HOUWINK S EXPER. CONC. THE ORIGIN OF SOME DOMESTIC ANIMALS 255 
tips. The shoulder coverts are black, some with a sonneratian white 
shaft stripe. The throat is black; there is a broad, rather pale brown, 
sonneratian belt, while the belly is nearly black. 
The legs are yellowish green with very distinct red sonneratian 
longitudinal stripes. 
391.15 3 (Pl. IX fig. 10) is still alive, It has the comb broadened in 
front so that it almost resembles a rosecomb with a median ridge at 
that point, further backwards the comb is an ordinary single one with 
6 teeth and an endpiece. The whole comb is rather warty, and it, like 
the gular and earwattles, red; 177s almost white, with a little goldcolour 
at the outer periphery. Dorsally, the pattern is that of bankiva, the 
hackles, with the exception of the lowest ones, are deprived of a black 
median stripe e. g. bankivian. Shoulder coverts black with a white 
sonneratian shaftstripe. Secondaries brown at the outer, black at the 
inner side; most of the primaries with a little brown at the outer side. 
Tail and tailcoverts green. 
Ventral surfface buff, except on the sides of the throat, where there 
is some black. Legs lead-blue. 
391.16a 3; of this bird we have only a feather chart, which shows 
that it must have been very much like 391.7a & (now 391.18 4). 
391.17 & is still alive; proximally the comb has 3 small teeth, follo- 
wed by 4 larger ones and a distal smooth piece. Comb and gular-, as 
well as earwattles are red; bill of a dark horn colour. Dorsally the ani- 
mal is almost a bankiva with hardly any black in the hackles, but with 
something sonneratian in the white shaftstripe of the shoulder-coverts. 
Tail and tail-coverts are blue green. Most of the primaries have a little 
white at the outer margin ; secondaries brown at the outer side, but tips 
black. 
Ventrally the throat has some black laterally, but the rest of it, as 
well as the breast and the belt, are of a dark buff color ; the belly is black 
mottled with brown. Legs willowy with distinct red sonneratian, lon- 
gitudinal, stripes. 
604.2 & is a young bird; part of the plumage is still juvenile and 
cross-barred; as far as can be judged, it was likely to have developed 
in to a very bankiva-like bird; the lower surface is rather dark, almost 
black, the legs are very dark too. 
604.3 3, somewhat older than the former, looks very much like a 
bankiva, and is ventrally almost pure black, its legs are very dark also.
