with the broader white edges to the secondaries, we have now ascer- 
tained that it breeds in Kamtchatka; and as the smaller form has not 
at all been found in that country, it is safe to assume that this penin- 
sula is its home par excellence. On the other hand, it is certain that 
the smaller form, with the edges to the secondaries narrower and grayer, 
Chloris kawarahiba minor,* breeds in the middle island of Japan. That 
it also breeds in Yezo is probable from the fact that Henson’s speci- 
men No. 226 was taken at Hakodate on May 10, and seems also to 
be indicated by Whitely. 
The larger form is migratory in Kamtchatka. It has never been 
taken on the mainland of Asia. Consequently, it is pretty safe to con- 
clude that its only way of migration is to Japan in winter, where it is 
found numerous all through the cold season as far south as Nagasaki. 
It may breed in Yezo and in the mountains of northern Hondo, but we 
have no evidence of it, and, on the whole, I think it rather improbable. 
The results of this investigation consequently indicate that there 
are two separable forms, Ch. kawarahiba, inhabiting Kamtchatka in 
summer, migrating south to southern Japan in winter, though occa- 
sionally wintering as far north as Hakodate, and Ch. k. minor, a resi- 
dent of Japan, which is stationary at least in the southern provinces 
of that empire. Ch. sinica does not occur in Japan at all.

*T should state here that the distinction between the two forms here pointed out 
is very well shown in the beautiful plates of these birds in Fauna Japonica (Ayes, 
pls. xlviii and xlix), though not mentioned in the text.
