492 Notes on Mr. R. B. Sharpens 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, M'ith 

 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 mfescent 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
