358 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
1896 from Java, to the Leyden Museum (Pl. VII fig. 1) shows the 
posterior paling of the hackles very distinctly and this paling is also 
to be seen in the case of a large cock, collected by DR. C. PLATEN in 
Daveo-Mindanao (Celebes) 28. v. 89 (Pl. VII fig. 4), the length of 
which is given as 67, the diameter as 33 cm and which is also present 
in the Leyden Museum. It is absent in the case of a cock in that same 
Museum, received from the Zoological Garden at Rotterdam on Jan. 
22. 1920 (registernumber 4677) pictured on Pl. VII fig. 5) which had 
been hatched there from eggs, brought over from Indo China. BEEBE 
describes the secondary wing coverts of the British Indian bankiva’s 
as black, glossed with purplish green. In Mr. HouwInx’s cock, they 
are glossed with green only, but in stead of being entirely black, they 
are more or less mottled with brown. The young Java-cock, already 
mentioned, has a violet gloss on its wing coverts; this is almost absent 
from the Celebes-cock, very conspicuous however on the wing coverts 
of the cock from Indo-China. 
While BEEBE describes the tailfeathers and their coverts of typical 
British Indian red junglefowl as having a green gloss only, with which 
description the tails of the young Java-cock and of the Indo-China 
one, confirm, MR. Houwink’s bird has the tailcoverts as well as the 
central tailfeathers distinctly glossed with violet, while the Celebes- 
cock presents a violet gloss on the central tailfeathers but a green one 
only on the tail-coverts. . 
The ventral surface of the neck, the breast and all the underparts of 
BEEBE’s typical British India bankiva’s are described as uniformly 
brownish black; so are those of the young Java-cock and of the cock 
from Celebes in the Leyden Museum, but this description does not fit 
the Indo-China bird, the undersurface of which is a deep black with 
a distinct green gloss. 
It is in this respect that MR. HOUWINK’S cock differs most from the _ 
descriptions of bankiva ; vts undersurface is strongly mottled with brown, 
many feathers being distinctly spangled, as in the case of a poor kind of : 
gold-spangled Hamburg. The brown is most developped on the latte- 
ral parts of a zone between the breast and the belly, hidden by the 
wings, where the feathers, although spangled, make the impression 
of two large brown spots, and on that upper part of the legs which the 
French call „la cuisse”. 
We have endeavoured to photograph this mottled-spangled condition,
