128 Lord Walden on a further Collection of 
imparting a streaked appearance to this portion of the plumage, 
a distinct brown line descending from the chin to the breast. 
Under tail-coverts and axillaries pale dingy ferruginous brown 
irregularly barred with white. The elongated flank-plumes 
covering the thighs white terminated and blotched with pale 
ferruginous brown. Thigh-coverts pale ferruginous brown, 
those of the tarsus white, here and there speckled with brown. 
Head and nape clothed with lanceolate feathers, white at their 
base, the terminal and exposed portion of each centred with 
dark brown and margined with ferruginous. No crest-plumes. 
Remainder of upper plumage dark brown, each feather with 
more or less of paler marginal shading. Upper surface ofrec- 
trices the same. Middle pair with four narrow ill-defined 
but very dark brown transverse bars, and a broad terminal 
dark brown band fringed with albescent. The rectrices under¬ 
neath albescent, the brown bands strongly contrasting. Under 
wing-coverts white, irregularly but boldly banded with dark 
brown. Quills underneath albescent, with three or four dark 
brown transverse bands and tipped with the same colour. 
Basal half of the quills almost pure white. Quills above, when 
closed, dark brown. 
Wing 13*24 inches; tarsus 3*6; tail 10*4; bill from gape 
1*7; total length 21*8 (in the flesh). 
This Eagle is a crestless form of L. ceylonensis (Gm.)* and 
of L. cirrhatus (Gm.). The specimen above described is ab¬ 
solutely identical in plumage with a Candeish example of L . 
cirrhatus. It cannot be confounded with L. alboniger (Blyth) 
in any stage of plumage; for the adolescent plumage in that 
species is of a uniform buff, and when older, but before it has 
put on its handsome full dress of black and white, the mark¬ 
ings are ferruginous buff, and not brown. But the best dif¬ 
ferentiating character of L. alboniger is to be found in the 
first joint of the middle toe being feathered for full half its 
length,—a character it has in common with the much larger 
L. nipalensis , and which is also possessed to a less extent 
by the Celebesian representative form of that species, L. lan- 
ceolatus.
