The present contribution to the fish-fauna of Lord Howe Island is the result of an examination of two collections obtained in 1900. The first, made by Mr. W. S. Thompson, a resident on the island, to whom the Trustees owe other courtesies, consists of but half-a-dozen species. One of these, however, is an interesting new Labroid. The second collection is the result of gatherings by our friend Mr. Frank Farnell, Honorary Visiting Magistrate to the island. It is more extensive, and, though not yielding novelties, enables me to add six species to the known fauna, and to specifically recognise an undetermined record, namely. Scarus pyrrhostethus, Richardson. I have also added two species obtained in 1894, but not previously recorded.
