ceeds a broad black streak down the side of the J-P«egri. 

 head, in the form of mustachoes. This charac- 

 ter is seldom so distinct in the female as in the 

 male, and is scarcely perceptible in very young 

 birds of either seji. The under parts are pale, 

 with transverse blackish-brown bars. These 

 markings commence on the lower part of the 

 breast, and descend to the vent-feathers. The 

 feathers on the sides and thighs are likewise 

 crossed, and it is on these parts, when the bird 

 begins to assume its perfect plumage, that the 

 transverse markings are first discernible. The 

 throat is pure. The upper part of the breast is 

 characterised by a few longitudinal streaks. Tail 

 black, with numerous transverse cinereous bands, 

 and yellowish- white at the tips. Legs yellow ; 

 claws black. The old and young birds bear the 

 same relation to each other as those of the Gos- 

 hawk. The old are transversely marked, the 

 young longitudinally ; and intermediate birds oc- 

 cur, with some parts transverse, some longitudinal. 

 As the Sparrow Hawk may be said to represent 

 the Goshawk in miniature, in like manner, the 

 Hobby nearly resembles the Peregrine, before the 

 latter has assumed the transverse markings. 



In the Goshawk, the breast has a light bluish 

 tinge, in the Peregrine a brownish one ; and in 

 the former, I have remarked, that the perfect 

 plumage of the under parts is first acquired, but 

 in the latter, the longitudinal spots on the breast
