A NEW RACE OF THE CALIFORNIAN THRASHER 
FROM LOWER CALIFORNIA. 
BY JOHN E. THAYER AND OUTRAM BANGS. 
In the autumn of 1906 Mr. W. W. Brown, Jr., made a large 
collection of birds, for the Thayer Museum at Lancaster, Mass- 
achusetts, in the vicinity of San Quintin, Lower California. At 
Rosario he took a fine series of the Californian Thrasher, that 
represents a subspecies easily distinguished from true Toxostoma 
rediviva or T. rediviva pasadenensis, which we propose to call 
Toxostoma rediviva helva subsp. nov. 
Type, from Rosario, Lower California (latitude 30°), adult 9, no. 6000, 
coll. of John E. Thayer, Lancaster, Massachusetts, collected Nov. 19, 
1906, by W. W. Brown, Jr. 
Characters.— Similar in size and proportions to true T. rediviva; colors 
all much paler than in true 7. rediviva or T. rediviva pasadenensis — 
back grayer, less brownish; pectoral collar much paler, less strongly
