320 BIRDS FROM YEZO, 
JAPAN—STEJNEGER. 
The two specimens of each group mentioned above agree in every 
point. 
The differences between the two groups, which reveal them- 
selves upon closer examination, may be tabulated as follows: 
Adult J¢. 
¢¢ in first autump. 
Bill blackish throughout. 
The drab-colored portion of the upper parts ex- 
tends only to the miadle of the back, and the 
subapical dusky band to the feathers on head, 
neck, and interscapulars is very indistinct. 
Blue of lower back, rump, upper tail-coverts, and 
under parts deeper and purer, with fewer and 
narrower terminal markings of blackish and pale 
drab-gray. 
. | 
Brown of under parts with fewer and narrower 
terminal markings. 
A distinct bluish supraloral streak, and a ring of 
similarly colored feathers round the eye. 
Wing feathers black with blue edgings of same 
tint as rump, and narrow white margins to the 
tips. 
Tail without any particular mark near tip. 
Bill eee. brown, basal half of iower mandible 
particularly pale. 
The drab color of the upper parts extends 
nearly to the rump, and the subapical dusky 
band to the feathers is very pronounced, causing 
a distinct scaly appearance. 
Blue of rump, upper tail-coverts, and under parts 
paler and dingier, with the markings more 
numerous, broader, and more distinct. 
Brown of under parts with more numerous and 
broader markings. 
A distinet whitish supraloral streak, and a ring 
of similarly colored feathers round the eye. 
Wing feathers blackish brown with pale smoke- 
gray edgings and broad white margins to the 
tips, these white tips being particularly broad 
on primary and greater coverts. 
Tail with marks as described above. 
There is no doubt that Mr. Seebohm (op. cit., p. 520) is correct in the 
main in asserting that the males during | February and] March cast off 
the terminal and subterminal bars to the feathers, which they assumed 
at the autumnal molt, leaving the bird in full breeding plumage. But 
his material must have been deficient when he states that “in the chest- 
nut feathers [of the autumnal plumage] traces only of the subtermi- 
nal dark bars are observable.” He can have had no fully molted male, 
for in such a one he would have found not only the pale terminal bar 
but also a bluish one preceding the dusky bar.
