c. atype, which if it had reached adult age, would have developped 
a collar very much like that of Temminckii, but which differs 
from it by the presence of a serrated comb. A few juvenile 
feathers left on the specimen show the type of barring of the 
feathers of the varius hen 211.15 (Pl. VIII). 
The two birds which have not been stuffed 211.7 gand 211.14 ¢be-

The experiment shows clearly that hybrids of bankantam’s and varius 
segregate. 
Of the females of this generation, we have before us:

Here also a decided segregation is seen; the two birds 211.4and 211.6 
are lighter and in the general pattern of the feathers more bankiva like, 
especially the former, which shows but very little cressbarring on the 
chiefly mottled secondaries, while the two latter 211.11 and 211.13 are 
much darker and varius-lke, especially the latter; with very distinct 
crossbars on the secondaries. There can consequently be no doubt, that 
bankantam-varius hybrids segregate, 
The F, Generation of Gallus Temmincku 
Of this generation but three adult animals, to wit 2 cocks 218.1 4 and 
218.2 & and one hen are available. All three are chiefly bankivian and 
in all three the varius influence is chiefly visible on the ventral surface, 
this being pure black in the case of the cocks, while as we saw our 
bankantams were mottled with brown; and pale in the case of the hen, 
moreover the secondaries of the hen are crossbarred in the typical 
varius-fashion.
