Crown of the head, ear-coverts and throat rich brown, each feather surrounded with a narrow line of black; feathers on the crown small, and tipped with silvery grey; a beautiful band of elongated feathers of light rose-pink crosses the back of the neck, forming a broad, fan-like, occipital crest; all the upper surface, wings and tail of a deep brown; every feather of the back, rump, scapularies and secondaries tipped with a large round spot of rich buff; primaries slightly tipped with white; all the tail-feathers terminated with buffy white; under surface greyish white; feathers of the flanks marked with faint, transverse, zigzag lines of light brown; bill and feet dusky brown; irides dark brown; bare skin at the corner of the mouth thick, fleshy, prominent, and of a pinky flesh-colour. Both sexes, when fully adult, are adorned with the rose-coloured frill; but the young birds of the year, both male and female, are without it. The Plate represents the bower, with two birds, a male and a female, all of the natural size. [Illustration: CHLAMYDERA NUCHALIS. _J. & E. Gould del et lith._ _C.
