Characters. This remarkable type agrees very nearly with Masius, but differs by 
its much greater size and relatively much longer tail. The erect frontal plumes are 
much longer and nearly straight, not curly. In the wing, the fourth primary is the longest, 
the third and fifth are very little shorter, the first is equal to the eighth. The rectrices are broad 
and almost square at the end. The tail is strongly rounded, the outermost pair of rectrices being 
about 8 to 10 mm. shorter than the innermost. The bill is of the same shape as in Masius, 
perhaps somewhat more curved at the tip. In both genera, there is a distinct notch near the 
end of the upper mandible, Feet dark brownish red in the skins. Metatarsus distinctly scutel- 
late. Sexes different in coloration. The general plumage of the male is velvety black. Erect 
frontal plumes, pileum, nape and upper back beautiful scarlet, the feathers of these parts being 
(1) The 2° are not distingimshable.
