Gould's 8upplement to the Trochilidae.*--The 'Supplement to the Trochilid•e, or Humming Birds,' now recently completed in five parts, was projected shortly before Mr. Gould's death in 188I. It forms a single folio volume of 58 plates and text, prepared and published under the direction of Mr. R. Bowdiet Sharpe, with the co6peration of Mr. Osbert Salvin. The work on the Hummingbirds, as now completed, forms six imperial folio volumes, with upwards of 400 plates, illustrating about 450 species. It is needless to say that this magnificent monograph of the most beautiful and interesting family of birds, illustrated with a delicacy and gorgeousness well befitting the gems of bird life it portrays, is not only a monument to its author, but one of the most attractive ornithological works yet produced. While the •Supplement' falls somewhat short of covering the whole field of recent discovery in respect to this group of birds, it forms a fitting conclusion to the great 'Monograph' begun by Gould in z849--nearly forty years before the completion of the ' Supplement.'--J.
