 a broad line passing from the base of the bill over the head, widening out to 

 the full width of the neck and reaching down to the back, rich dark 

 golden brown ; feathers at the base of the upper mandible the same rich 

 colour; sides of the neck, chin, throat and upper breast white, tinged with 

 pale shining fulvous ; tail white, with a trace of black at the base, remainder

 strong on the back and scapulars ; the first and second primaries tipped 

 slightly with white ; eyelashes black ; the base of the casque and basal

 and yellowish on the ridges ; the terminal two-thirds of the bill pale yellow ; 

 gular skin bright gamboge yellow ; eyelids pinkish flesh colour, the edges 

 red ; iris bright pink ; legs and claws dark brown. The female has the 

 tail white as in the male ; with this exception, the whole plumage is black.
