NOTE. The Troglodytes leucocjastra of Gould, supposed by Baird to be this bird, 

 has been shown to be entirely different. But as Gould's bird falls in a different genus, 

 Baird's name lcucogaster,o 1864, may be accepted for this variety. See Ibis, 1875, p. . 



This wren was found to be of rather common occurrence in Southern 

 Arizona, and to be generally, though rather sparingly, distributed throughout 

 Eastern Arizona from Camp Apache southward. It, without doubt, occurs 

 similarly in New Mexico. I know of nothing in its habits which peculiarly 

 distinguishes it from its eastern relative. It seems to prefer the thickets and 

 clumps of bushes on the open hill sides, where it spends much of its time 

 on the ground searching for food among the roots. Besides possessing the 

 usual variety of quaint, sputtering, wren-like notes, it has also a very pretty 

 song, which I have heard only once or twice. This was a short warbling 

 lay, much varied with low sweet trills, and occasionally interspersed with a 

 hoarse scolding- note.
