_Geospiza dentirostris_ Gould, Proc. Zool. Soc. London 1837, p. 6;
Rothschild & Hartert, Nov. Zool. 1899 p. 163, 1902 p. 396.
This curious form differs from _G. fortis fortis_ (Charles Island!) in its
bill, which is bowed in towards the end of the upper mandible, and slightly
"toothed" on its cutting edge. The one specimen in the British Museum
certainly came from Charles Island, and we may, therefore, conclude that
the other also came from there, and there is certainly no reason to think
that it came from Chatham Island. As the skins in the British Museum
slightly differ from each other, there is some reason to suspect that they
are both aberrations of _G. fortis fortis_. Otherwise it must have become
extinct, as, in spite of special attention being paid to it, none of the
recent collectors met with _G. dentirostris_.
