I have carefully examined the three fine specimens of _Nestor productus_ in the British Museum, and the conclusion I have come to is that the bird described by Gould as the adult of his _N. productus_ was an abnormal specimen, and was in relation to normal _N. productus_ what the aberrations called "_superbus_" and "_esslingi_" are to _N. meridionalis_. The bills of the British Museum specimens are very different. The one from the Bell collection has the long, thin bill, but it is at least half-an-inch to three-quarters shorter than those in the Tring and Florence specimens. Habitat: Philip Island and probably Norfolk Island. One in Tring, three in London, one in Florence, two in Vienna, one in Prague, two in Leyden, one in Amsterdam, are known to me. The two specimens in the Vienna Museum were both bought in 1839. One from Ward, with a short bill, brown chest and throat, and a very wide yellow breast-band. The other from Baron von Hügel, which has a long bill and very red cheeks and chin. {47} NESTOR NORFOLCENSIS PELZELN. (PLATE 6, full figure.) _Long-billed Parrakeet_ Latham, Gen. Hist. II, p. 171 (1822). _Nestor norfolcensis_ Pelzeln, Sitzb. k. Akad. Wiss. XLI, pp. 322-325, pl.--(1860--detailed description from the manuscript of the late botanist, Ferdinand Lucas Bauer, and figure of head with an evidently abnormally developed bill. The specimen was from Norfolk Island; it had disappeared before Pelzeln's time). Latham's original description is as follows: "Length above 12 inches. Bill very long and curved, thick halfway from the base, but tapering quite to a point at the tip, and under mandible truncated at the end, colour of both, dusky; head and neck dull green; sides under the eyes, chin and throat pale crimson; upper parts of the body, wings and tail dusky; breast yellowish; belly, thighs and vent more or less crimson; tail cuneiform; legs brown." "One of these was in possession of Governor Hunter, who brought it from Norfolk Island; from the bill it seems related to the other, but the tail is cuneiform in a much greater degree, without any bars across it." The only bird of this species extant is the one in Liverpool, from the Tristram collection. Governor Hunter's specimen and Bauer's bird were both brought from Norfolk Island, but as they were cage-birds, and differed so markedly from _N. productus_, I, for reasons given under _N. productus_, believe this bird came from Lord Howe's Island. Habitat: Lord Howe's Island (?). {49} LOPHOPSITTACUS NEWTON. The huge bill and peculiar shaped crest, together with the--apparently, _i.e.,_ if the figure is correct--very short wings are characteristic of this genus. (P.Z.S. 1875, p. 350.)
