On certain Birds of New Zealand . 
PlJFFINUS GAVIUS. 
Dr. Duller gives P. opisthomelas (Coues) as a synonym of 
this species. In this he probably follows me, as he does not 
say that he has been able to compare it with any typical spe¬ 
cimens. But this is another of my mistakes that he has un¬ 
fortunately adopted without acknowledgment; for on a fur¬ 
ther examination I find that our bird always has the under 
tail-coverts pure white, while in P. opisthomelas most of them 
are fuliginous. P. gavius can hardly be said to “ enjoy a wide 
oceanic range,” when it has never yet been found out of sight 
of New Zealand. 
Thalassidroma fregata. 
This species is far more plentiful in New Zealand than T. 
melanog aster. 
Procellaria parkinsoni 
is common all round the New-Zealand coasts, and not by any 
means confined to the Hauraki Gulf as Dr. Duller would 
seem to imply. It breeds in the Bimutaka mountains near 
W ellington. 
Daption capensis. 
I cannot agree with Dr. Duller that the history of this bird 
has been fully recorded when even its breeding-place is not 
yet known. 
PHALACROCORAX NOVJ3-HOLLANDLE. 
This bird differs from European specimens in never getting 
so white on the head and neck; but this is not, in my opinion, 
sufficient to entitle it to rank as a distinct species. Dr. Dul¬ 
ler, in his quotation from my catalogue, omits the first part 
of the sentence, in which I say that the change in my opinion 
about this bird was owing to my having visited the South 
Island. 
Phalacrocorax brevirostris. 
According to Mr. H. Travers this bird is not found in the 
Chatham Islands. 
Phalacrocorax punctatus.
