_Hemignathus lucidus_ Lichtenstein, Abh. d. Kön. Akad. Wissensch.
Berlin 1838 p. 451, pl. V figs. 2 [male] 3 [female] (1839--Oahu).
_Heterorhynchus olivaceus_ Lafresnaye, Mag. de Zool. 1839 pl. X. and
text (Oct. 1839).
The Oahu form of _Heterorhynchus_ is now extinct, and specimens are only,
as far as we know, preserved in the Museums of Berlin (types of _H.
lucidus_), Boston (type of _H. olivaceus_), Francfort, Paris, Leyden,
London, Cambridge, Liverpool.
In 1838 Deppe saw this bird in great numbers flying round the flowers of
the banana plantations. As the bird was apparently common, it is quite
possible that specimens are preserved in several other collections, and it
would be most welcome if the officials of continental Museums would give
information in case they should find specimens of this interesting extinct
bird.
Habitat: Oahu.
