AND 
ARIZONA 
BY JOHN VAN DENBURGH 
Curator of the Department of Herpetology 
Through the kindness of my friend Dr. Charles H. Gilbert 
I have been afforded an opportunity to examine and report 
upon a collection of reptiles brought together by Mr. Dane 
Coolidge in 1897 and 1899. The material is chiefly of interest 
as an aid toward a more complete knowledge of the distribu- 
tion and variation of a number of Californian species. It 
contains no forms new to science. The specimens, several 
hundred in number, were secured at various localities in San 
Bernardino, Riverside and San Diego counties, California, 
and near Yuma, Arizona. They are the property of Leland 
Stanford Junior University and form a part of its zoological 
collections.
