The eyelids are fringed with short feathers having disunited 

 filaments. The ruff extends from a little above the ear to the 

 chin, and is formed of oblong, slightly curved feathers. Over 

 and above the eye, on each side is a double series of elongated 

 feathers, of which there are nine in each row, the longest pro- 

 jecting upwards of two inches beyond the rest of the plumage. 

 On the upper parts, the feathers are oblong and rounded ; on 

 the throat downy, on the fore-neck ovato-oblong, on the upper 

 part and sides of the thorax elongated, oblong, rather pointed, 

 and covering those of the thorax and abdomen, which are 

 downy. On the outer side of the tibia is a tuft of very soft 

 elongated feathers ; and the tibiae, tarsi, and toes are covered 

 with soft blended feathers. The wings are long, of great breadth, 

 and rounded ; the quills twenty-seven ; the primaries very 

 broad, the first four cut out on the inner web near the end, the 

 outer two only having an abrupt sinus ; the second, third, and 

 fourth with the outer web slightly narrowed; the first with the 

 barbs of the outer web free and recurved at their extremity in 

 its whole length, the second and third toward the end. The 

 first quill is an inch and a half shorter than the second, the 

 third longest, exceeding the second by two twelfths, and the 

 fourth by one twelfth. The tail is broad, arched, rounded, the 

 lateral feathers being an inch shorter than the longest. 



The bill is greyish-blue at the base, bluish-black toward the 

 end ; the cere dusky ; the soft edges of the mandibles flesh- 

 coloured, as is the inside of the mouth. The iris is bright 

 orange ; the bare edges of the eyelids and the margin of the 

 nictitant membrane dusky. The scutella are pale greyish- 

 blue, the claws of the same colour as the bill ; the soles pale 

 flesh colour. 



The facial disks are pale yellowish-brown, faintly barred 

 with dusky ; their anterior part greyish-white, with the shafts 

 black at the end. The feathers of the lower eyelid are greyish- 

 white, of the upper chiefly black. Those over the eye, and the 

 long tufts, are brownish-black, internally edged or mottled with 

 reddish. The general colour of the upper parts is reddish-yel- 

 low, spotted, barred, and minutely dotted with dark brown. 

 On the lower part of the hind-neck, most of the feathers have
