Ten species of North American birds arc named by Mr. B. M. Hasbrouck as missing. Of these, two the great auk and the Labrador duck are believed to have become extinct, while the following eight, through scarcity or diminutiveness, were "lost" with the taking of the first specimens, and are now being eagerly sought: The carbonated warbler, blue mountain warbler, small headed warbler, Cuvler's kinglet, Townsend's bunting, Brewster's linnet, Bachman's warbler and the Cincinnati warbler.
