238 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
mottled till striped with black some with a faint indication of cross- 
bars. Primaries black. Throat pale, but chocolate on the sides. Breast 
pale, almost white in the center, submarginal black stripes and some 
brown however present on all breastfeathers, especially towards the 
flanks, belly almost white except on the flanks. Tighs dirty white. 
Shanks and claws greenish-yellow. 
The hen 270.5, stuffed, (Pl. IV. fig. 6 and 7) is also a small animal, its 
comb also is reduced to a ridge in front, the small posterior part of it also 
is upright, smaller still than in 270.4 and has but 3, or perhaps four small 
teeth; very small wattles are still discernable, bill rather dark. Ear- 
coverts as of 270.4, hackles also. On the feathers of the back the white 
median stripe is conspicuous; also the light margin, in all other respects 
much like 270.4. The greatest difference with 270.4, lies in the very 
decidedly varıus-like barring of the secondaries and tertiaries, with an 
approach to pencilling on the tertiaries. The primaries are not black 
but brown gray with the outer vane more brownish. The breast is still 
whiter than in the case of 270.4, the feet and claws are lead-colored. 
The F, of the cross bankantam x Sonnerat, consequently is heterogene, 
doubtless due to the heterozygosity of the bankantam material. Of the 3 
cocks 198.1 leans much-towards Sonnerat, 270.1 is almost intermediate 
and 270.2 leans most towards bankiva. 
Of the four hens 198.2 has the comb and watiles even stronger develop- 
ed than in the case of the bankantam mother, of 198.3 nothing is known 
about this point; 270.4 and 5 both have the comb and wattles very small. All 
hens have the undersurface more or less bleached, probably due to Sonnerat- 
influence, but 198.2 and 3 have retained the cinnamon in the center of the 
breast, while this has almost disappeared in the case of 270.4 and quite 
in that of 270.5 at that place. The secondaries of 198.2 and 198.3 are not 
known, 270.5 has them mottled, 270.4 distinctly cross-barred, this latter 
difference being already present among the bankantams. 
It is worth calling attention to two points: 
a) that there is a kind of , bleaching” in the F, hens, leading to a sil- 
verpartridge-like color of the neck-feathers in one of them, 198.2, 
and to a considerable amount of white on the belly’s of all of 
them, while none of them showed the typical Sonnerat-pattern 
on its belly.
