GEOSPIZA DENTIROSTRIS GOULD. 



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.
