brush along mountain rivulets, and similar situations, where the seeds of 

 various plants are procurable ; its general habits resemble those of the species 

 of Zonofrichia." 



The nests were found by Mr. Eidgway in various situations ; the larger 

 number were upon the ground, but several were in trees varying in heiglit 

 from six to twenty feet Irom the ground. They were found from the latter 

 part of May through June. A nest obtained in Southern Wisconsin by Mr. 

 Thure Kumlien is very homogeneous in structure, consisting entirely of 

 loosely intertwined stems of dry grasses, sedges, and carices. It was built 

 on the ground, is nearly Hat, and has only a very shallow cavity. Its entire 

 height is less than two inches, and the depth of its depression not half an 

 inch. The diameter of tlie nest is three and a half inches, and that of the 

 cavity at the rim three inches. 



The maximum number of their eggs is five. Their average measurement 

 is .85 by .65 of an inch. The ground-color is usually a grayish-white, 

 rarely a light brown, marbled and streaked with waving lines, and a few dots 

 of black or a blackish-brown.

 the most beautiful of American 

 Sparrows, all of the largest 

 size in their subfamily. zonotridua kucophrys. 



All the species properly belonging to this genus are North American ; 

 several South American species, have, however, been assigned to it ; but 

 they are none of them strictly congeneric with those given below.
