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 Male. — Is 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 Imeatus. 



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.
