MONOGRAPH OF THE PETRELS. 



Professor Giglioli during the voyage of the " Magenta," records the species as 

 having been met with on February 16th, 1866, in Lat. 42° 53' S., Long. 26° 11' W., 

 and on March 4th in Lat. 42° 51' S., Long. 10° 15' E. ; one example was again seen, 

 accompanied by several P. turtur (= P. desolatus), on March 20th, in Lat. 41° S., 

 Long. 66° 04' E. On July 6th, while in the Pacific Ocean, in Lat. 37° 46' S., Long. 

 174° 48' W., more birds reappeared, and remained till July 27th, in Lat. 38° 06' S.,' 

 Long. 111° 50' W. ; again it was observed in September on the journey from Callao 

 to Valparaiso, and followed the ship till within sight of Aconcagua, Chile. 



This species is abundant in the Cape Seas, where the type was 

 obtained by Sir Andrew Smith, and other records of its occurrence are Table Bay 

 (Layard), Pondo Land, where the birds were often driven inland in rough weather 

 (Shortridge), Natal, where hundreds of dead and dying birds were washed ashore during 

 a great gale in August, 1862 (Gurney, Ibis, 1864, p. 355), and in similar conditions, 

 others were found at the mouth of the Zambesi River (Ibis, 1864, p. 338) by Sir John 

 Kirk, who further reports these birds in the Mozambique Channel, and as abundant 

 off the Seychelles, whilst Dr. Dickinson found them off the Comoro Islands. 



Further records are from Lat. 41° S., Long. 46° E. ; Lat. 43° S., Long. 107° E. ; 

 Lat. 44° S., Long. 138° E. (Layard, Ibis, 1867, p. 460). Captain Armson obtained 

 specimens in the Crozets, and a bird collected there by Mr. Ring is undoubtedly 

 P. banksi. Professor Vanhoffen records the species in Lat. 56° S., Long. 30° E., and 

 Dr. Husker from Kerguelen, but hitherto the only Prion I have seen from that island 

 is P. desolatus. Specimens of P. banksi were procured, in Lat. 42° 23' S., Long. 20° 32' 

 E. (N. Hanson ; Sharpe, Rep. Voy. " Southern Cross,''' p. 159) ; Lat. 35° 20' S. s Long. 

 9° 43' W. (Earl of Crawford) ; Lat. 35° S. ; Long. 0J° E. (Macgillivray) ; Lat. 

 (Sir George Grey) 35° 1' S., Long. 6° 15' E. 



The species has been traced across the South Indian Ocean to Australia, and is 

 apparently generally distributed on both sides of that Continent, whence it ranges to 

 the New Hebrides and Celebes ; a skeleton from the latter locality has been recorded 

 by Salvin in the " Catalogue of Birds of the British Museum," XXV., p. 434 ; but it 

 was not mentioned by Dr. Meyer and Mr. Wiglesworth in their " Birds of Celebes." 



The British Museum contains specimens from New Zealand, where Hutton 

 considered P. banksi to be the commonest species, but Sir W. Buller did not agree, and 

 thought P. turtur (P. desolatus) more plentiful, as it occurred on every part of the coast, 

 where P. banksi was rare. 



Dr. Wilson, of the " Discovery," found P. banksi on Macquarie Island, and in the 

 Auckland Islands, where it was breeding ; this is at present the only authentic account 

 of its nesting (Nat. Antarct. Exp. Birds, p. 106). 



Banks' Blue Petrel is also recorded from the Antarctic regions, and Dr. H. O. Forbes 

 mentions a specimen in the Liverpool Museum procured by Sir J. Hooker during the 

 voyage of the " Erebus " and " Terror" off Victoria Land in Lat. 74° S. (Bull. Liverp.
