A single specimen was taken at old Camp Goodwin, Ariz., and occa- 

 sionally an individual was met with among the mesquite ti-ees along the 

 Gila River. The habits, so far as observed, seemed to resemble those of 

 the Titmice, as does also its great variety of notes. 



In 1874, I met with the species but once, at Camp Lowell, Ariz., in 

 September. This seeming rarity of the species in a region well adapted to its 

 habits was probably due to the lateness of the season at which our visits to 

 Southern Arizona have been made ; it probably having departed to a more 

 consfenial winter habitat farther south.
