362 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
so called ,bekikko’s”, birds strongly resembling bankiva’s, so that 
MR. Houwin K’s cock might be such a bekikko, We therefore have the 
following possibilities to consider, as to the real nature of Mr. Hou- 
WINK’S original cock: 
a) it really is a pure bankiva 
b) it is the product of a cross of some spangled domestic breed with 
SE 
a bankiva 
c) it is the product of a Malay game crossed with a bankiva 
d) it is a case of „reversion”’ in the second generation (bekikko) of 
the cross of some domestic breed with varius. 
Let us see whether the progeny obtained by inbreeding the pair 
of Mr. HouwiNK's birds, can throw light on this matter. Super- 
ficially examined, all the cocks obtained except one, were very much 
alike and of distinct bankiva-habit, closer inspection however revealed 
minor differences between them, the most important of which may 
een 
now be enumerated. 
1. The F, cock 205.1 is much more distinctly spangled than the 
original cock, some of its hackles and wing coverts even being 
spangled. This does not apppear at first sight because the spangled 
hackles are covered by the longer unspangled ones. The under sur- 
face is quite nicely spangled. 
2. The F, cock 201.19 is almost uniformly black on its lower surface, 
the brown being practically confined to the two latteral parts of 
the , belt” between the breast and the belly, which are hidden by 
the wings. This bird therefore closely resembles bankiva. 
3. The F, cock 210.10 is still more bankiva — like, as far as it undersur- 
face is concerned, where there is hardly any brown except a minute 
brown tip on a few-breast-feathers, the latteral brown parts of the 
belt especially being absent. This cock however has decided black 
median stripes on the saddle-feathers; it also is very close to ban- 
Riva. 
4. The F, cock 209.2 is characterised and conspicuous by its almost 
evenly buff breast color, with but a few faintly spangled feathers 
and its predominantly buff belly, which however is somewhat more 
mottled with black, while its legs are yellow. 
In order to try to reconcile these facts with a not too diverse origin, 
we note that DARWIN (1. c. p. 256) mentions, that there exist spangled 
breeds of Malay game birds, that it is well known that there is a brown- 
ae
