summer they scatter to orchards and gardens, where they 

 nest. I have found them only in mountainous couatrj^ 

 where there was abundance of water, from Comondu as far 

 north as lat. 29°. None were seen on the islands. 



169. Tyrannus verticalis Say. 



Arkansas Kingbird. — One pair seen at San Quintin Bay 

 May, 1881, by Mr. Belding. 



170. Tyrannus vociferans Swaius. 



Cassin's Kingbird. — Kecorded from the Cape region and 

 Cerros Island by Mr. Belding. Mr. Anthony found it nest- 

 ing in live oaks and cottonwoods up to about 4,000 feet alti- 

 tude, and thinks he has seen none after the middle of No- 

 vember. I secured a specimen near Pozo Grande, and 

 occasionally saw them farther north. 



171. Myiarchus cinerascens Lawr. 



Ash-throated Flycatcher. — One of the most generally 

 distributed species found in Lower California. Mr. An- 

 thony says that along the northwestern coast he has found 

 them nesting in the dry flower-stalks of Agave. 



172. Sayornis say a (Bonap.) . 



Say's Phcebe. — From the Cape region and vicinity of San 

 Rafael, Mr. Belding says it is rare; he and myself found 

 them on Cerros Island. On Magdalena Island, February 

 23, 1889, I shot a very pale-plumaged male; the previous 

 year I saw them at several places on the peninsula. Mr. 

 Anthony has found the nests of this species in old mines 

 and tunnels at Valladares, frequentty at a depth of twenty 

 feet in a shaft. Mr. Belding saw it at Tia Juana and San 

 Rafael in the middle of May, 1885, in a mining shaft at the 

 latter place. 



173. Sayornis nigricans (Swaius.) 



Black Phcebe. — One specimen was collected by Mr. 

 Xantus at Cape St. Lucas, and Mr. Belding found it rare at 

 the Cape region and between Tia Juana and San Pedro
