300 BIRDS FROM YEZO, JAPAN—STEJNEGER. 
the scapuwiars than the Yezo and western Hondo specimens, and that 
their under surface is more deeply colored, but the Tate-Yama birds 
are intermediate to such an extent that I am now inclined to think 
that the percentage of distinguishable birds will not be found suffi- 
ciently large to warrant the separation of the typical D. japonicus and 
the “so-called D. gouldti GRAY.” Hargitt has proven conclusively 
that the true D. gouldit MALH. is not a Japanese bird, a thing I hardly 
doubted myself, but he has failed to show what the bird from Japan in 
the British Museum is, which Gray called D. gouldii! Should it ever be 
found necessary to designate this bird by a separate name, it will have 
to be rebaptized, of course. 
Picus canus jessoensis STEIN. (172) 
Heuson’s two specimens (U.S. Nat. Mus., No. 120553; Henson, No. 
214; | ¢|ad., Hakodate, November 15, 1884; and No. 120554; Henson, 
No. 215; [2] ad., ibid., November 2, 1884) agree in every particular 
with the specimen upon which I originally based the present subspecies. 
They are strongly tinged with green on the head, and hind neck; their 
entire coloration is lighter and brighter than in north and central 
European specimens before me; and the black stripes on the occiputs 
of the males are large and better defined. 
Mr. Edward Hargitt in a recent revision of the genus Gecinus (Ibis, 
18838, pp. 1-42), drawn up in the thorough and excellent manner of this 
gentleman, takes some pain to show that the present subspecies can 
not be distinguished from true P. canus because (1) his two Japanese 
female specimens are indistinguishable from specimens from the 
Vosges, France, and (2) because another Yezo female is gray, like my P. 
canus perpallidus, from the opposite coast of the Asiatic mainland. But 
it seems to me that this way of reasoning is very much the same as if 
he were going to prove that Ngithalos trivirgatus belongs to 4. cauda- 
tus proper if it should be found not to differ from 47. europwus (= roseus, 
vagans, ete.). In the first place, | would remark that the green color 
on the head is much more pronounced in the male Japanese birds, and 
that the difference between these and the European ones which I have 
seen is greater than in the females. In the second place, I regard the 
dark Norwegian birds as the types of the name P. canus; and as the 
Japanese ones to my mind are quite sufficiently different to form asub- 
species, it makes but little difference so far as their nomenclature is 
concerned whether the French birds are identical with them or not, a 
proposition which I can neither deny nor affirm, as I have seen none of 
the latter. Nor have I any reason to doubt that the differences which 
I pointed out between the Japanese and the central European (German) 
examples hold good, which I have designated as P. canus viridi-canus 
(M. & W.). Mr. Hargitt has treated but lightly the question whether 
there exist any races or subspecies of the Gray-headed Green Wood- 
pecker in Europe or not. He only says (loe. cit., p. 20): “ 1t seems to me
