Cyclorliis flavipectus. 



Cyclor-his flavipectus, Solatek, P. Z. S. 1858, 448 (Trinidad and Santa 

 Martha).— Ib. Catal. 1861, 45, no. 275. — Taylok, Ibis, 1864, 81 

 (Trinidad). 



Hah. Trinidad and northern coast of South America. 



(No. 32,719, %.) Head above, and nape, light plumbeous, washed very 

 faintly with orange or oohrey brown ; cheeks paler, and pure ashy, running 

 iuto the still lighter, almost white chin ; rest of upper parts bright olive 

 green. Throat and breast (extending down a little more along the sides) 

 bright greenish-yellow ; the inner face of wings and inner edges of quills 

 purer yellow. Rest of under parts white. Under surface of tail decided 

 olive green. A broad superciliary band of orange or ochrey brown from 

 nostrils (the two meeting on the forehead) reaching to the nape, rather farther 

 beyond the eye than the distance to it. Bill horn color, the tip and edges 

 whitish ; the lower mandible plixmbeous black. Legs flesh color. 



Fourth and 5th quills equal and longest ; 2d shorter than the 10th and the 

 secondaries. 



(No. 32,719, %.) Total length, 6.00; wing, 2.80; tail, 2.60; exposed por- 

 tion of 1st primary, 1.05, of 2d, 1.75, of longest (measured from exposed base 

 of 1st primary), 2.16; length of bill from forehead, .75, from nostril, .46, 

 along gape, .83, depth, .36 ; tarsus, .88 ; middle toe and claw, .72, claw alone, 

 .30 ; hind toe and claw, .61, claw alone, .34. 



The extreme nape is of a purer plumbeous than elsewhere on top 

 of the head. No, 32,719 has a faint buff wash on the sides of body- 

 not seen in the others, and probably indicative of the autumnal 

 plumage. * 



This species is readily distinguished from G. guianensis, which it 

 otherwise resembles, by the yellow, not dusky legs : the greater 

 amount of yellow beneath, which extends over the jugulum to fore 

 part of breast: and the ochrey wash of top of head, although this 

 latter character may depend somewhat on season. The ash of 

 cheeks and chin is lighter, the yellow of under parts purer. The 

 size is larger, the bill deeper ; the legs stouter, besides being differ- 

 ently colored. There is less of the gray tinge of the under parts 

 of guianensis.
