is never pronounced. In some it is nearly absent. On the throat 

 the yellow tinge is present although faint in all the specimens and 

 is most marked medially and close to the bill. The edges of this 

 patch below and behind the black markings and therefore well on the 

 side of the head, are in all the specimens nearly pure white. In the 

 color of these markings, therefore, the birds resembled praticola, not 

 alpestris. 



Two specimens in the Bangs collection from Lance au Loup on 

 the southern Labrador coast taken on May 3 and May 14, 1899, 

 although both females, have a more pronounced yellow tint in both 

 the throat and the superciliary markings. Examination of specimens 

 in Mr. Brewster's collection shows a fainter yellow in the specimens 

 taken in April in Massachusetts than in those taken in October. 



As to measurements it will be seen from those given below that the 

 birds are large and correspond in size to the northern race, alpestris, 

 and not to praticola. 



All our specimens show considerable wear in the feathers, for all 

 were taken just before the annual August moult.
