262 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
about 3 months old, as this death, in connection with the death of the 
varius-cock, made the obtention of an F, impossible. 
This F, hen shows strongly crossbarred juvenile plumage, very simi- 
lar to tat of a number of chicks obtained by inbreeding the original 
bankantams. The cock 196.3 4 evidently died at a somewhat later age, 
as it shows already signs of adult plumage cropping up on some parts of 
the body. He has a comb with delicate teeth and also crossbars on the 
juvenile plumage still present. As the F, cock which became adult 
(196.2 3) and which, by the bye, in 1924 at an age of 9 years, is still fer- 
tile, has a comb almost without teeth, very like the one of varius, this dif- 
ference between the brothers caused at first some surprise, as we imagin- 
ed that varıus-cocks always had smooth combs, but we learn from Beebe 
(quoted Genetica V p. 45) that perhaps 10% of wild varius cocks show 
very faint serrations on the posterior half of the comb and that he even 
once found five well marked teeth, near the posterior angle of the comb 
ona wild shot bird, one of these teeth was even double-notched. 
Of the only cock which reached adult age, 196.2 3, a most beautiful 
animal, compare colored pl. III fig. 196.2 and pl. VIII, which, as was 
stated is stillalive, the authors made the following description in 1920 
Bill. Upper mandible black in the median line, horn color at the sides, 
lower mandible black at the base, otherwise horn-color. 
Comb. An almost rectangular triangle, fixed to the head by the longer 
side of the rectangle, the hypothenusa forming the upper border 
of the comb. The larger, anterior part of this border is entire, the 
posterior part shows faint traces of five small teeth. The top of the 
head, immediately behind the comb, is bald and red. 
The comb itself is indented laterally, so that it is almost mussel- 
shaped, its color is a blue-red. 
Face, darkred. 
Eye, Iris light yellow, with orange radii. 
Earlappets, rather large, red, in the center irregularly spotted with 
yellow-white. | 
Gular wattles, small, red, musselshaped. 
Median wattle, near the bill bluish red, further down yellowish white, 
the two colors passing into one another. 
Crown-feathers, narrow, darkredbrown, with a very narrow black tip. 
Eardeck, consists of blackbrown feathers. 
Collar, clearly differentiated into two parts. The upper part consists of
