verging toward Passerculus rostrahis rostratus, constitute the 

 first record of this subspecies for California; and Mr. Brown 

 has already announced this discovery.* 



The present subspecies breeds commonly on the San Benito 

 Islands, where Mr. H. B. Kaeding found fresh eggs as early as 

 March 27-30, 1897. f 



The migration of Passerculus rostratus guttatus proves to 

 be nearly as astonishing as that of Passerculus rostratus rostratus. 

 In this case, however, the line of travel is, so far as known, 

 only northw^est and southeast along the coast for about the 

 same distance in each direction from the breeding area, the 

 linear extent of the winter range being about 900 miles. This 

 subspecies is apparently confined to the immediate coast, and 

 in Lower California also to the Pacific Coast, except in the Cape 

 San Lucas region, where it occurs along the Gulf of California 

 as well; but there is no interior record for either Lower Cali- 

 fornia or California. 



We have examined 125 examples of this species, from the 

 localities given below.

 Anaheim Landing, Orange County (Oct. 5, 1916); Alamitos 

 Bay (Sept. 9, 1913) ; San Pedro, Los Angeles County (Oct. 

 30, 1901).
