No. 7, another young male, killed a few days earlier at the same place, scarcely 

 differs a shade in the colour of its plumage, and corresponds minutely with the 

 preceding- in form. The plumage of both is considerably worn. 



DESCRIPTION 



Of (No. 8.) a yearling female ? killed, in the end of September, at Great Bear Lake, a few days before the departure of 



all the migratory Falcons to the southward. 



Colour of the dorsal aspect considerably deeper than in the preceding young male, being 

 intermediate between umber and blackish browns, and it has a strong bronze reflection. The 

 narrow edgings of the feathers of the crown, and the broader ones of the neck and wing 

 coverts, are deep shining orange-brown. The quill feathers and their coverts are blackish- 

 brown ; the upper halves of their inner webs are white and wood-brown, with three cross bars 

 of dark-brown. The tail coverts are white, edged with pale yellowish-brown. The two middle 

 tail feathers have five brownish-black bars, alternating with clove-brown. On the other tail 

 feathers the bars are separated by reddish-orange spaces. The under plumage presents gene- 

 rally a deeper orange-coloured brown than the young male above described. 



Form, &c. — The bill differs from all the other seven specimens in its cutting margin being 

 almost straight, with scarcely an indication of the lobe. The tail is more rounded, from the 

 perfect state of the individual feathers. The tarsus has fourteen scutelli anteriorly ; but its 

 upper half posteriorly is reticulated by smaller scales. The third quill feather is the longest; 

 the fourth is scarcely perceptibly shorter; the second and fifth are about an inch shorter; the 

 sixth is two inches shorter than the fifth ; and the first is exactly intermediate between the 

 sixth and seventh. The whole plumage is in high order; all the feathers rounded at the tips 

 and soft on the edges.

On Sir John Franklin's first Expedition I killed a specimen on the shores of 

 Hudson's Bay (lat. 57°), on the 23rd of August, which very nearly resembles the 

 preceding, but, being less spotted, is probably an older female. It corresponds 

 exactly with Wilson's figure of the female Marsh Hawk (F. uliginosus), to which 

 Mr. Sabine referred it. This gentleman makes the following observations upon
