Notwithstanding its geographical position, the present form is appar- 
ently more closely allied to piudk-ola than to any of the others. In 
size it is practically the same and in color it differs only in the darker 
upper surface — particularly the back, which is more blackish — and in 
the usually yellow eye})row. Birds occur, however, principally in 
areas of inosculation with leucolmma., which with difficult}" could be 
distinguished from some examples of praticola. Compared with arcth 
cola, whose range probably meets that of nierriUi somewhere in British 
Columbia, the latter is much smaller, darker above, with the throat at 
least, the eyebrow frequently, tinged with j^ellow. From both alpestris 
and hoytl its lesser size and blackish back furnish easy means of sepa- 
ration. 
The young of merrilll are not with certaint}' distinguishable fi'om 
specimens of praticola of the same age. The specimen described by
