equal*. The inner and hind toes are also nearly 
equal in length, while in ours the hinder toe is 
much the shortest. The wings, again, are not so 
much rounded, — as the third quill is nearly the same 
length as the fourth and fifth, and consequently 
much longer than in A. f r ingill arius ; in other re- 
spects, as regards the bill, tarsi, and scales, the two 
birds quite agree. 
The delicate slate colour on the upper plumage 
of the male is only a shade lighter than that of the 
common sparrow-hawk ; it becomes much paler on 
the ears and sides of the neck, and leaves the chin 
and half of the throat entirely white ; this white is 
divided down the middle by a pale but very distinct 
dusky stripe, which extends for about an inch from 
the chin. From the lower part of the neck, the 
ground colour of the plumage becomes of a delicate 
fawn colour, which changes on the belly, vent, and 
tbighs, to white ; on these latter parts there are no 
markings, but the breast and body are thickly 
barred with transverse ferruginous or fawn lines, in 
the same manner as those on our sparrow-hawk, but 
closer together and not quite so broad. The quills 
are blackish, without any external spots, hut having 
the inner web for about half its length fawn white, 
and banded with black ; these hands, however, can 
scarcely he seen on the under surface, and then only 
when the wing is opened. The inner wing-covers 
are marked with a few bars, wider apart than those

been noticed by any writer.
