The length of culmeii in the adult birds is 11-12 mm. 



The average length of wing in Swedish adult specimens is 

 67-72 mm., and the length of culmen about 10 mm. 



Hahtert^^ quotes the measurement of the wing of male^ to 

 be 73-76 mm., that of females to be 69-72 mm. and the length 

 of bill to be 9-10 mm. 



Should this Tree-sparrow deserve a third name, it might 

 belong to Stejneger's saturatus. 



NiKOLSKi collected only two young specimens of this species 

 in the southern part of Saghalin (Taczanowski).

The present series proves that the males of this species 

 require more than a year before they quite attain full plumage. 

 In this the back is deep maroon with hardly any black streaks 

 and the white wing-patch is much larger, the yellow of the lower 

 parts more intense and the band on the foreneck more broadly 

 developed than in younger, though adult, males. The latter show 

 several developmental stages of the plumage growing less and 

 less intense in its colours (less red above and less yellow below)
