NATURAL HISTORY. 
9. F. Pyeareus. (Lin.) Will. 40. Ringtail. 
This bird is supposed to be the female i the 
Henharrier. There nas been considerable dif- 
ference of opinion amongst naturalists on this 
subject. Montague states the arguments on 
each side, but does not speak decisively. 
Latham also treats the subject very fuily in the 
supplement to his Synopsis. Pennant distinctly 
asserts that males ef the Ringtail have been 
dissected. 
10. F. Cineracevus. Mont. Orn. Dict. and 
Supp. Lin. Trans. 9, p. 188. Ash-colored Falcon. 
Montague considers that Pennant referred to this 
species in his variety of the Ringtail, 1. p. 195, 
and states that it differs from the Cyaneus in the 
greater length of the wings. In our opinion 
this is the young Henharrier: the difference 
in the plumage arises from age. 
11. F. Tintuncunvs. (Lin.). Brit. Zool. v. 1, 
p. 195. Kestrel. Common. This is the Hawk 
we so frequently see, fixed in the air and fanning 
it with its wings. 
12. F. Supsureo. (Lin.) Brit. Zool. v. 1. p. 197. 
Hubby. Rather scarce, found on the borders 
of Dartmoor, It feeds there, and migrates the 
latter end of Octuber. 
13. F. Hsaton. (Lin.) Brit. Zool. 1. p. 200, 
lierlm. Smailest of ail the Hawk kind, and 
rather scarce; it does not breed with us, but 
arrives about the time the Hobby leaves. It 
flies very low and with great celerity,
