his mistake" in describing Graucalus melanops as Collu- 

 ricincla concinna, he did not also state to whom that disco- 

 very was due. 



Thalassidroma fregata. 



My experience differs from Captain Hutton's ; for I have 

 always found Thalassidroma melanogaster more plentiful on 

 our shores than T. fregata. 



Procellaria parkinsoni. 



When I left the colony all the known examples had been 

 obtained in the Hauraki Gulf. I am aware that the species 

 has since been met with in Cook's Strait and on other parts 

 of our coast. 



Daption capensis. 



What I meant^ of com'se, in the words quoted by Captain 

 Hutton, was the known history of this familiar species ; for I 

 had nothing to add to it. It is equally common on the At- 

 lantic and Pacific Oceans, and many excellent accounts have 

 been written of it. 



PhALACROCORAX NOV^-HOLLANDIiE. 



I cannot see how Captain Hutton^s visit to the South Island 

 in any way affects the argument. The only question is 

 whether the diffference of plumage (admitting it to be con- 

 stant) entitles our bird to rank as a distinct species. I follow 

 Mr. Gould in believing that it does. 



Phalacrocorax brevirostris. 



This species certainly does occur in the Chatham Islands; for 

 I shot a specimen there myself during a short visit in 1855. 



Phalacrocorax punctatus. 



I stated (B. of N. Z. p. 336) in reference to this figure 

 that I was by no means certain whether this was not only 

 a seasonal state of plumage. I cannot^ however, accept 

 Captain Hutton^s dictum on this point till he gives some facts 

 in support of it. Mr. Fuller, who has collected scores of these 

 birds at all seasons, rejected this view, and assured me that 

 he had found the crested and the uncrested birds breeding in 

 separate pairs at one and the same time. Both Dr. Haast
