Habit/Jit. — Chachapoyas, Peru. 



Male. — Crown of the head brilliant blue, neck scapularies, 

 back wing and tail-coverts golden-green ; on the throat a gorget 

 of very brilliant green tinged with blue in the centre, and 

 bounded on each side by a narrow band of coppery red ; sides 

 of the breast and abdomen white ; flanks golden-green. Median 

 and lateral rectrices very short, dark green ; outermost ones very 

 long about three times the length of the body, very narrow 

 until near the end where they terminate suddenly with a broad 

 spatule of a dark blue colour crossed with darker lines, very 

 distinct in certain lights. The spatules are as broad as long, 

 wider in the middle and curved in half a circle, in nearly all 

 their length, so that in their natural position they cross twice 

 one another. Undertail-coverts green margined with white. 

 They are in general long, but the two posteriors are very long, 

 more so than the body, and pointed. These are dark bronzy- 

 green on their basal half passing to dark blue with tips whitish ; 

 bill and feet black. 



Total length, 147 mill. Wing, 40. Tail, 125. Culmen, 21. 

 Posterior undertail-coverts, 80. Width of spatule, 30. 



Female. — Upperside less golden than the male. Head 

 grayish-bronze. Underside white washed with dove color, 

 throat spotted with green, flanks and abdomen golden-green. 

 Median rectrices brilliant green, lateral green at base passing to 

 bluish-black at tips ; outermost grayish passing to blue on 

 spatula, which is oblong. Undertail-coverts dove colour, the 

 posterior ones reach three-fourths of the outermost rectrices, 

 and are pure white.
