440 ULULA ALUCO. 



The plumage is very full, elastic, and extremely soft. The 

 facial disks are complete, though narrower above the eyes. The 

 ruff also is complete, extending from the base of the upper 

 mandible to the throat, and composed of narrow recurved fea- 

 thers. The feathers in general are oblong, with their downy 

 part greatly extended, those on the upper parts somewhat com- 

 pact, on the lower almost downy ; on the tarsi and toes very 

 soft and blended. The wings are long, very broad, much 

 rounded ; the outer six quills a little sinuate on the outer and 

 inner webs ; the barbs of the outer web of the first, and the 

 sinuate portion of the second and third, free and recurved ; the 

 first two inches shorter than the second, which is one inch 

 shorter than the third, the fourth a quarter of an inch longer 

 than the latter, and slightly exceeding the fifth ; the secon- 

 daries thirteen, very broad and rounded. The tail is of mode-

 an inch shorter than those in the middle. 



The bill is pale greyish-yellow, the cere flesh-coloured. The 

 iris bluish-black. The soles of the feet are flesh-coloured, the 

 claws greyish-yellow at the base, dusky toward the end. The 

 inside of the mouth is light flesh-coloured, excepting the ante-

 The general colour of the upper parts is light yellowish-red, 

 longitudinally streaked, mottled, and transversely undulated 

 with dark brown ; the hind part of the back mottled and barred, 

 with the streaks reduced to lines. Some of the outer scapulars,

 large white spot on the outer web toward the end. The quills 

 are broadly barred with umber brown and dull light yellowish- 

 red tinged with grey ; the primary coverts darker, but similarly 

 barred. The tail-feathers, except the two middle, which are 

 like the hind part of the back, are marked like the quills, and 

 tipped with yellowish-white. But both they and the quills 

 are finely barred or mottled with brown, especially toward the 

 end. The facial disks are greyish- white, the anterior with 

 black shafts, those behind tinged with yellowish-brown. The
