Latham's original description is as follows: "Length thirteen inches. Bill very long and hooked, and upper mandible measuring almost two inches, the under three-quarters, colour dusky; plumage in general greenish ash, inclining to brown, and clouded here and there with orange as in the 'Crossbill,' but the edges of the feathers of the back dun colour; all the under parts of the body mixed yellow and dull orange; rump dull red; under wing coverts dull yellow; thighs brown; the quills reach almost to the end of the tail, which is somewhat, but not greatly, cuneiform; both quills and tail are brown, the former marked on the inner webs with five or six whitish bars; legs dusky, toes very long. Inhabits New South Wales. I met with a fine specimen of it in the collection of Thomas Wilson, Esqre."
It has long been a question whether Nestor productus of Gould and Nestor norfolcensis of Pelzeln were really distinct or only individual varieties of one species. I had for a long time considered them to be merely individual varieties, for I could not persuade myself that a small island like Philip Island, almost contiguous to Norfolk Island, could have a different species of Nestor to that found on the larger island. Since commencing to write this book, however, I have come to somewhat different conclusions. In the first place no special locality is given for N. productus by the earlier authors, in the same way as in the case of Notornis alba, which, like the Nestor, was said to come from N. S. Wales. This fact is easily explained, as N. S. Wales and Norfolk Island were both penal settlements in the early days, and there was intercourse by regular vessels plying between these colonies and Lord Howe's Island. Now we find in the case of several other birds that distinct local forms occur on Norfolk and Lord Howe's Islands, while as far as I know there is no other record of a distinct bird from Philip Island. I therefore believe that Nestor productus inhabited both Norfolk and Philip Islands, and that all specimens extant are from Philip Island, where it lingered some years longer than on the main island, while the specimens of Ferdinand Bauer and Governor Hunter, and possibly the supposed N. norfolcensis of
