HAINAN SILVER KALEEGE 75 
rump, but with the shaft-streaks paler and larger, dying out on the longest coverts 
and inner secondaries; secondaries show coarser mottling, and are very dark on the 
inner web, which in the primaries is plain brownish black. Central rectrices rufous, 
vermiculated with black. Lateral rectices chestnut, almost free from dark mottling. 
Chin and throat white, changing abruptly to the mantle pattern, although the white 
is so predominant that I should invert the description of the pattern, and say that the 
ventral surface was white with very wide black margins; on the side neck this merges 
insensibly into the mantle; on the sides and under tail-coverts the black increases in 
_ width. 
Iris light brown ; upper mandible greenish brown, lower dull green; naked skin on 
face red; legs and feet bright scarlet. Length, 520 mm.; wing, 205; tail, 228; tarsus, 
76; middle toe and claw, 53 mm. . 
First YEAR PLuMAGE Mare.—lIs similar to the female, except that the crest of 
steel-blue is just making its appearance, and the black of the mantle and hind neck is 
replaced with olive; the body plumage as a whole is darker, and more rufous, while the 
central rectrices are chestnut, like the lateral ones, and faintly marked with numerous 
fine, wavy, oblique bars. The secondaries are similar to the central rectrices. 
This, I think, unquestionably shows the derivation of the species from some more 
finely marked mainland form in the direction of /zxeatus. 
The chin and throat are black, with broad tips and a shaft-streak of white, and the 
ventral surface shows a greater amount of black than do the females. Wing, 230 mm.; 
tail, 258; tarsus, 86; middle toe and claw, 60; spur, 8 mm.
