Of these animals we know 280.1; 3; 4; and 7, none of which show 
Sonnerat influence, and all of which resemble the original bankantams 
except 280.1 and 280.3 which have practically pure black breasts.

THE CROSSES WITH GALLUS VARIUS 
In 1915 a beautiful varıus-cock was received from MR. DE Bas of 
the Hague; unfortunately this animal also succombed already in the 
year following upon the one in which it reached Mr. HOUWINK. 
Fortunately this cock had already, in the peculiar way described in 
Genetica V p. 43, paired with the bankantam hen 201.2. Notwith- 
standing the fact, that Mr. HOUWINK saw the copulation take place, 
every evening, during a week, but 3 of the 10 eggs laid, hatched a chick, 
these got the series-number 196.

between the hen and the cock did not begin until towards August. It is to be 
regretted that the date of the birth of these important chicks is not recorded.
