PASSERCULUS SANDWICHENSIS BRYANTI Ridgway. 

 BRYANT'S MARSH SPARROW. 



Similar to JP. s. savanna, but smaller and darker, with more slender 

 bill; decidedly smaller and very much darker and browner than I^. s. 

 alaudinits, with black dorsal streaks very much broader, the under 

 parts much more heavily streaked with black, and in winter plumage, 

 with the chest, sides, etc., strongly tinged with brownish buff. 



Adult male.—hength (skins), 116.06-127.00 (120.90); wing, 63.75- 

 71.12 (67.06); tail, 44.20-50.80 (48.01); exposed culmen, 10.16-11.43

Adult feinale.— 'Length (skins), 111.76-118.11 (115.82); wing, 

 62.74-68.38 (64.77); tail, 43.18-18.77 (46.23); exposed culmen, 10.16-

Coast of California (salt marshes), breeding chieflj'' about San 

 Francisco Bay; occasionally southward in winter to central Mexico 

 (Valley of Mexico). 



[The type specimen of ATrnmodvam/us sandwichensis lyrutvnescens 

 Butler agrees minutely with examples of this form from the coast 

 of California. There is no yellow whatever 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 superciliary or supraloral region. 



An adult female fromTlalpam, 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.]
