Range : — South- west coast ot" South Island. Four speci- 

 mens only are on record, killed at intervals of seventy years. 

 The first, Dusky Sound, 1849 ; second, Secretary Island, 

 1857; third, eastern shore of Lake Te Auau, 1879; fourth. 

 Lake Te Anau shores, 1899. There are credible accounts of 

 specimens having been procured and seen since that date, 

 so that there is not much basis for calling it ''extinct,^* 

 though this certainly will soon be the case. 



At the place cited, Mathews has gone fully into the 

 matter of the generic and specific names of this interesting 

 bird, and we are agreed that the name here used is the 

 correct one.
