80 CRITICAL NOTES. 
127. PUFFINUS TRISTIS. 
This is also one of Forster’s birds that has not hitherto been identi- 
fied, but it answers in all respects to P. amawrosoma, Coues. It is true 
that Forster’s bird was obtained at the Auckland Islands, and that we 
have not as yet got specimens from that locality ; but as the bird is 
exceedingly abundant at Stewart’s Island, there is little doubt but that 
it will be found on the Auckland Islands also. 
128. Procellaria Aiquinoctialis. 
This bird has been admitted into our lists on the authority of 
Mr. Ellmann, (“ Zoologist,” 1861, p. 7,473), and on a-supposed specimen 
in the Otago Museum. (List of Birds of Otago, New Zealand Exhibi- 
tion, 1865. ‘Juror’s Reports and Awards,” p. 278, No. 63.) The 
bird, however, in the Otago Museum, I found to be Prion Buanksii, and 
I think Mr. Ellman must have been mistaken in his identification. Of 
the native names given by Mr. Ellman, the first, ‘“ O1i,” is the mutton 
bird of the north, which is certainly a species of Pufinus. The second, 
“Takupu,” I do not know; but I feel sure that the Maoris would not 
give a separate name to a bird which, at any rate, is very rare on the 
coast, (for | have never yet seen it), and which is so very much like 
three others (P. Parkinson, P. Gouldi, and P. atlantica), all of which 
are common. I have, therefore, omitted it from the list. 
137. PROCELLARIA GOULDI. 
I am informed by Mr. Kirk that this bird breeds in holes on a little 
island called Kitakita, near the Kawau, and that when attacked by dogs 
fights hard for its life, often tearing open their noses with its sharp 
curved bill, and in this respect differing remarkably from P. Parkinsoni, 
which we found on the Little Barrier Island to surrender at discretion, 
without any fighting. 
139. Prion Ariel. 
A regular sequence of the Prions can be formed from P. vittatus to 
P. ariel, and, therefore, I do not think it desirable to retain more than 
three specific names, to mark each end, and the centre of the chain, 
and ariel, as the latest will have to be omitted. On the New Zealand 
coast, the intermediate form, P. Banksii, is much the most common. 
146. DYSPORUS SHERRATOR. 
T can see no sufficient difference between this bird and D. capensis, 
Licht. from the Cape of Good Hope, to warrant them being kept distinct.
