water, sometimes choosing a cleft in rocks overhanging a moun- 
tain stream, sometimes a broad shelf in the clay cliffs of some 
a 
bright yellow. Iris very narrow, but of large diameter. Orbits, with a dense 
double row of bristly, black shafted, white feathers, with the bare shafts 
considerably elongated. ‘The rest of the eyelids bare; the upper greenish, 
the lower greyish brown. 
Cere greenish grey. Bill dingy greenish; point of the upper mandible 
blackish horny ; of the lower mandible yellowish. 
Plumage. Uoves with a huge patch of bristle-like white feathers with 
greatly elongated black bare shafts overhanging the commissure and meeting 
over the base of the cere; some of them almost if not quite as long as the 
bill itself. The whole of the forehead, top and back of the head are a some- 
what pale pinkish brown, each feather centred darker. The feathers above 
the ear coverts on each side, behind the eye, lengthened so as to form 
aigretttes or ear tufts from an inch and a half to two inches in length. The 
feathers of the back of the neck often a somewhat darker shade, more broadly 
shafted with a still darker brown, and most of the feathers with a trace of 
wavy mottling or obscure bars especially towards the tips on the lighter 
brown portion. Upper back and scapulars much the same hue, and dark 
centred in the same manner, as the feathers of the back of the neck, but most 
of the exterior feathers of the scapulars where they overhang the lesser wing 
coverts with nearly the whole outer webs white, and the lighter brown of the 
scapulars and ina less degree of the feathers of the upper back very much 
mottled and variegated with tiny wavy lines and small irregular blotches of 
fulvous white. Lower back, rump, and upper tail coverts much the same 
hue as the upper back, but with only a central line of dark brown and very 
feebly mottled with fulvous white. All the lesser wing coverts, the same 
brown as the upper back, with similar broad dark brown centres, with a few 
spots of fulvous white on some of the longest. The median coverts mostly dark 
brown towards the shafts and on the inner webs, with one or two well marked 
spots of white or fulvous white on the latter, and the outer webs mostly white 
or fulvous white, freckled or mottled with paler brown. The winglet and pri- 
mary coverts chiefly dark brown with two or more imperfect transverse bars 
of fulvous white or paler brown. The greater coverts of the secondaries much 
the same as the preceding, but the outer webs much tinged with pale fulvous 
brown, and there is more white and more mottling about them than the 
preceding. The primaries are dark brown tipped with fulvous white and 
with four or five + to 2 inch transverse bars, of white, fulvous or rufescent 
white, on the outer, and pale brown across the inner webs. ‘The secondaries 
have’ much the same character as the primaries, but the bars are closer and 
larger in proportion and are more conspicuously mottled, and as a whole 
generally appear to have more white upon them than the primaries. The 
tertiaries and their coverts like the greater coverts of the secondaries are a 
paler and more fulvous brown, much marked with imperfect bars or blotches 
of fulvous white mottled with brown. The tail feathers are dark, somewhat 
unber, brown tipped with rufous or fulvous white, and with three or four com- 
paratively narrow transverse bars of the same hue, most of the bars showing 
marks of faint mottling with a darker colour. Under the eyes and ear coverts, 
is a conspicuous patch of elongated, bristle-like rufous brown feathers with 
dark shafts ; on the point ofthe chin is a patch of white bristle-like feathers, 
with clongated bare black pointed shafts, which curl up round, and are nearly 
as long as the lower mandible. The feathers of the rest of the chin and a patch
