 Francisco Bay; occasionally southward in winter to central Mexico 

 (Valley of Mexico). 



[The type specimen of Ammodramus sand lo Id tens is hrunnescens 

 Butler agrees minutely with examples of this form from the coast 

 of California. There is no yellow ^yhatever in the superciliary stripe; 

 but this character is more or less variable in all the forms of this 

 species, and some Californian specimens of the present form are 

 equally destitute of yellow^ on the superciliar}- or supraloral region. 



An adult female from Tlalpam, Mexico (No. 143780, U. S. Nat. Mus., 

 Dec. 8, 1892, E. W. Nelson) is closely similar to Mr. Butler's type of 

 A. s. hrunnescens, and practically indistinguishable from some Califor- 

 nian examples.]
