with narrower streaks on the breast; but the difference is not great, 
except in extreme cases, and by no means constant. As to summer 
specimens (7. e., those in breeding dress), I am unable to distinguish 
differences between certain skins from Labrador, Colorado, and Alaska; 
but I have been able to examine a comparatively small number of speci- 
mens. Possibly alarge series of specimensin breeding plumage from the 
proper localities (say Labrador, Alaska, the Rocky Mountains, and the 
Sierra Nevada) might exhibit differences upon which two or more geo- 
graphical races could be based, but, with present facilities, I find the 
attempt to define differences sufficiently characteristic of region quite 
hopeless. 
It is possible that in its breeding plumage, which I have not seen, 
A. japonicus may be quite distinct from A. ludovicianus, but the four 
winter specimens examined appear to differ only, so far as constant 
characters are concerned, in the paler color of the legs and feet. 
In Proc. U. S. Nat. Mus., vol. 6, p. 95, I have with much doubt re- 
ferred to this species six examples of an Anthus obtained by Dr. L. 
Stejneger on Bering and Copper Islands, Kamtschatka, but being not 
at all satisfied that they were thus correctly determined, I proposed 
the name stejnegeri in view of their probable distinctness. I now find 
that they do not at all resemble A. japonicus, but are much more like 
A. arboreus, A. spraguei, and other species having the upper parts con- 
spicuously variegated. They seem to come near A. gustavi Swinh., 
which Mr. Seebohm says (Ibis, 1878, p. 342) occurs on Bering Island; 
but I cannot reconcile certain marked discrepancies between the only 
description which I have been able to consult (the original one by 
Swinhoe, in Proc. Zool. Soc. London, 1863, p. 90) and the characters 
presented by the series before me. I therefore incline to the opinion 
that while the species may be A. gustavi, it seems more likely to be dif- 
ferent, and probably new. 
2. Regulus japonicus. 
This kinglet is a very near relative of R. satrapa and R. cristatus, but 
is sufficiently distinct. The principal differences from the former con- 
sist (1) in the absence of the black bar across the forehead, immediately 
in front of the colored crown-patch, the whole forehead being smoky 
gray, paler toward the bill; (2) narrower black stripes on side of crown; 
(3) absence of the whitish superciliary stripe, only the orbits being 
whitish; (4) absence of the dusky streak through the eye, and (5) much 
more olivaceous sides and flanks. In all these characters it agrees with 
R. cristatus; but from the latter it differs (as does also R. satrapa) in gray- 
ish nape and side of hinder head, and in some other minor features. 
Upon the whole it is most nearly related to the European species, though 
the coloration of the nape, back, and rump is precisely that of the
