THE BIRDS OF AUSTRALIA. 
and a photograph taken by Hall and reproduced in Campbell’s Nests and Eggs, 
opp. p. 912, is obviously a true palpehrata. 
This species also breeds on the Auckland Islands, Antipodes Island, and 
Campbell Island, while another form breeds on South Georgia. For this may 
be used Solander’s name, as here again a most beautiful description, which I 
reproduce, was prepared by him from a bird killed south of Terra del Fuego. 
I find that the two species can be separated by the shape of the biU and 
the character of the groove in the lower mandible, as well as the colour of 
the skin in the groove which has been commonly used. Eagle Clarke’s conclu- 
sions that the Grey-backed bird is a more southern one, I would accept ; and 
that the sooty one breeds in a warmer region, would Seem as certain. That 
both occur together at sea is only what would be expected, as it seems 
a common law that the Antarctic breeding birds range north in their 
non-breeding season. 
The type-locality of P. palpehrata being 64° S. 38° E. — the nearest breeding- 
station from which birds are available being Kerguelen Island, about 50° S. 
70° E. — for the time being these are accepted as typical. The extract quoted 
shows Hutton’s var. cornicoides to be based upon typical palpehrata, and I 
would designate as type-locality of Hutton’s variety the breeding-resort of 
P. palpehrata. The limits of range given by Hutton prohibit the acceptance 
of cornicoides for the New Zealand breeding bird, which I have therefore 
named P. p. Jiuttoni. These specimens from New Zealand seas are noticeably 
paler on the mantle than the Kerguelen Island birds, while the South Georgia 
breeding-form should carry Solander’s name of antarctica, as that splendid 
ornithologist carefuUy detailed one of these birds, as here given:—-
