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. 
JDaption capensis. 
What I meant, of course, 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^-hollandi^e. 
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
