That the white-breasted form of Ponapo would have young like those of H. p el e wen sis, from 

 which it only differs in size and relative lengtli of bill and tail, can hardly be doubted by those who have seen 

 the two species ; consequently, it seems best that the two forms be treated as distinct for the present ; though 

 more material may perhaps ultimately show that the view of Dr. Finsch is correct, and that the white-breasted 

 specimens are the females of the cinnamon ones. If such be the case, the sexes evidently differ in colouration 

 from the very first.
