Difficult as it sometimes is to define with precision the characters of closely allied of birds, there are few genera where this is the case more ban in . Leaving out of view the peculiar European species. It has been a mooted question whether North America, including. Greenland, possesses one. two. or six species, owing to the strictly boreal distribution of these birds, and the fact tliiit their summer resorts are seldom in- vaded by the naturalist. The necessary means of determining the proper distri- bution of the forms and the variations witli season, locality, and sex, are scarce- ly to be met with in any public mu- seum, that of the Smithsonian Institu- tion, however, being the most complete in this respect. he most satisftxctory indications of the diflerent species and varieties his papers in the Proceedings of the Philadelphia Academy of Natural Sciences.
