found it at various localities of the Cape region. I found a 

 few at San Jorge in April. 



214. Ammodramus beldingi Ridgw. 



Belding's Marsh Sparrow. — The Marsh sparrow given in 

 Mi . Belding's list of San Quintin Bay species as Passercuhis 

 anfJimus (Bp.) is now known to be Ammodramus beldingi 

 which Mr. Anthony says is resident there. Mr. Belding re- 

 ports it from as far north as Port Harford (Alta California) 

 where it was rare. I obtained two immature birds on the 

 salt marsh south of San Quintin the last day of the overland 

 journey. 



215. Ammodramus rostratus Cass. 



Large-Billed Sparrow. — Found at San Jose del Cabo by 

 Mr. Xantus. Obtained at La Paz, Cape St. Lucas and other 

 localities by Mr. Beldiug. I found, among the bushes on 

 the sand hills near Magdalena village, a few of these sparrows 

 in February, 1888, and did not see them elsewhere. 



216. Ammodramus rostratus guttatus Lawr. 



St. Lucas Sparrow\ — First obtained at San Jose del Cabo 

 by Mr. Xantus in December, 1859. I secured a single male 

 on Santa Margarita Island, January 21, 1888, which Mr. 

 Bidgway says is most like fhe type specimen of any he has 

 seen. The bird is in good plumage and has conspicuous 

 yellow-stripes from nostrils extending back over the eyes, 

 brighter anteriorily. 



The type specimen measures: wing, 2.55 (64.7 mm ); tail,
