Nests in pine-trees; nest and eggs not peculiar. *»* Thus passing in review the 23 " solid " species of Dendroeca, with two varieties lately introduced, I may allude to two species described by early authors, but never identified. 1. Sylvia montana, Wilson. This I have given (in the orig. ed., p. 105) some reasons for sup- posing to be a young D. virens. 2. Sylvia carbonata, Audubon.
