distal greater wing-coverts and coverts along margin of wing immacu- 
late white; distal secondaries pale gray, their inner webs white; four 
inner (proximal) primaries pale gray narrowly margined with white, 
the sixth (from outside) similar but with a blackish subterminal spot 
or blotch, the fifth (from outside) mostly pale gray with shaft dusky 
and distal portion (for about 30-35 mm.) black, the extreme tip 
white; fourth with the black much more extended (125 mm. or more 
on outer web), with a still smaller apical spot of white; third 
primary with outer web black almost to base of outer web, the second 
and first (outermost) with outer web entirely black; bill black, 
with terminal third (approximately) yellowish horn white, pale 
olive-buff or grayish pea green; rictus and broad tumid naked, 
orbital ring orange-red to deep red or crimson; skin of inter-ramal 
space salmon-red or pink; iris dark brown; legs and feet peach-

Young.— Head white, with pale brown streaks on the lores, 
and darker confluent markings in front of and round the eyes; a 
clove-brown patch on the auricular [region]; feathers of the neck 
and mantle broadly barred with ash to umber brown and tipped with 
white; the long inner secondaries with brown centers and with some 
gray on the outer webs; the outer secondaries and the wing upward 
to the carpal joint white; primaries as in the adult; rump gray 
mottled with brown; tail-feathers white, broadly banded with 
brown (except the outer pair, which have merely brown tips), and 
all of them edged with white; under parts white; bill blackish, the 
lower mandible dark horn color; iris brown; tarsi and toes clay-brown 
(probably flesh-color in the living bird.’’) ¢ 
2 The three outer primaries have the white apical spots reduced to mere specks 
which would undoubtedly quite disappear with slight wearing of the feathers.

be some variation in the colors of the feet, etc., Mr. C. F. Adams’ description from 
freshly killed specimens being as follows: 
Adult male.—Tip of beak pearl gray; basal portion brownish slate-black; itis seal 
brown (large pupil); eyelids coral red; tibize just below feathers washed with vermilion, 
most intense next feathers, and between toes at base of webs about same color; tarsi 
and toes rose pink; creases in webs dusky, the papillae rose pink; nails brownish 
black, with a narrow grayish line on top; under surface of webs same color as upper; 
under surface of toes and heel orange-ochraceous (not showing on heel when foot is” 
resting on flat surface); between scales on tarsi light ashy; webs most dusky at edges. 
Length, 224; extent, 4 feet 44 inches.
