HOUWINK’S EXPER. CONC. THE ORIGIN OF SOME DOMESTIC ANIMALS 245 
comb; it is otherwise very much like a-bankiva, the cinnamon of the 
breast has hardly any black, white shaftstripes are very conspicuous 
on the back, the secondaries are faintly pencilled, the iris is of a dark 
gold colour. 
276.5 Pis a 4 month’s old chick, still showing the primary plumage 
(Pl. VI fig. 1) with its very distinct crossbars, it has sonneratian sub- 
marginal stripes on the latteral feathers of the breast and bankivian 
cinnamon on the throat. 
276.8 2 (Photo Pl. IX fig. 5)isa buff-colored or wheaten-colored ani- 
mal with a very light, almost white, breast and belly, a dark black and 
brown mottled tail and considerable submarginal black near the tips of 
the neckfeathers, and also on the lower half of the tailcoverts, while the 
secondaries are vermiculated with black. This hen is still living. 
276.9 2, became broody in 1922 after having laid three eggs, Pl. VI 
fig. 2 and Pl. IX fig. 2 give a picture of this hen. It looks very much like 
a partridge colored bantam, and has barred secondaries. The wide cen- 
tral stripe of the feathers of the back, near the neck, may be due to 
Sonnerat. 
276.12 2 has not been broody in 1922, laid 16 eggs from which no 
chickens were raised; in that year the care of the animals was however 
insufficient. It is, as the photos’ Pl. IX fig. 4 and Pl. VI fig. 3show, a 
beautiful little animal with a black tail and green legs. It is characte- 
rised by the very distinct light margins around the feathers of the back 
and breast, and by the barring of the wingfeathers; the colour of the 
neckfeathers is silvery. 
276.13 © (Pl. IX fig. 3 and Pl. VI fig. 4) has been broody in 1922, and 
‘aid 4 eggs from which no chickens were raised either; it is all over a 
little darker than the former, but, like it, approaches the pencilled type 
of our domestic poultry. Both 276.12 and 13 have the ventral surface 
very much of the same pattern as the back. This hen has yellowish 
green legs, green ear wattles and the tail chiefly black, while the wing- 
feathers are still more distinctly barred than in the case of 276.12; the 
neckfeathers are more straw-colored. 
276.14 9 (Pl. VI fig. 5) was not used in the breeding-season 1922, it is 
a peculiarly colored animal, the neck, the ends of the wing and the 
tail being dark, while the rest of the body is pale, so that it looks as if 
it were a black animal, partly covered by a pale sheet. A similar kind 
of bird we got from our inbred bankantams, (to wit: 428.3) so that it
