Yungipicus kizuki seebohmi (HarGiTT). (1704) 
@ ad.; Henson No. 186; Hakodate, September 10, 1884. 
In my “review” of the Japanese Woodpeckers (Proc. U.S. Nat. Mus., 
IX, 1886, pp. 120-123) I stated that I had found that the Hondo breed- 
ing birds of this species agree completely with typical Y. kizuki from 
Nagasaki, and that only my birds from Yezo were properly referable to 
Y. seebohmi. This was quite opposed to the view of the original de- 
seriber, whoreferred all his specimens from the Middle [sland to the north- 
ernform. Since the publication of my paper Mr. Seebohm has taken the 
question up again (Ibis, 1887, p. 178), remarking as follows: “In a 
series of sixteen examples in Mr. Hargitt’s collection and my own, those 
from the North Island of Japan are indistinguishable from those from 
the Middle Island, whilst those from the Southern Island are conspic- 
uously darker. On the other hand, Dr. Stejneger (Proc. U.S. Nat. 
Mus., 1886, p. 121) regards a series, apparently of nine skins, from the 
Middle and Southern Islands as practically the same, while those from 
the North Island are treated as specifically distinet. It is, of course, 
possible that Dr. Stejneger is right, and all our skins from the Middle 
Island are those of winter migrants from Yesso.” 
Sinee then I have had the opportunity of examining additional speci- 
mens from all three islands, so that the series now before me comprises 
fourteen skins, all sexes and all but one properly dated. I am there- 
fore in the position to throw more light upon the question, 
Mr. Seebolim in the article alluded to characterizes three races of Y. 
kizuki. The form from Liukiu which he calls Y. nigrescens is distin- 
guished by having “ only four very small white spots on the outer webs 
of each of the three longest primaries” (loc. cit.); in Y. kizukt proper 
these “ primaries have five small white spots on each;” while in Y. see- 
bohmi “the white spots * * * are larger and are six in number.” 
The result of an examination of my material may be tabulated as fol- 
lows:

It will be seen that there is a regular gradation from north to south, 
and that the number of spots, or their size, gives 10 absolute reliable
