540 SYSTEMATIC SYNOPSIS. —RAPTORES — ACCIPITRES. 
the throat, neck all around, and more or less of@fe back and breast whitish, spotted and chietly 
barred with blackish ; upper and under tail-coverts and most of the tail white, the latter very 
numerously barred with blackish, of which color is the broad terminal zone; the shafts white 
along the white portion of each feather. Basal portion of primaries likewise barred with 
whitish. Bill variously pale colored; cere carmine; iris brown; feet yellow ; claws black; 
soft parts drying to a dingy indefinable color. Young similar, but rather brownish, the mark- 
ings of the body in lengthwise streaks, not cross-bars ; tail, however, barred. Length (either 
sex) 21.00-23.00; extent about 48.00; wing 14.50-16.50; tail 8.00-10.00; tarsus about 3.60;

middle toe without claw 2.00. I describe the N. Am. bird, which is much less extensively 
barred than that of S. Am. (See Cassin, Pr. Phila. Acad., 1865, p. 2.) The difference in 
several specimens handled is striking, nearly the whole body, wings, and tail of the 8. Am. bird 
being multitudinously rayed across, while in Texas and Florida specimens the body anc wing- 
coverts are mostly uniform, the barring being restricted to the neck and fore half of the body, 
and to the primaries and tail-feathers. If I have compared age for age, the bird is certainly 
different. P. lutosus is barred throughout, and otherwise different again. S. border of U. 3..
