 nigro-fusco notato. 



Adult Male (Tangier, April) . Upper parts dark brown, the feathers on the head and back only brown on 

 the terminal portion, all the rest being pure white, which colour shows through here and there ; the 

 brown terminal portion of the feathers on the back, scapulars, and wing-coverts slightly edged with 

 light brown, those on the head and nape being more broadly and lighter edged ; quills blackish brown, 

 with a slight purplish gloss, the primaries on the basal and outer half of the inner web white, barred 

 and marbled with dark brown ; secondaries on the inner web slightly marbled with greyish white ; 

 wing-coverts like the back, but on the basal portion marbled with dull grey and not white ; rectrices 

 greyish brown on the outer web, and light whitish brown or grey on the inner web, except the two 

 central ones, which are brownish grey on both webs, all being crossed by six or seven bars and one 

 very broad subterminal band of dark blackish brown ; sides of the head pale sandy yellow or rufous 

 buff, striped with black ; underparts white, marked all over, but less on the breast than elsewhere, with 

 elongated drop-shaped stripes of black, and on the abdomen sbghtly washed with pale reddish buff; 

 feathers on the tibia and tarsus white, washed with rufous buff, and striped with blackish brown; 

 under tail-coverts white, barred and marbled with dull light reddish brown ; edge of the under surface 

 of the wing and axillaries variegated blackish brown and white; larger under wing-coverts dull 

 blackish, slightly tipped with white ; feathers on the flanks tipped with blackish brown ; bill blackish 

 horn, dull bluish at the base ; cere and feet yellow ; iris orange brown. Total length about 26 inches, 

 culmen 2 - l, wing 18*6, tail 116, tarsus 3 - 8. 



Adult Female. Resembling the male, but larger. 



Young Female (Butrinto) . Resembles the male last described, but has the upper parts much more umber- 

 brown in shade of colour, and the entire underparts are dull reddish, tolerably closely striped with 

 blackish brown, the throat and upper breast being dull dark foxy red ; the feathers on the tibia and 

 tarsus dull rufous, narrowly striated with blackish. 



Nestling (Acarnania, March 1873) . Head and neck covered with close white down, through which on the 

 crown and nape the brown feathers are appearing ; back, wings, and tail dark earth-brown, with a faint 

 purplish gloss ; the wing- and tail-feathers, which are very short, having lighter tips ; underparts partly 

 covered with white down and partly with rusty red feathers, most of which have a dark blackish brown 

 central stripe. 



Obs. Besides my own specimens, I am indebted to Canon Tristram for the loan of a beautiful series of 

 specimens of this Eagle, embracing all stages of plumage from the nestling to the very old bird : and 

 Mr. Saunders has also placed at my disposal some beautiful specimens in his collection. A young 

 bird in Canon Tristram's collection, which is in the first feather-plumage, resembles the nestling above 

 described, but is rather younger. A young female, shot by Canon Tristram himself at Biskra, has the 

 upper parts very dark, and the underparts rather peculiarly marked, the feathers being white at the 

 base and reddish towards the tip, the centre of the terminal portion being covered by a broad drop- 

 shaped blackish brown mark ; the feathers on the abdomen are also marbled, even on the basal portion, 

 with dull reddish brown. Another immature bird, obtained by Mr. W. E. Brooks, of Etawah, has the 

 upper parts dull earthy brown, and the underparts pale rufous, the feathers narrowly striated along 

 the centre with blackish brown ; the abdomen and thighs being very pale rufous buff, the latter 

 unstriated. The adult birds are like the male above described; but several in both collections, 

 especially two in that of Mr. Saunders, are very white, and but little marked on the underparts.
