JAVAN JUNGLEFOWL 265 
Cuick In Down.—Upper parts from crown to tail, and the wing down, dark 
chocolate-brown ; head, side neck and breast, brownish; line from lores through eye and 
ear-coverts back to the nape chocolate or black. A creamy buff line on either side of the 
dorsal brown along the sides and rump, bounded outside by a black line. Under parts 
creamy white. Iris pale hazel. Bill, legs and feet pinkish white or light horn colour. 
The difficulties under which one has to work in the study of such an important 
member of the Javan fauna as the Junglefowl, even in its native land, is well shown by 
the specimens in the Buitenzorg Museum. There were six males all told, very badly 
mounted, two adult birds, one nearly so, and three immature cocks. No females, chicks, 
or birds in juvenile plumage. Of the three young birds of equal age, one had yellow 
glass eyes, another jet-black beads, and the third rich hazel irides. The combs were 
enclosed or replaced with thin wooden pointed sheaths. If such diversity, due to lack 
of definite observation, exists here in the very haunts of this insular species, we, thirteen 
thousand miles away, can readily understand the total lack of accurate details up to the 
present time. 
JUVENILE PLumacE.—The sexes in this plumage are almost indistinguishable, 
judging from the small series I was able to collect. The cocks are more heavily pig- 
mented with black, the general type of pattern and colouring being, however, much like 
the adult female. The feathering on the face is already scanty, and, together with the 
chin and throat, is pure white. The feathers of the top of the head, neck, and upper 
mantle are all normally rounded in shape, and in colour predominantly black, with a 
rufous-buff fringe and a narrow shaft-stripe. On the lower mantle, back, and rump this 
shaft-stripe widens and becomes a conspicuous buffy-white. 
The lesser coverts are like the upper mantle, and the median like the back with the 
addition of a broad, transverse band and wide tip of buff or whitish. ‘The secondaries 
and their coverts are banded or spotted with whitish and rufous on the outer webs, as in 
the adult female. The primaries are plain brown. The tail-feathers are dark-brown, 
irregularly barred or edged with buff. 
The white feathers of the throat extend well down on the neck in a \V-shape, 
covering the area which in the adult is bare and occupied by the median wattle. The 
ventral plumage is reddish-brown, mottled and spotted with black. On the flanks are 
found faint traces of the sub-terminal concentric band which characterizes the adult 
female. The under tail-coverts are black, with a fringe of buff. 
The iris is pale hazel, and the spurs and comb are rudimentary. The facial skin as 
seen through the feathering is flesh colour, and the legs and feet are pinkish. 
First ANNUAL OR PosT-JUVENILE Mou tt.—In all the specimens which I have 
seen, this moult leaves the bird in a very imperfectly adult plumage, and it is probable 
that not until the second annual moult does the Javan Junglefowl ever come into its 
fully adult dress. 
The typical change is as follows, although no two specimens are exactly alike, and 
indeed this is the most variable period of the bird’s life as regards its external characters. 
The brown head, neck, and mantle feathers are replaced with black ones, with a slight
