'Type now in collection of the British Museum. 



^This specimen is referred with some doubt to O. bremrostris,\i\xt if it is not the 

 same form it is certainly distinct from the ordinary " Cactornis" of the same island 

 ( G. fatiijiitd). It is apparently an adult female, with wholly light cinnamon colored 

 bill and streaked plumage, lacking the buffy margins of the middle and greater wing-
