234 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
the waxy spots. The whole Sonnerat-belt of the hybrid however is 
much more conspicuously brown than that of Sonnerat, and even the 
breast of the hybrid has some brown. The outer margin of the breast- 
feathers of Sonnerat is white, while it is yellowish to brown in the case 
of the hybrid. This bankivian influence is also apparent in the much more 
intense black of the , black” part of those feathers, this „black’’ being 
no genuine black, but a dark gray, in the case of Sonnerat. A note, made 
during a visit to Mr. BLAAUW at ’s Graveland, says that our hybrid 
has a marking.of the breast of a similar type as that of Mr. BLAAuw’s 
hybrid between a female black Bantam and a Sonnerat-cock and that 
the waxy spots on the wingcoverts of the two hybrids also are similar. 
At that time, our cock already had lost its head but my recollection 
is, that the waxy spots on the hackles of Mr. BLAAuw’s hybrid were 
more distinct than those of our cock. . | 
‚Mr. Braauw’s hybrid has the red shankstripes characteristic. of 
Sonnerat; whether these were present in the case of our hybrid or not, 
we are unable to say, judging from their presence however, on other, 
less Sonnerat-like, hybrids in Mr. HoUWINk’s experiments we feel con- 
fident that they were. 
On the dorsal side, the influence of the bankantam-mother is appa- 
rent in the yellowish to brown color of the margin of the feathers, 
which are white in Sonnerat. The influence of Sonnerat is shown in the 
white median stripe of the dorsal feathers and especially in the bluish 
colour of the central part of the saddlefeathers, which in shape are some- 
what intermediate between those of bankiva and Sonnerat, with a de- 
cided leaning towards bankiva. The bankiva-influence is again very 
strong in the green color of the upper tailcoverts, while the lower tail- 
coverts are violet with a touch of green, differing from the decidedly 
bluish violet of the tailcoverts of Sonnerat. The large tailfeathers are 
very much broader than either those of Sonnerat or of Bankiva, while 
they have a dark violet shine, differing from the almost undefinable 
„blue with a trace of green” of Sonnerat. 
On the wing, the influence of bankiva is dominant in the shape of 
the upper wingcoverts which is quite bankivian, while the influence of 
Sonnerat is seen in the presence of rudimentary waxy spots. The larger 
wingcoverts are greenish, not violet. 
Of the female F, hybrids, 198. 2 and 198.3, we have but incomplete 
feather-charts.
