London, The British Ornithologists' Union, 1915. 8vo (21.9 x 13.8 cm). xx, 336 pp.; two folded tinted maps, eight fine chromolithographed plates by H. Grönvold. Slightly later green cloth with red morocco label with gilt title. Speckled edges.

Rare and very nicely illustrated publication in The Ibis, a famous ornithological journal (as a supplement to the 10th series). Later, an enlarged edition was published in the Transactions of the Zoological Society of London. This version, however, contains the original descriptions of new species. The fine illustrations are by the great Danish bird painter Henrik Grönvold (1858-1940) . The ibis is the oldest and most beautifully illustrated bird journal ever published. Provenance: on the front free endpaper recto the bookplate of the Dutch naturalist and former director of the Amsterdam Zoological Museum, Lieven Ferdinand de Beaufort (1879-1968). Plate I bound in as frontispiece. Some light, marginal spotting, but generally clean. A very good copy. Nissen IVB, 689; Zimmer, p. 474.
