The fii-st locality where we met with tliis species in traveling eastward, 

 was the eastern slope of the Ruby Mountains, where several other species 

 characteristic of the Rocky Mountain district were first encotmtered, as 

 Hchninthophaga Virginia; and Selasj^fiorus platijccrcus. It was rather common 

 in July and August, its usual abode being the cedar and nut-pine groves on 

 the lower slopes of the mountains, along Avitli Bendronca nigrescens and Ucl- 

 minthophaga virginicE, or in the brushwood of the ravines. Certain of its 

 notes so closely resembled those of Troglodytes parhnanni that they were 

 liard to distinguish.

This ^'ireo was the characteristic and most abundant species at Sac- 

 ramento City, where it inhabited the dense willow copses along with 

 Empidonax pusiUus. It was not observed anywhere else during our explo- 

 rations, and it is probable that its northward range in California is limited 

 to the immediate vicinity of the Sacramento Rivei-. Its notes most resemble
