21. Psaltriparus plumbeus Baird. Lead-colored Tit.—Of the eight specimens of this species which are included in the collection, seven were taken in the Chiricahua Mountains, the remaining one being from the Santa Rita Mountains. Mr. Stephens does not appear to have found it elsewhere, and in his notes characterizes it as rather uncommon. It was oftenest seen among the oaks of the foot-hills, where it associated with Wollweber’s Titmouse, the Ruby-crowned Kinglet, and several other small birds.
