AVES ANATID>E. 491 



Tail : The pointed feathers are graded in length to the longer central 

 ones, which curve upward ; they are deep slate-gray from above and paler 

 when seen from beneath. 



Wings : There is a single wing-tubercle on each wing, a third of an 

 inch long and pale yellow in coloring. The scapulars like the mantle in 

 color and marking, the longer ones being glossed slightly with olive; pri- 

 maries deep dusky slate ; secondaries pure white ; tertials like the longer 

 scapulars; wing-coverts immaculate slate-gray, the greater series tipped 

 with pure white ; the marginal under wing-coverts are slate-gray ; the rest 

 of the under wing-coverts and axillaries pure white. 



Lower parts : Chest and breast dark slate-gray, each feather with a sub- 

 apical band of dusky slate, giving to the whole a scaled appearance ; sides 

 like the breast, the longer feathers of the flanks washed with olive ; abdo- 

 men and under tail-coverts pure white, the change from the slate of the 

 sides and breast being abrupt and defined. 



Bill : Horn-color, shaded with blue and green, the nail abruptly black. 



Tafkyrres cinerrus. P. U. O. C. 8847. Adult male. Foot from in front, 

 showing the webs. Reduced. 



Feet: The feet and legs are dull greenish brown, strongly shaded with 

 orange. 



Iris: Hazel-brown. 



This adult male bird, it will be seen, has different coloring on the bill 

 from that generally described ; the bird has nearly completed the moult 

 directly after the breeding season and it is at least two if not three years 

 old, probably more.
