Male. Bill and feet very weak and obscure in colour. Two flattened 

 fan-shaped crests, each composed of six small feathers, part from the 

 forehead on a level with the eyes. The brilliancy of these crests 

 surpasses description, glistening as they do with the hues of polished 

 gold and red copper, changing into the gcmmy tints of the ruby and 

 emerald, now fire-coloured, anon the purest green, and presently the 

 brightest yellow. The scaly feathers of the forehead between the 

 two crests sparkle with metallic uniform green, changing to steel or 

 sapphire blue. A camail of dark changeable violet ext nds from the 

 throat behind the eyes, and descends along the sides of the neck to 

 terminate in a point of long feathers before the breast. This uncertain 

 violet graduating into a non-metallic blue, with its velvety very dark 

 tint, U sharply defined on the milk-white of the breast, which extends 

 to the lower part of the neck, so as to form a rather largo white 

 collar. The lower part of the belly is white; but the middle of the 

 abdomen and the flanks are, like the back, golden-green, with which 

 is mingled a little of the grayish colour of the base of the feathers. 



Back and sides of the head behind, back, and feathers of the rump, 

 metallic golden-green. Quills brown. Tail graduated, composed of 

 four feathers longer than the six others ; the two middle ones are 

 brown, the two external pure white. The other shorter external tail- 

 feathers are white, but their outer border is variegated with brown. 

 The tail below is white, slightly smoked as it were. The wings reach 

 only to the half of the tail, the general form of which is long, acumi- 

 nated, and narrow. Length 4 inches 5 or 6 lines. Bill 6.^ lines.
