(No. 10,211.) Above olive-green, rather brighter on the rump ; beneath, 

 including lining of wings, bright golden yellow. Entire head all round, with 

 broad streaks on the breast aud sides, orange-brown. Wings nearly black, the 

 larger coverts, first primary, alula, and inner secondaries broadly edged with 

 greenisli-yellow ; the other quills with olivaceous like the back; the insides 

 of the quills broadly and sharply margined obliquely with yellow, which 

 reaches the shaft on the inner secondaries, and in all the quills except the 

 long primaries, is continued entirely around so as to join the exterior margin- 

 ing. Exposed surface of the Tail feathers (including their outer webs) dark 

 greeni.sh-brown, edged externally witli the color of the back, the outer feather 

 alone having the outer web yellow, with a dark shaft streak from near the 

 base. The inner webs of the 1st, 2d, and 8d feathers entirely yellow, except 

 at the end ; the 4th and 5th with more aud more dusky along the shaft ; the 

 6th with narrow margin only of yellow. Bill dark liorn color. Legs pale. 



The colors of the female are much duller ; the head only tinged with brown, 

 especially along the centres of the feathers, and the streaks on the body be- 

 neath, indistinct. The inner webs of the tail feathers show much more browu 

 on them. 



The wings, in this species, are broad and rounded, as in petechia. The 3d 

 quill is longest ; the 4th and then the 2d a little shorter; the 1st about inter- 

 mediate between the 2d and 5th, not shorter than the 5th. The tail is con- 

 siderably rounded. In five specimens tlie formula is 3. 4. 2. 1. 5. <5 ; in one, 

 3. 2. 4. 1. 5. 6. The difference between the 1st and 3d quills is about .19. 



Total length, 5.00; wing, 2.75; tail, 2.30; width of outer feather, .35; 

 difference between 1st and 3d quills, .13; length of bill along culmen, .50, 

 from nostril, .35, along gape, .63 ; tarsus, .81 ; middle toe and claw, .62; hind 

 toe and claw, .50. 



This species, in the broad rounded wings, short first primary, and 

 wide quill- and tail feathers agrees with petechia much more than 

 with sestiua, although it is even larger, and the wings proportionally 

 longer (including 1st quill) than petechia. The 1st quill, too, is
