stronger and rather large ; claws moderately arched, extremely com- 

 pressed, laterally grooved, acute. 



Plumage soft and blended, with little gloss ; wings of moderate 

 length, somewhat concave ; the second, third, and fourth primaries 

 having the outer web cut out toward the end ; the second quill is long- 

 est, the third scarcely a quarter of the twelfth of an inch shorter, the 

 foiu"th half a twelfth shorter than the third, and a quarter of a twelfth 

 shorter than the first ; the other primaries slowly graduated, the long- 

 est or second being only eight and a half twelfths longer than the first 

 secondary. All the quills, primary as well as secondary, are rounded ; 

 and there are only nine primaries. Tail rather long, considerably 

 rounded, the lateral feathers a quarter of an inch shorter than the mid- 

 dle, which are longest ; all the feathers rather narrow and obliquely 

 pointed. 



Upper mandible brownish-black, its edges in their whole length 

 pale yellowish flesh-colour, as is the lower mandible, which, however, 

 is a little dusky at the end. Iris hazel. Feet and claws flesh-coloured. 

 The upper part of the head, the hind part and sides of the neck, are 

 deep ash-grey, tinged with blue ; the back, scapulars, and rump deep 

 olive-green ; the wings and tail greyish-brown, the edge of the wing 

 and the outer margin of the first quill bright yellow, the other pri- 

 maries narrowly edged with greenish-yellow, the secondaries of a paler 

 brown externally, as are the tail-feathers. From the ridge of the 

 upper mandible to the eye is a rather broad band of black, which ex- 

 tends a little way under the eye, but is not nearly so conspicuous as 

 that of the species above described ; nor are the eyelids marked with 

 white, their marginal feathers being all dusky grey. The fore part of 

 the neck and a portion of the breast, to the distance of an inch and 

 five-twelfths from the bill, are deep black, with lunulate white mark- 

 ings, each feather being margined with that colour ; the white edges 

 of the lower black feathers being extremely narrow leave a crescent of 

 nearly pure black ; the breast, abdomen, lower tail-coverts, and lower 

 wing-coverts are bright yellow, the sides of the body yellowish-green.
