The F, generation 
While we have been able to inbreed the Bankantams, we have not 
been able to inbreed the Sonnerat’s, so that we dot no know whether 
they would have shown deviations from the type. The two Sonnerat- 
cocks used in the experiments: 195.1 4 and 269.1 3, as now stuffed, 
differ considerably, but this is due to 195.1 3 having died in full-plu- 
mage, 269.1 in eclipse plumage e. g. when the characteristic hackles 
with their waxy-spots were shed. Different authors do not agree as to the 
character of Sonnerat in nature; there certainly seem to be differences 
between the wild birds admitted to this group, but while some think 
that at different altitudes, different races exist, BEEBE considers all of 
them to be mere modifications. Without breeding-experiments it is of 
course impossible to decide who is right. As to the crossing of Sonnerat 
with native domestic poultry, all authors whom we have been able to 
consult, agree to its occurring, but differ as to the frequency of it, some 
considering it as quite common, others as extremely rare. We have been 
unable to find any account of wild hybrids between bankiva and Sonne- 
rat, notwithstanding both species occur in the same general region in 
British India, but this of course does not prove that no such hybridsexist. 
It is an interesting fact, that BEEBE states, that in the native villages 
hybrids of the native domestic poultry with Sonnerat are frequently 
seen, and that such are readily recognized bij the waxy spots on their 
hackles, interesting because this shows, that the hybrids with Sonnerat 
do not run away to the Jungle — as is reported of the hybrids between 
domestic poultry and Lafayetti. This is in full agreement with GHIGI’s
