The first locality where we met witli this species in traveling eastward, 

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

 characteristic of the Rocky Mountain district were first encountered, as 

 IL'Jmirifliophaga virginice and Sclasplwrus platycercus. It was rather conmiou 

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

 the lower slopes of the mountains, along with Bendmca nigrescens and Hel- 

 minthopliaga virgbua; or in the brushwood of the ravines. Certain of its 

 notes so closely resemlded those of Troglodytes 'parhnanni that they were 

 liard to distinguish.

This Mreo was* the characteristic and most abundant species at Sac- 

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

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

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

 to the iunnediate vicinity of the Sacramento River. Its notes most resemble
