 Slate-coi.ored Sparrow. — None were met with during 1S81, 

 but I have a specimen taken bv Mr. Stephens near Tucson, in 

 Febniarv. iSSo. 



78. Pipilomaculatus inegalonyx(/?«/;'t/) Co/^o-. Spurred 

 TowHEE. — Two males, Chiricahua Mountains, March 36 and 

 38. "Common in brush, usuallv along streams. Thev have a 

 variety of calls, some of which resemble those of the Catbird. 

 The song, uttered while the bird is sitting on a tree, soimds like 

 jack-Jacksonii." 



The North American Towhees of the nniciihifrt^ group are at present 

 involved in much confusion. The trouble seems to be that each localit\- 

 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 tilings obtains among the Song 

 Sparrows, Shore Larks, and several other species, in which the forces of 

 evolution are still activel\- working. 



79. Pipilo chlorurus {Towns.) Baird. Green-tailed 

 TowHEE. — vSeveral specimens taken late in April. "■Not com- 

 mon : usuallv found m low brush." 



80. Pipilo fuscus mesoleucus {Baird) Ridgxc. Canon 

 TowHEE. — ■•Common in rock\- localities on plains, and in val- 

 leys." A nest containing three eggs was taken June 15 at a point 

 about twentv-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 didl la\'ender 

 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 firmh and rather compactly Iniilt of hlirous slireds
