by William Swainson

“ Bill thin, short, very much depressed, broader than the front of the head; the upper mandible abruptly hooked and notched at the tip; the margins dilated, and folding over those of the under mandible; nostrils central, the base covered with a membrane having minute feathers, the aperture small, round, terminal, and nearly naked; mouth large, armed above with stiff bristles; feet sitting, slender; lateral toes unequal, exterior united to the middle as far as the first joint; hinder claw strongest. ”

“ Leadbeater. The figure of P. cancromus of Professor Temminck, differing only from this bird in having a yellow crest, leads me to believe they are sexes of the same species; this being the female bird. ”
