492 Notes on Mr. R. B. Sharpe’s Catalogue of Accipitres. 
with the exception of being white at the base, are greyish 
brown, mottled with darker spots of the same colour; the 
crown of the head, the cheeks, and the neck are rufescent- 
fulvous, with dark brown shaft-marks; and a similar style of 
coloration and markings pervades the lining of the wings and 
the remaining portion of the under surface of the body, with 
the exception of the sides of the upper breast, which are dark 
brown, and of the thighs, which are also dark brown but with 
rufous tips to some of the feathers. 
Mr. Sharpe does not describe the immature plumage of H. 
coronatus. The youngest specimen of it which I have seen 
is preserved in the Museum of the University of Cambridge, 
and is considerably more advanced towards maturity than the 
immature specimen of H. solitarius above described, from 
which it chiefly differs in the greyer tint of its dark, and the 
paler hue of its rufescent parts, and also by its slightly more 
developed occipital crest; it shows remains of rufous colouring 
on the tertials, but not on the secondaries; the upper tail- 
coverts are dark grey, with whitish edgings; the tail is as in 
the adult bird, with the exception of the two outer pairs of 
rectrices, which resemble the corresponding feathers in the 
immature H. solitarius , but with rather more white upon 
them; the wing-linings resemble those of the young H. soli¬ 
tarius, but the rufescent portions are paler, and with more 
or less white on several of the feathers; the feathers on the 
flanks are pale fulvous, with very long dark shaft-marks ; the 
rufescent edgings to the tibial feathers are broader than in 
the young H. solitarius; the under tail-coverts are pale buff, 
with one or two transverse bars of chocolate-brown on each 
feather; and I may also mention that the plumage of the head 
exhibits an especially noticeable pale fulvescent mark running 
backwards from above the centre of the eye. 
Mr. Sharpe mentions this streak behind the eye in his de¬ 
scription of the adult plumage; but in fully adult birds it dis¬ 
appears, as does also the whitish hue on the sides of the face 
and neck, and the chocolate gloss on the mantle, to which Mr. 
Sharpe refers, his description being taken from a specimen 
not entirely adult; in old birds these tints are all ultimately
