It will be remembered that I established Sitta amwrensis clara upon 
some pale-flanked female birds from Yezo (Proc. U. S. Nat. Mus., 1x 
1886, p. 392). At the same time I remarked that “ probably the males 
will show more of the chestnut color, but judging from analogy I think 
it safe to say that the amount will be perceptibly less than in the Hondo 
birds.” This will not hold good, and the whole subspecies will have 
to be dropped, if the male sent by Mr. Henson represents the typical 
Yezo Nuthatch, for this specimen agrees in every respect with the birds 
from Hondo. Whether this is really the style of the form breeding on 
Yez is another question which can not be solved until we receive ad- 
ditional material collected at the various seasons. Having obtained 
no more typical specimens from Amur I am yet ignorant whether the 
possible differences of the Japanese birds pointed out by me (op. cit., p. 
391) have any significance or not. * 
#igithalos caudatus (LIN.). (220) 
Henson’s two specimens fully substantiate what I have said on a pre- 
vious occasion (Pr. U. S. Nat. Mus., 1x., 1886, p. 386) in regard to Jap- 
anese examples as compared with typical European birds. The meas- 
urements are practically identical, and so is the coloration. The bills 
of the Japanese specimens are the merest trifle longer than in the others. 
An adult male from Amur agrees closely with the Japan birds, but the 
vinous of the flanks is a little more vivid, hardly to be distinguished 
from a Scandinavian specimen (No. 111120). 
Seebohm’s 47. macrurus seems to me very doubtful. I have only seen 
a single Siberian specimen (Mus. C. Hart Merriam, Krasnoyarsk, De- 
cember 31, 1881). It has a tail somewhat in excess of the maximum of 
_ Al. caudatus as given in the table below, and the dusky central portion 
of the tertiaries is very restricted, but the specimen from Pomerania 
(see table) has even more white on the tertiaries than the Siberian bird. 
*T may add that since writing my review of the Japanese Paride (1. c.) I have re- 
ceived four typical specimens of Sitta albifrons from Kamtchatka, thereby verifying 
_ my determination of the Kuril specimen (p. 393) as belonging to this form.
