sponding plumage, when compared, are not easily confounded.

g and 9, Hakodate, October 20, 1884; numbers 236, 237. U.S. Nat. Mus. Nos. 120473-4. 
Although some additional material has accumulated since I wrote 
my previous article on the Japanese Coal Tit (Proc. U.S. Nat. Mus., 
IX, 1886, pp. 377, 378), I am unable to throw much new light on the 
subject. 
Henson’s specimens agree in every respect with those previously at 
hand from Japan. They have no crest; that is, they have not the 
feathers on top of the head any longer than European examples (for 
instance U.S. Nat. Mus., No. 111118, 3 ad., Christiania, Norway, Feb- 
ruary 27, 1887, R. Collett, coll.). The tawny tint on the under parts is 
just a shade deeper in the Japanese birds than in continental Kuropean 
specimens in corresponding plumage before me, but nearly all my 
Japanese birds are killed in autumn, while most of those from Kurope 
are spring birds. The upper surface is colored identically with speci- 
mens from France, Germany, Hungary, and Scandinavia. I stated 
before (1. ¢.) that Japanese specimens differ from Kuropean ones in the 
black on the hind neck entirely encircling the white nuchal spot and 
distinctly separating it from the gray of the back. I must confess, 
however, that this character hardly holds, for in the specimens recently 
received from Central Europe there are several in which the white is 
similarly encircled (for instance, U. 8. Nat. Mus., Nos. 111394, 111395, 
111118), while in Henson’s No, 237 the white spot immmediately joins 
the gray of the back. 
IT have also remarked that Japanese specimens are smaller than those 
from the Continent of Europe, agreeing in size closely with P. britan- 
nicus. The additional material bears out this slight difference, inas- 
much as in ten continental European examples the measures of the 
wing ranges between 59™™ (smallest 2) and 65™™ (largest 2), average 
62.5"™, those of the tail between 44™™ and 51™™, average 47™™, while 
six Japanese birds in a similar way vary between 55™™ and 59™™ (wing), 
average 58"™, and between 45"™" and 46™™ (tail), average 44.5™", Six 
PB. britannicus average respectively 58™ and 43,.3™™,
