plete in all cases; the nearest approach to typical Mendelian 
inheritance is exhibited in the crest, but in the first generation it 
is always reduced. The white color of the crest is recessive in 
the male hybrids, but is not entirely absent in the females. The 
high nostril is recessive, yet it shows its influence in the first hy- 
brids. The comb in the first hybrids is different from that of 
either parent, yet in the second generation there is a partial 
return to the two parent types. 
An interesting cross was made between the Japanese long- 
tailed fowl or Tosa fowl (Fig. 12; 2) and the white Cochin Ban- 
tam (Fig. 12;1). In the Tosa fowl the feathers of the tail show 
continuous growth, reaching in extreme cases 18 feet, and 
generally 7 to 8 feet. 
There is a marked sexual difference in the Tosa breed, but not 
in the white Cochin. The male hybrids had the coloration of the 
Tosa cock except that every feather was barred with white 
(Fig.12; 3). Thefemalehybrids were like the Tosa hen, excepting 
that the shafting was much broadened, and the saddle feathers 
and the secondaries were black and buff barred. In the second 
generation the two original types reappeared. There were 28.1 
per cent white (Fig. 12: 4) and 71.9 percent pigmented individuals. 
However, of the whites, only five were without reddish pigment, 
showing that they were contaminated by the cross. ‘The 41 pig- 
mented individuals showed a curiously mixed lot of coloration. Of 
41 mature females 6 are like the female Tosa fowl, without barring, 
but sometimes with wider shafting than the male Tosa fowl. 
The remainder have feathers of the back and wing coverts barred 
with lighter, even with white —a condition not found in the female 
first hybrids. One of these shows a mixture of female Tosa 
and female Partridge Cochin coloration. Asno Partridge Cochin 
is involved in the immediate ancestry, this looks like a ‘rever- 
sion’; the characteristic has probably lain latent in the White 
Cochin. Of 10 males, 2 showed no trace of white, and may 
consequently be considered as homozygous. The remainder are 
more or less barred with white. One bird shows a remarkable 
mixture of Tosa and male Partridge Cochin coloration.” The
