38 NORTHERN ZOOLOGY. 



with soiled-white, and is crossed by five narrow bars of the same colour, of which the sub- 

 terminal one is the most perfect. Under surface. The throat is white. The cheeks, sides 

 of the neck, and breast, are brownish-white, streaked longitudinally with dark liver-brown. 

 The belly and thighs are white, with yellowish-brown streaks on the shafts. The flanks and 

 wing linings are yellowish-brown, with oval white marks. The quill feathers are barred alter- 

 nately on the inside with broccoli-brown and wine-yellow. The under tail coverts are white, 

 and the under surface of the tail is slate-coloured, crossed by white bars. Bill bluish-black. 

 Claws black. 



Form. — Shape of the bill much like that of F. sparverius. The cutting margin of the 

 upper mandible has a strong tooth near its tip, and is somewhat sinuated farther back. Lores 

 covered with white hair-like feathers, disposed in a stelliform manner. The tips of the folded 

 wrings reach within two inches of the end of the tail. The scapularies are short. The ter- 

 tiaries, or the posterior secondaries, are longer than the six preceding ones, and are equal to 

 the seventh or eighth primary. The wings have a pointed form : the second and third quill 

 feathers are the longest; the first is about half an inch shorter than these, and is scarcely equal 

 to the fourth ; the succeeding ones, to the eleventh, are successively shorter by half an inch 

 each. The outer webs of the second and third are rather suddenly narrowed near their tips, 

 and the inner webs of the first and second are more decidedly sinuated. The tail is' square. 

 The outside thigh feathers reach only half way down the tarsus. The tarsus is covered 

 anteriorly with feathers for nearly half an inch below the joint : it is protected at its base by 

 four transverse shield-shaped scales, and is reticulated elsewhere. The toes are long and 

 slender, particularly the middle one, and there is a roundish pad under each joint. The hind 

 toe is the shortest, but has the longest claw ; the inner fore toe comes next to it in length 

 and in the size of its claw. The bases of the middle and outer toes are connected by a 

 short web.
