interscapulium are rufous at the base; the upper and under tail- 
coverts are margined narrowly with white; the tail has a broad 
white cross band, above this is another much narrower and not quite 
complete, a third, still narrower and ill-defined, is placed at the base 
and hidden by the tail-coverts; the tail-feathers are tipped with 
white ; the under surface of the wings shows a white space, formed 
by the white basal third of the first four primaries, but this white is 
speckled very minutely with greyish black, as in H. anthracinus ; the 
secondaries bear on the middle portion of the inner web six or seven 
cross bands of pale rufous brown, somewhat ill-defined and mixed 
and washed with dark brown, giving a somewhat marmorated ap- 
pearance. 
This species is closely allied to H. anthracinus, Licht., but may 
be easily distinguished by the two white bands on the base of the 
tail, besides the white middle cross band.

Two specimens of this fine species :—one in the well-known plu- 
mage of the old bird, as described by Prince Max, Dr. Léotaud, and 
others; the other in the very different plumage of the younger 
stage, of which I cannot find any description. I therefore add a 
detailed account of this specimen. 
Head, neck, upper portion of the interscapulium, and all the under- 
parts white, tinged faintly with pale ochre on the sides of the head 
and neck; the sides of the belly and the under wing-coverts with 
large cordiform black spots, as in the old bird, the feathers on the 
femur and tarsus likewise barred transversely with white and black ; 
shoulders, wings, and tail dark brown, and marked with darker bars 
as in the old bird, but not so distinct; the tail with six broad cross 
bands of brownish black; the upper quill-coverts margined with 
white at the point, as in the adult; on the occiput there is a consi- 
derably long crest, composed of some black, brownish, and whitish 
feathers, which are strongly worn off, showing that the bird is not a 
very young one; on the hind neck some feathers of a rufous brown, 
as in the old bird, which indicate evidently that these parts are 
assuming the colouring of the adult.
