232 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
observation that Sonnerat itself is a sedentary bird, which, when let 
loose in Italy, remains near home. 
GHIGI thinks that man has been able to domesticate sedentary birds 
only, not birds with an erratic instinct, and that this is the reason why 
pheasants have never become completely domesticated. 
If this opinion holds good, and it looks very probable that it will, 
we must assume that bankiva also is a sedentary bird — and the fact, 
which the senior author observed in Java, that one is always sure 
to meet with wild bankiva’s at any spot where one has previously seen 
them, speaks strongly in favor of this — and that it is owing to this 
sedentary habit that bankiva could take so big a share in the building 
up of the domestic poultry. If this is really so, it is of course impro- 
bable that wild bankiva’s have seriously become infected with the 
blood of domestic poultry, as BEEBE assumes, because the hybrids will 
have stayed, „at home”. If it should prove that Gallus lafayetti is not 
a sedentary but on erratic species and this looks very probable, if the 
account that hybrids of it with domestic poultry go to the jungle be 
correct, this would also account for the fact, that this species has not 
been tamed and therefore taken none or but little part in the building 
up of domestic poultry, although it may have had part in the formation 
of the yellow legs of some domestic races. That Sonnerati, evidently a 
sedentary species, has not been tamed is curious, one might probably 
do it still, even in Europe, judging by GHIGT’S account. 
As to Mr. Houwink’s crosses with Sonnerati, MR. DE Bas of the 
Hague presented a fine pair of Sonnerati: a cock 195.1 and a hen 195.2. 
The hen died soon, without having had any progeny. The cock was 
mated to the bankantam-hen 201.3, a daughter of the original pair, 
and died at the end of the first breeding-season ; so that of this pair only 
three hybrids were obtained, e. g. one cock 198.1 g and two hens 198.2 
2 and 198.3 ©. 
The Sonnerat-cock 195.1 and the Sonnerat-hen 195.2 are pictured on 
Pl. V Genetica Vol. V p. 175. Of the F, cock 198.1 4, we, unfortunately, 
can give but a part — photograph Fig. 1 and 2 Pl. IV, because this ani- 
mal was killed in 1920 by a Putorius putorius, which ate both neck 
and head, as well as one of the feet. This is greatly to be regretted as we 
all took pride in the beauty of this hybrid, the only one obtained which 
plainly showed the waxy spots on the hackles, although these were greatly 
reduced. It is a great pity that this bird was not drawn before its un-
