belongs, yet remains to be determined, and to which, if any, a new 
name is to be given. 
The Parus stbiricus, of Europe, is very similar in coloration and 
characters to the P. hudsonicus. The principal difference is seen in 
the cheeks, which in sibiricus are pure white, this color extending 
along the entire side of the neck, widening behind, and extending 
round towards the back. In hudsonicus the cheeks behind the eyes 
and sides of neck are ash gray, the white being confined to the region 
below or near the eye. The smoky gray of the upper part of head 
and neck in sibiricus is in a stronger contrast with the brighter 
tufescent gray of the back, and is separated from it by an obscure 
concealed whitish dorsal half collar, represented in hudsonicus only 
by a dull grayish shade in the plumage.
