566 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Aves. 



always observed in timbered country, and was, indeed, so little in evidence that 

 if it does occasionally molest the sea-birds its depredations must be almost a neg- 

 ligible quantity. The absence of trees from Campbell Island may, in a measure, 

 account for the non-occurrence of the hawk. 



I am told by Captain Bollons that a whale-bird, probably this species, breeds in 

 holes on the Taumaki Islets, off the Haast River, in Westland, South Island of New 

 Zealand. 



Hob. — Southern oceans. 



Prion desolatus, Gmelin. (Dove petrel.) 



Procellaria desolata, Gmelin, Syst. Nat., ed. xiii, i, 1788, p. 562. 



A.n example obtained at Antipodes Island in February, 1907, proves to be of 

 this species, and specimens in the Canterbury Museum were taken from the same 

 locality. 



Lonnberg* asks, "Is Prion desolatus only the immature P. hanksi ? " but leaves 

 the answer open. 



Captain Bollons tells me that this Prion breeds in crevices in rocks at the 

 Bounty Islands. 



Hob. — Eastern portion of the Southern Ocean southward to the ice-barrier. 



Fam. PELECANOIDIDAE. 

 Pelecanoides, Lacepede, 1799. 

 Pelecanoides sp. (Diving-petrels.) 



As the " Hinemoa " neared the land we found the water to be dotted with little 

 diving-petrels, but as specimens were not procured I am unable to say what species 

 we fell in with. Two are known from oar waters — namely, P. urinatrix, Gmelin, 

 and P. exsul, Salvin. Mr. F. R. Chapman mentions the former one as occurring 

 at the Auckland Islands. 



Lonnbergf suggests that P. urinatrix and P. exsul represent seasonal forms 

 of the same species, or that the former is the adult and the latter the immature bird. 



By repeatedly diving and swimming under water these little birds failed to 

 increase their distance from the boat, and they took to wing. In rising from the 

 water they used their legs with a paddling action, flew a short distance with a seem- 

 ingly laboured or erratic flight, and then dropped on to the water at a supposedly 

 safe distance. 



Fam. DIOMEDEIDAE. 



Diomedea, Linnaeus, 1758. 



Diomedea exulans, Linnaeus. (Wandering albatros.) 



Diomedea exulans, Linnaeus, Syst. Nat., ed. x, 1758, p. 132. 



This bird breeds at the Auckland Islands, including the western end of Adams 

 Island, the eastern end being occupied by the royal albatros. This, as far as I
