This graceful Fulmar, which, in its silvery-grey plumage, so much resembles the 

 Fulmar of the northern hemisphere, is widely distributed over the southern oceans, and 

 the following extract from Professor Reichenow's recently published memoir on the 

 birds obtained by the German Antarctic Expedition, under the leadership of Dr. E. 

 von Drygalski, records the geographical distribution of the species (Deutsche Siidpolar 

 Exped., IX., Zool., L, p. 553) : — " South Georgia, nesting ; South Shetland Islands, 

 Feb. ; Joinville Island, Dec. ; Paulet Island, Aug. ; Louis Philippe Land, Dec, breeding 

 (Andersson, Wiss. Ergebn. Schwed. Siidpolar Exped., V, Lief. 2, p. 43, 1905) ; South 

 Orkney Islands, Nov., March; Weddell Sea, 71° 22' S., March (Scottish Antarctic 

 Exped.) ; Bouvet Island, Nov. ; Kerguelen Island, May (McCormick) ; Edge of the 

 Pack Ice, below 64° 14' S. Lat., and 55° E. Long., in Kaiser Wilhelm II. Land (Van- 

 hoffen) ; Ross Sea (Wilson) ; Pack Ice below 63° 3' S. Lat., and 161° 42' E. Long., 

 Dec, Feb. (Hanson) ; 66° S. Lat., Feb. (Voyage of the " Challenger ") ; 70° 40' S. 

 Lat., 102° W. Long., March (Belgian Antarctic Exped.) ; Palmerston Archipelago, 

 Feb. (French Antarctic Exped.). 



It will be seen from the above list of localities that the species is found in 

 the neighbourhood of the Antarctic Pack Ice from August to March, and I am of Dr. 

 Wilson's opinion that it is a migratory bird, as it has been observed in the southern 

 seas during the summer months, December, January, and February, while its 

 furthest northern records occur during the southern winter, when it retires to the 

 open sea. Dr. Wilson observed it in June and July, and saw a few examples the day 

 before entering the Pack Ice in Lat. 59° 18' S., Long. 138° 2' E., while it gradually 

 increased in numbers as a northerly course was taken to the Macquarie Islands, 

 as far as Lat. 57° 25' S., Long. 151° 45' E., but from January, 1902, to February, 1904, 

 none were seen. The birds were not observed near the coast of Victoria Land during the 

 winter spent by the " Discovery " in McMurdo Sound, but they again became 

 abundant towards the Balleny Islands, about Lat. 67° S., again disappearing on crossing 

 the Antarctic Circle. Dr. Wilson considered the above-named islands a likely breeding- 

 place, as large numbers were seen there, and he believes that they may be found nesting 

 on Scott Island, in Ross' Sea. It will therefore be noticed that P. glacialoides does not 

 habitually frequent the ice, but keeps almost entirely to the open ocean. Dr. Wilson 

 says that on the voyage from New Zealand to Cape Horn, in a higher latitude than 

 is usually taken, the species was met with on June 19th, and two days later Thalassceca 

 antarctica followed the ship, and remained with it till within a few days of Cape Horn, 

 while P. glacialoides accompanied the expedition in considerable numbers through the 

 Straits of Magellan to Port Stanley, in the Falkland Islands, which was reached on 

 July 22nd. During the whole of this time no ice was sighted.
