_Psittacus madagascarensis_ Finsch, Papageien II pp. 306, 955 (1868--Finsch was not acquainted with the history of this Parrot, as he still considered Madagascar to be its home, and wondered why it had not been found there by recent collectors). _Psittacus madagascariensis_ Pelzeln, Ibis 1873, p. 32. _Mascarinus duboisi_ W. A. Forbes, Ibis 1879, pp. 304, 305 (figures), 306; Milne-Edwards & Oustalet, Centenaire Mus. d'Hist. Nat. pp. 191-205, pl. I (1893--excellent lengthy account). _Mascarinus mascarinus_ Salvadori, Cat. B. Brit. Mus. XX, p. 421 (1891--Réunion). It has been mentioned above that "Le Sieur D.B." (Dubois) described this Parrot clearly in 1674, and that it lived on Réunion, and not on Madagascar. Linnaeus in 1771 (see above) was the first to bestow a scientific name on it, though Brisson had already again described it in 1760. Linnaeus' diagnosis is, as usual, rather poor, and not quite correct[1], but his reference to Brisson leaves no doubt as to what he meant. This parrot is one of the rarest of extinct birds, only two stuffed specimens being known. One normally coloured specimen is preserved in the Museum of Natural History in Paris, and it is evidently this which has been figured by Daubenton and Levaillant, and in the "Centenaire du Muséum d'Historie Naturelle." From the latter plate my figure has been taken. The example in Vienna is unfortunately semi-albinistic, there being some white feathers on the back, wings and tail. Another normal individual, however, lived formerly in the Menagerie of the King of Bavaria, where it was depicted by Hahn in 1835. Unfortunately this specimen has not been preserved. {65} PALAEORNIS EXSUL NEWTON. (PLATE 19.) _Palaeornis exsul_ A. Newton, Ibis 1872, p. 33. Leguat was the first to mention these parrots as "Perroquets verds et bleus," and that they were wonderfully good to eat and also delightful pets.
