HOUWINK’S EXPER. CONC. THE ORIGIN OF SOME DOMESTIC ANIMALS 359 
but have not succeeded in finding a plate which was not ,,colorblind”’ 
in regard to the shades of brown and black in question, each and every 
kind of plate used gave a uniformly colored picture. Mottling is also 
present on the breast of an adult cock (no. 10 of the Leyden Museum), 
collected by TEYSMAN in 1878 near Macassar (Celebes) and on the 
breast of a young cock (no. 39 of the Leyden Museum) from Java, as 
* well, as Mr. Lowe informs us, on that of a cock in the South Kensington 
Museum from Raipur. As far asI know the mottling has in none of these 
cocks the character of spangling. 
The original cock died 1918 and was subsequently badly stuffed, 
during which process the skin was evidently distended, thus ma- 
king the animal appear larger than it was during life. Still, as MR. 
HOUWINK informs me, the animal had grown considerably since he 
purchased it, which increase in size he ascribes to its grain diet and : 
forced rest in captivity in contrast to its insect -and fruit-diet and con- 
stant activity in nature, supposing of course, that the original birds 
really were bankiva’s. This opinion is supported by the large size of the 
cock (Pl. VII fig. 5) which had been hatched in Rotterdam from eggs 
imported from Indo-China. 
It results from all this, that Mr. HouwInx’s original cock certainly 
resembles bankiva more than any other species, even to such an extent, 
that — supposing it to be a wild bird — it could not be referred to any 
other species. 
In that case, a taxonomist, would however, probably, on account of 
the mottled, semi-spangled condition of its undersurface, make a spe- 
cial variety, for instance Gallus bankiva var. variegata of it, to which 
he might admit the bird from Raipur in the South-Kensington Mu- 
seum in London and the specimens with a mottled undersurface of 
the Leyden Museum althrough these are only mottled, not spangled. 
We must not forget however, that determination of partridge-colored 
Bantams would also lead us to Gallus bankiva, the cock 191.1 4 of 
Mr. Houwınk’s partridge colored Bantams even agrees in every res- 
pect with BEEBE’s descriptoin of bankiva, except that the breast is not 
uniformly brownish black, but deep black with a green gloss, and the 
hackle and saddle-feathers have a black median-stripe. In as much as 
both these characters occur however among wild bankiva’s; there is 
no doubt that, if a partridge-colored bantam-cock, such as IOI.I 3 were
