As to the Japanese birds, the general verdict seems to be that they 
are identical with European specimens, and the material at my com- 
mand does not contradict it, so that although none of my Japanese 
specimens are in absolutely full plumage, I feel but littledoubt that the 
above conclusion is correct. The slight differences in the dimensions, 
as seen in the tables given below, seem to be fully within the limits of 
individual variation, while in the extent of the black on cheeks and 
chin, and in that of the white on the wing, I can discover no difference.

Petersen’s Nagasaki specimen differs from all the rest in having the 
inner web of the secondaries dusky except at base of the inner ones.

Urinator pacificus (Lawn.). 
A fine adult male of this interesting species opens the series of addi- 
tions to the Japanese avifauna. It was shot near Hakodate on July 
15, 1883, and is, of course, in full summer plumage, in which it can 
never be confounded with the nearly allied but quite distinct U. arcticus, 
its small size and nearly white occiput and upper hind neck being con- 
spicuous enough. 
The lateness of the occurrence of this specimen near Hakodate sug- 
gests the possibility of its breeding not far off, and the question then 
arises whether, U. pacificus may not be the breeding bird and U. areticus, 
which also occurs in Japan, the transmigrating species. A male speci- 
men of the latter was also collected by Mr. Henson at Hakodate, May 
12, 1883 (No. 120707).
