centre of the abdomen white, marked with strong zigzag bars of 
black, changing into spots of white, bounded above by black on the 
flanks, all these marks being very brilliant ; eyelash dark olive ; irides 
dark reddish hazel; bill black ; legs yellowish white. 
Total length, 84 inches ; bill, ;; wing, 44; tail, 27; tarsi, 1}. 
Weight 54 ounces and 20 grains avoirdupois. 
Hab. South America; locality unknown. In my own collection. 
Remark.—Rather larger in all its measurements than O. Virgini- 
ana. From the general appearance of this bird, Mr. Gould is led to 
believe that it may hereafter prove to be a variety of some other 
species, probably of O. Virginiana ; at the same time its markings are 
so different and so decided in character that he has deemed it best 
to describe it provisionally, under a distinct appellation.

Male.—Naked skin before and behind the eye yellowish; bill 
black; crest rather lengthened and full; forehead and ear-coverts 
clouded chestnut, the former passing into reddish chestnut on the 
crown, and gradually brightening towards the occiput; throat and 
neck both before and behind grey, all the feathers margined with 
rufous; scapularies and wings (except the primaries) beautifully 
marked with rich chestnut, buff and black, the black predominating 
on the scapularies, which feathers are rendered very conspicuous by 
having a whitish buff line down the centre; the tertiaries also are 
marked with a bold edging of rich buff, bounded on the inner side 
by a well-defined band of black, which surrounds the feather, while 
the buff occupies the upper edge only; at the tip of all the wing- 
coverts is a triangular spot of buffy white; primaries blackish brown, 
marked on their outer edge with indistinct but regular bars of red- 
dish brown ; back and rump dull greyish buff, each feather minutely 
dotted and freckled with brown and black; tail-coverts and tail ru- 
fous brown and black, the markings and colour so disposed that 
neither predominate, being dispersed over each feather in alternate 
narrow zigzag lines, interspersed with minute dots and freckles; 
chest, abdomen and under tail-coverts rich rufous chestnut; the 
feathers of the chest with a small white mark in the centre, very 
nearly surrounded by a narrow irregular line of black, giving it a 
‘very sparkling appearance ; feet and legs in the dried specimen horn- 
colour. 
Female.—Differs in being smaller in size and in having the small 
white markings of the chest, being more lengthened in form and less
