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 (?).

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.)
