All tliese specimens dififer from typical Swedish specimens 

 in full plumage in having the white spot on the hind neck 

 smaller and less developed. The yellowish wash of the lower 

 parts is a little stronger. The length of wing is 57-60 mm., 

 thus, on the average shorter than in Swedish specimens. The 

 most striking difference in size manifests itself, however, with 

 regard to the bill which is much more slender in the Saghalin 

 birds than in typical Swedish specimens. The development of 

 the feathers on head is somewhat different, but, as they sometimes 

 reach a length of 15 mm., I suppose the Saghalin bird must 

 be regarded to be identical with P. a. ])ehinensis, although I had 

 some doubt about this in the beginning. Nikolski has also 

 used the same name.

I have compared these specimens with P. a. halcalenals as well 

 as witli P. a. kamtschatkens'is, and have arrived at the result that 

 the tit-mouse of Saghalin represents a distinct subspecies, which 

 is lighter coloured than the former but darker than the latter.
