The specimens enumerated above represent true boucardi and are readily separable from Texas examples by the characters which my friend Mr. Brown has lately pointed out[[93]] in his diagnosis of the new race, eremœca.

76. Melospiza lincolni (Aud.) Baird. Lincoln’s Finch.—“Common along streams” in March. Two specimens (Cave Creek, March 5).
77. Passerella townsendi schistacea (Baird) Coues. Slate-colored Sparrow.—None were met with during 1881, but I have a specimen taken by Mr. Stephens near Tucson, in February, 1880.
78. Pipilo maculatus megalonyx (Baird) Coues. Spurred Towhee.—Two males, Chiricahua Mountains, March 26 and 28. “Common in brush, usually along streams. They have a variety of calls, some of which resemble those of the Catbird. The song, uttered while the bird is sitting on a tree, sounds like jack-jacksonii.”
