 continuous, sharply defined broad bars, or narrow bands, of clear dusky brown. A broad 

 stripe of plain brownish black on side of head, beneath the eye, from rictus to end of 

 auriculars; a blotch of the same beneath the middle of the auriculars, and the top of the 

 head mostly blackish, leaving a broad superciliary and maxillary stripe, and the whole 

 throat immaculate buff. Neck-tufts 3.50 inches long, deep black; the longer ones uiniform, 

 the shorter with only the edge black, the whole middle portion pale buff, shading into 

 deep reddish rusty next to the black. Wing, D.OO; tail, 450; bill, .40 deep by .50 long, from

To describe in a work intended especially for Illinois readers 

 the habits of the Prairie Chicken, seems almost as superfluous 

 a proceeding as "carrying coals to Newcastle;" hence we omit 

 further reference to this species than the following brief account 

 of its nesting, from History of North American Birds. 



"This bird nests, according to the locality in which it is met 

 with, from the beginning of April to the last of May. In Ken- 

 tucky Audubon has found their nests with eggs early in April, 

 but the average period there was the first of May. Their nests 

 he describes as somewhat carelessly formed of dry leaves and 

 grasses, interwoven in a tolerably neat manner, and always 

 very carefully placed among the tall grass of some large tuft in 

 the open ground of the prairies, or in barren lands at the foot 

 of a small bush." 



Genus PEDIOC-ffiTES Baird. 



Pedioccetes Baled, B. N. Am. 1858, 625. Type, Tetrao phasianellus Linn. 



"Gen. Chab. Tail short, sraduated; exclusive of the much lengthened middle part, 

 where are two feathers (perhaps tail-coverts) with pai-allel edges and truncated ends, half 

 the full ronnded wing. Tarsi densely feathered to the toes and between their bases. Neck 

 without peculiar feathers. Culmeu between nasal fossae not half the total length."
