narrow interrupted white lines, and, on the outer feathers, the broccoli-brown is replaced by 

 white mottled with brown. The ground colour of the under surface is white. The cheeks 

 are streaked with liver-brown. On the neck and breast the brown marks have an oblong 

 shape, and on the belly they are oval. The upper surface of the middle toe is scutellated 

 from the middle of the first phalanx to the claw, and reticulated at the base. The tail is 

 considerably rounded, its outer feathers being an inch and a half shorter than the middle

No. 4 is a specimen which was killed near Jasper's house, on the Rocky Moun- 

 tains. Its sex was not ascertained, but its plumage is very similar to that of the 

 preceding, though in a more perfect state. The tail is still more rounded, but 

 the feathers composing it are individually more acute and have a white tip half an 

 inch broad. The basal half of the middle toe is also more reticulated than that of 

 No. 2, resembling in that respect male No. 1. The total length of this specimen 

 is 29 inches. 



DESCRIPTION 



Of a specimen killed at York Factory, Aug. 14, 1822, supposed to be a young\Av& of that season. From the recent 



specimen*. 



Colour. — General tints of the dorsal aspect blackish-brown and ferruginous. On the head 

 the former colour forms an elliptical spot in the centre of each feather ; on the wings and 

 scapularies it occupies more space, the ferruginous tint being confined to a narrow border, 

 and sometimes to an irregular streak across the feather. The quill feathers are liver-brown, 

 slightly clouded with wood-brown. The tail is tipped with soiled-white, and has three or four 

 broad, but distant, bars on a broccoli-brown ground. There is a slight intermixture of white 

 on the tail coverts. The under surface of the neck and body and the linings of the wings are 

 wood-brown, with elliptical black marks. Towards the vent the feathers are almost white, 

 with black shafts. The under aspects of the quill and tail feathers are yellowish -grey, barred 

 with brownish-black. Bill bluish-grey at the base, blackish at the tip : the cutting margin of 

 the upper mandible slightly sinuated. Cere orange-coloured. Eyelid greyish. Iris sulphur- 

 yellow. Tarse yellow. Length, 24 inches ; extent, 43 ; length of the tail, 12 inches. 



* This is the specimen noticed by Mr. Sabine in Franklin's Journey.
