Adult. Above velvety black, the crown glossed with bronzy green, 

 the back with dark green, the hind neck, rump, and upper tail- 

 coverts with purple ; across the lower back a band of dusky grey ; 

 scapulars pure white ; wings glossy black, with dark green reflections 

 on the least wing-coverts, primary-coverts, and primaries ; the greater 

 coverts intense purple, varying with a shade of blue, the secondaries 

 purplish blue, vaiying to deep green with the light, and shading 

 into dull bronzy purple on the outer webs of the innermost, which 

 arc distinctly green interiorly ; aU the primaries white for the greater 

 part of the inner web ; centre tail-feathers dull bronzy purple, 

 shaded with blue on the inner web and with green at the" base, all 

 the other feathers dull greenish black, the outer webs bronzy purple 

 on the outer edge, shading through indigo to bright green, and thence 

 to copper and bright purple, these varying shades intensified towards 

 the upper portion of the feather, the extreme end of the web being 

 green ; sides of head, neck all round, throat, and chest velvety black, 

 glossed slightly with purple, rest of under surface white ; thighs 

 greenish black ; under wing- and tail- coverts purplish black, the 

 edge of the wing greenish ; bill bright yellow ; legs black. Total 

 length 13-5 inches, culmen 1-35, wing 7-65, taU 9-5, tarsus 1-65. 



Obs. JCone of the Museum specimens having their sexes accurately 

 determined, I have described the brightest-looking with pure yellow 

 bill as being probably the adult male. The bronze-coloured tail- 

 feathers look like a sign of immaturity, as aU but one of the other 

 specimens have the centre tail-feathers green, and the white on the 

 quills reaches within half an inch of the extremities of the feathers ; 

 one specimen has one of the long median tail-feathers green and 

 the other bronzy.
