broad, slightly emarginate or abruptly rounded ; of the back, 

 broad and rounded ; of the rump, elongate with loose fila- 

 ments ; of the sides, very long ; of the abdomen, downy ; of 

 the legs, soft and rather short. There is the same tuft of 

 small feathers over the ear. The wings and tail are precisely 

 similar, even to the concavity of the extremities of the longer 

 feathers of the latter. 



"The bill is horn colour, or greyish-yellow, tinged with 

 green ; the nasal operculum, flesh colour. The iris is yellow, 

 and the bare papillar space about the eye, crimson. 



"The upper part of the head is brownish-green, the fore- 

 head, sides and tuft, deep green. The upper part of the neck 

 is deep blue, glossed with purple and green, the latter pre- 

 dominating behind. At the lower edge of this dark-coloured 

 part is a white band, extending along two-thirds of the 

 circumference of the neck, narrow behind, broader at the two 

 anterior extremities. This band is composed of white tips 

 only. The rest of the fore-part of the neck is of a rich 

 coppery tint, glossed with purple in some lights, fading below 

 into brownish-yellow, of which colour also are the sides. On 

 the neck and breast each feather has a terminal margin of 

 purplish-blue, which in some lights is black. This margin is 

 distinctly indented, but the emargination gradually disappears 

 on the lower feathers. The middle and lower part of the 

 breast is blackish-brown, glossed with green. The fore-part 

 of the back is yellowish-red, each feather slightly margined 

 with black, and having a central oblong spot of the same. 

 The scapulars are redder, with a slight black tip, the central 

 part dull yellow mottled with dusky, and margined with a 

 black band. The hind part of the back is confusedly varie-
