NOTOPHOYX. 
Tonojpihoyx is quite differently coloured to the two preceding and has an 
elongated crest with long dependent nape-plumes, long lanceolate dorsal 
ornamental feathers, and a full breast-ornament of pointed lanceolate feathers. 
The bird is much smaller, with a proportionately longer and stouter bill, but 
rather short legs. A key might be given thus : — 
Wing over 300 mm. 
Metatarsus over 150 mm. . . . . . . . . . . My oh. 
Metatarsus under 150 mm. . . . . . . . . Notophoyx. 
Wing under 300 mm . . . . . . . . Tono'phoyx.
