Adult male. Upper surface sandy brown, strongly inclined to 

 rufous, with which colour most of the feathers are edged, excepting 

 the scapulars and inner secondaries, where the margins incline to 

 fulvous ; the feathers of the lower back, rump, and upper tail-coverts 

 broadly tipped with rufous ; head a little lighter than the back, with 

 blackish shaft-stripes ; forehead, lores, and an indistinct eyebrow 

 whitish ; nape scarcely at aU mixed with white ; sides of the face 

 creamy white, the sides of the neck slightly washed with rufous and 

 narrowly streaked with brown; a narrow supraorbital line of feathers, 

 as well as a moustachial streak, from the fore part of eye down the 

 cheeks and the hinder part of ear-coverts, dark brown ; under surface 

 of body creamy white, with brownish shaft-stripes ; thighs, axil- 

 laries, and inner under wing-coverts chestnut ; outer wing-coverts 

 white ; quills dark brown, with a slight tinge of ashy grey, the 

 secondaries paler brown, with rufous-white tips, inner surface of 

 wing white, the inner webs barred with rufous above, each bar being 

 almost continuous with the preceding one on the primaries ; tail 

 brown, tipped with white and shaded with ashy, barred with rufous, 

 the bars not being continued entirely across the feather ; cere pale 

 yellow ; orbits bluish flesh-colour ; bill bluish lead-colour, black at 

 tip ; feet light ashy grey, tarsal scales in front yellowish white ; iris 

 brown. Total length 15-5 inches, culmen 1'15, wing 13, tail 7"8, 

 tarsus 2-55. 



Adult female. Similar to the male, but a little larger. Total length 

 17 inches, culmen l-l, wing 14, tail 8-8, tarsus 2-8. 



Young. Similar to the adults, but plainly spotted and banded with 

 rufous above, especially on the wing-coverts and inner secondaries ; 

 under surface of body for the most part pale sandy rufous, mottled 

 with creamy white, where the plumage shows signs of approaching 

 adolescence ; thighs deep chestnut-brown, with faint cross bars of 

 rufous ; the facial features more pronounced than in the adult. 



Obs. The possession by the Museum of the original types of Hiera- 

 cidea benc/ora, which were received from the Linnean Society, en- 

 ables me to prove that the II. occidentalis of Gould is the true H.
