370 A FIRST LIST OF THE BIRDS 
Structurally and in dimensions this specimen agrees pre- 
cisely with the specimen I formerly described, only (as might 
be expected in an older bird) the feet and claws are a trifle 
more massive and powerful. 
The general plumage is a very uniform, moderately pale, hair 
brown, verging somewhat to umber, but the breast and middle of 
the abdomen are much variegated with ferruginous brown 
feathers broadly tipped and, in some cases, margined, with 
rufescent buff. 
The lower tail coverts are fulvous white, broadly margined 
with rufous and rufous buff, and with traces of imperfect 
brown bars on these margins. On the nape and inter- 
scapulary regionis an immense patch of feathers, white on their 
basal halves, and buff in some, deep ferruginous in others, 
on their terminal halves, all brown shafted, and some with 
narrow brown shaft stripes. The wing lining is mingled deep 
ferruginous and brown. large portions of the huge white 
wing patch described in the former specimen are in this pre- 
sent bird mottled over with a brownish grey, and this is the 
colour of those portions of the outer webs of the earlier 
primaries which were white in the former specimen, The 
tail is like that of many jferow, a grey brown, tinged with 
rufous towards the tips, everywhere browner towards the 
margins, with 3 or 4 transverse irregular bars towards the 
tips, and zig-zagey traces of 4 or 5 others higher up. 
The presumed male is a somewhat smaller bird. 
Length, about 24; wing, 19; tail, 11-0; tarsus, 3:4; bill from 
gape, 2:0; mid-toe and claw, 2:0; hind toe and claw, 1°62 ; 
bill along culmen from edge of cere to point, 1:03; hind-toe 
claw along curve, 1:2; inner do. do. 1:13 ; mid do. do. 0°7. 
Although the bill measured from the gape in this skin is 
as long as in the former specimen, it is really considerably 
smaller and feebler, and though the claws are nearly as long, 
they as well as the toes are feebler and slenderer. 
The large size of the inner toe claw far exceeding that of 
the mid, and all but equalling that of the hind toe is a marked 
peculiarity of this species, shared though in a minor degree by 
aquilinus. Another noteworthy point is the very considerable 
dilation of the inner edge of the mid toe claw. 
The whole bird is a very deep umber brown, almost blackish, 
deepest on quills, tail, abdomen, lower-tail coverts, and tibial 
and tarsal plumes. The latter quite conceal the foot in this 
specimen, are somewhat shorter in the female above described, 
and shorter still in that first described (S. F. p. 1, loc cit). 
Some of the longer upper tail coverts exhibit a few oval 
white spots. The basal halves of the central tail feathers exhibit
