148 LOTSY AND KUIPER, A PRELIM. STATEMENT OF THE RESULTS OF MR. 
dessa’s and cross breds of principally bankiva-characters may be 
the consequence of these matings. 
The nomenclature of the Indian Red Jungle Fowl has been didcdated 
lately by several writers. According to. OGILVIE GRANT we call this 
species: Gallus gallus. ROBINSON: & Kross however consider 
that the correct specific name is Gallus ferrugineus (Gmel), foun- 
ded on Sonnerat’s bird, probably from the Philippine Islands. 
They distinguish three subspecies, viz the typical G. f. ferru- 
gineus. This is the Malayan bird also occurring in Burma and 
Hainan. To the Javan race, distinguished by the dark colour of 
the hackles the authors assign the name G. f. bankiva (Temminck). 
The bird of the Indian continent receives a new name. 
Mr. Houwink bred his jungle fowls in pure race from 1912 till 
1921. During this time the stock was bred to the 5th generation. 
There. were no indications of degeneration or decreased fertility 
till then. In a few cases differences appeared, viz once in lighter 
colour of plumage, once in slight leg feathering and once in green 
legcolour. Only the first of these deviations from the typical form 
might suggest a slight impurity of the wild material. Not only phaeno- 
typically the parents and most of their offspring were quite alike 
to the representatives of this species in the Leiden-Museum, but 
also their habits and general appearance showed their wild origin. 
We hope to discuss the phenomena indicated above in a separate 
paper, but wish to point out emphatically, that the deviations deno- 
ted above, did not refer to the typical habitus nor to the size, the 
form of the comb, or any other character not mentioned above. 
In the analysis of the results of our experiments, we tried to 
observe the greatest prudence as to those characters and therefore 
we draw our conclusions with a certain restraint, but our conviction 
is that the phenomena observed in the Bankiva-strain do not in- 
fluence the results of our crossing-experiments in the slightest degree. 
The first cross Bankiva ? x Silky 4. 
We used Bankiva 201.132 (F, of the Bankiva-strain) and the 
originally bought Silky cock | 413.2 | de. 
In 1918 7 chickens were bred, viz. 
414.14, 414.24, 414.3¢ and 
414.49, 414.59, 414.69. 414.79.
