THE BIRDS OP AUSTRALIA. 
A large Puffinus, from the island of Euopoa and (p. 194) : “ The name is 
unidentifiable, unless we regard it as expressive of a valid species.” 
I can trace no writer who has made a serious attempt to dispose of this 
obstacle. To me the position of the island of Euopoa seemed to be the key 
of the situation, as obviously the bird was a Pufflnus, and knowledge of the birds 
from the island of Euopoa would solve the problem. I have been unable to find 
any such island as Euopoa among the Pacific Isles in any recent atlas. A 
natural conclusion was that, inasmuch as the bird described was in the British 
Museum from the Pacific as early as 1785, it might have been brought back by 
Captain Cook. Consequently search through the records of his voyages should 
discover the position of this mysterious isle, but it did not. The Solander MS. 
seems to solve our puzzle, as the word “ Euopoa ” is there given as being 
the “ na7ne used hy the Pacific Islanders for a hlach Pufflnus reseynbling 
P. griseusP At least that is how I read the note given with the description of 
the latter bird, where I will point it out. 
My conclusion is, then, that the island of Euopoa is non-existent, and that 
Latham’s mistake has arisen through his misreading a label or misunderstanding 
a spoken communication regarding the Pacific Pufflnus. 
Having disposed of the erroneous locality, the identification of the Pacific 
Petrel seems simple. The description of the bill is undoubtedly that of a Pufflnus ; 
the length in proportion to the breadth shows it to have been a long-tailed bird j 
the colour of the feet is quite that of the P. chlororhynchus group, and the 
lead-coloured, much-hooked bill is met with in the form I named Pufflnus 
chlororhynchus iredali, which breeds at the Kermadecs. My description reads 
{Bull. Brit. Orn. Club, Vol. XXVII., p. 40, 1910) 
Differs from typical P. chlororJiyTichus in its generally larger size and darker colour, and 
in having a stronger lead-coloured bill. The bill of P. chhrorhynchus is flesh-colour with dark 
tips. 
The wing-measurements of the Kermadec bird are 315-317 mm., and of the Australian 
form 277-285 mm. 
Hab. Sunday Island, Kermadecs. 
I can see no valid reason whatever for the non-recognition of P. pad flea 
Gmelin, and propose to designate as the type-locality of that species, “ Pacific 
Ocean, breeding at the Kermadec Islands,” and sink my P. chlororhynchus 
iredali as on absolute synonym of Pufflnus pad ficus pad ficus Gmelin, and 
Pufflnus padflcus must be used as the species-name of the forms hitherto 
called P. chlororhynchus Lesson. 
Recently it has been suggested to prefer Gould’s name of P. sphenurus 
to Lesson’s P. chlororhynchus, and certainly the description given by Lesson is 
brief enough {Traite d’Ornith., p. 613, 1831): Pufflnus chlororhynchus. Bee
