In April 1860, I brought under the notice of the Society a classified list of the Birds of Linlithgowshire. The list was accompanied with notes, “On the Structure and Habits of some of the Rarer Species.” After the publication of the Society's Proceedings, several communications were addressed to me by well-known ornithologists, chiefly with the view of ascertaining, if some of the rarer species named had been known to nest in the district. This led to the revision of the list, and to the exclusion of such species as are either rare visitors only, or winter birds of passage. A List of the Birds of Berwickshire, drawn up on the same plan, is now associated with this.
