PUFFINUS ASSIMILIS, Gould. 
Allied Petrel. 
Pujjinus assimilis, Gould in Proc. of Zool. Soc., Part V. p. 156. — lb. in Ann. and Mag. of Nat. Hist., vol. xiii. p. 366. 
Australis, Eyton. 
All the specimens of this species that I have seen were procured on Norfolk Island, where it is said to 
breed ; consequently the seas washing the eastern shores of Australia may be considered its native habitat ; 
it is evidently the representative of the Puffinus obscurus of Europe, which it so much resembles, and to 
which it is so nearly allied, that assimilis appeared to me to be the most appropriate specific appellation 
I could apply to it. On my homeward voyage I saw numerous examples flying off the north-eastern end 
of New Zealand, and this I regret to say is all the information I have to communicate respecting it. 
Crown of the head, all the upper surface, wings and tail sooty black ; sides of the face, throat and all the 
under surface white ; bill dark horn-colour ; tarsi and toes greenish yellow ; webs yellowish orange. 
The figure is of the natural size.
