ceased or been turned into another channel, while the juvenile colours again flowed and 
functioned. 
In following the development from chick to adult, confining ourselves always to 
corresponding centres of plumage, we find two paths of pigment evolution: first, sandy- 
brown, red-brown, dark-brown, black, and iridescent green; and second, whitish-buff, 
pale straw, yellowish, orange-yellow, orange and deep orange-red. This is well illus- 
trated by the inner secondaries, which, in the retention of juvenile characters (permanently 
in the female, and longer than any other area in the developing cock) are the most 
generalized feathers of the plumage. They are mottled and barred with sandy-brown 
and whitish-buff. If we proceed from them mantlewards, we find them leading through 
feathers with more and more black until this culminates in the extreme of green 
iridescence. Covertwards, the pale edges increase and change through the yellows to a 
rich orange-red. 
HYBRIDS 
I have given what data I could in regard to the origin and uses of the bekisars or 
hybrid cocks between the wild Junglecock and domestic hen. In coloration there are 
two general types, derived through the mother from the red and the cream-coloured 
Malay game. These two colours are always most apparent and the last to disappear on 
the wing-coverts. The extreme of the red type is where the violet and green iridescence 
have spread over the body until they almost or quite obliterate all other pigments. 
I secured a young cock in which the red is reduced to narrow fringes on the coverts 
and rump. The bill, face, feet, and legs, and most of the comb and wattle are jet black. 
The extreme of the cream type is pure white throughout. I have a poor specimen, 
which is whitish in general, with golden-yellow fringe on the hackles, but dirty cream 
on the coverts and back, with the wings and tail part white, part metallic green. 
The neck hackles of the first generation hybrids are much like those of varius, but 
with narrow margins of buff or red. The sub-auricular flaps or wattles are often of large 
size. The green area on the comb is usually replaced with the red, and the yellow 
on the wattle with bluish white. In pure white birds this area may be sulphur-yellow. 
The irides of all are pale, but orange instead of yellow. The shape and colour of the 
comb are like those of the domestic cock, while the median wattle is as in varius. After 
death, however, the basal part of the comb, which is greenish in vavzus, at once turns 
fleshy white, while the remainder holds its deep red hue for many days before slightly 
fading. Occasionally a bird will be found with both comb and wattle as in varius, and 
exaggerated both in size and colour. The rarity of such types of birds is attested by 
the high price at which they are held. 
The general character of the crow and the power of flight are both like those in the 
wild fowl. In general size the hybrids excel both parents. 
The second generation are known in many places as #ekoks. This is probably 
a contraction of dekékko, a name which in Western Java is given to the wild red 
junglefowl. The aptness is apparent when we see that in the majority of these kekoks 
the plumage reverts to the gallus type. The hackles become long and lose much or 
all of the violet. While the median wattle may be well developed in life, its two 
dermal walls are attached so loosely that after death it splits, and the throat shows
