76. Melospiza lincolni (And.) Baird. Lincoln’s Finch. 
— “Common along streams” in March. Two specimens (Cave 
Creek, March 5). 
77. Fasserella townsendi schistacea {Baird) Cones. 
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(AWrtf9 Cones. 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

The North American Towhees of the maculatus group are at present 
involved in much confusion. The trouble seems to be that each locality 
furnishes a race of its own which either possesses certain slight individual 
characteristics, or combines, in varying degrees, the characters of two or 
more recognized forms. The case, however, is not peculiar; for to a 
greater or less extent the same state of things obtains among the Song- 
Sparrows, Shore Larks, and several other species, in which- the forces of 
evolution are still actively working. 
79 - Pipilo chlorurus {Towns.) Baird. Green-tailed 
Towhee. — Several specimens taken late in April. “ Not com- 
mon ; usually found in low brush.” 
80. Pipilo fuscus mesoleucus {Baird) Ridgw. Canon 
Towhee. — “ Common in rocky localities on plains, and in val- 
leys,” A nest containing three eggs was taken June 15 at a point 
about twenty-five miles north of Tucson. The eggs are grayish- 
white with numerous, short, zigzag lines of black about the larger 
end and occasional spots or dashes of brown and dull lavender 
scattered over the general surface of the shell. They measure 
respectively .9iX*69, . 94X^69, and .92X -69. The nest, which 
was placed about four feet above the ground in a “cat-claw” 
mesquite, is firmly and rather compactly built of fibrous shreds
