a A. H. Clark. 



b Mr. Austin H. Clark (Proc. Bost. Soc. N. H., Vol. 32, 1905, 268, 269) considers this 

 an immature plumage; but I strongly suspect that in reality it represents a dichro- 

 matic phase, my reasons for this being that none of five specimens examined shows the 

 slightest evidence of immaturity in texture of the plumage or any other character. 



c Six specimens. 



d Three specimens.
