Colour. — Front and sides of head brilliant dark green (duck green,) top of 

 head, rudimentary crest, tertiary quill feathers, upper tail coverts and tail 

 splendid purple, changing in some lights to brilliant deep green, with a strong 

 metallic lustre. Neck, upper part of belly, shoulders, interscapulars and 

 breast intermediate between sap and oil green, the two last named parts 

 distinctly tinged with rusty orange; back greyish black, strongly glossed with 

 green ; hinder part of belly, flanks and thighs rusty blackish grey, faintly 

 shaded with green. Lesser wing coverts, and secondary quill coverts bright 

 lavender-purple, in certain lights changing to shining blue or purple ; 

 primary quill coverts, brownish red ; bastard wings deep purplish green. 

 Primary and secondary quill-feathers, bright crimson red, broadly tipt with 

 a light purplish brown and narrowly edged with dark metallic green ; the ter- 

 mination of the crimson is separated from the purplish brown by a light 

 yellowish brown line. The extent of the crimson is less upon the outer than 

 upon the inner vanes, and is entirely wanting upon the outer vane of the 

 first feather ; the bases of several of the innermost secondaries deep purplish 

 brown ; the shafts of the quill-feathers clear reddish brown ; insides of 

 shoulders dusky blackish brown, edged externally with greenish grey. Bill, 

 legs, and claws, deep reddish black. 



Form, &c. — Bill naked and short, broad at the base, and compressed 

 towards the point ; nostrils oval, nearly midway between the base and apex 

 of the upper mandible and nearer to the culmen than the commissure, the 

 latter slightly undulated. Head with a flattened and rudimentary crest of 

 rigid feathers, which projects but little beyond the nape. Wings large, rounded.
