Note.— The Troglodytes leucogastra of Gould, sui)posed by Baird to be this bird, 



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



Baird's name lcucoyaster,o{ 1804, 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 liill 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.
