498 Mr. P. L. Sclater on the 



teristic form of the Southern seas^ which he mentions as 

 occurring there in various stages of plumage. 



On referring to the report on the birds obtained during 

 the voyage of the 'Challenger^ (Chall. Rept, vol. ii., Birds, 

 p. 240), it will be seen that the Petrels met with along the 

 Antarctic ice-barrier in February 1874 were Oceanites 

 oceanica, Thalassceca ylacialoides, T. antardica, Pagudroma 

 nivea, Daption capensis, Prion desolatus, and Diumedea fu- 

 liginosa. 



In Moseley^s excellent " Notes " on the ' Challenger ' 

 Voyage are the following remarks on the Petrels of the Ant- 

 arctic ice-field : — 



"As soon as we neared the edge of the pack-ice, a Petrel, 

 which we had not seen at the islands we had left, became 

 common {Thalassceca glacialoides), and as soon as we reached 

 the ice we fell in with the beautiful snow-white Petrel 

 [Pagodroma nivea), which is never to be found far from the 

 Antarctic ice. The bird flies very much like the Whale-bird 

 {Prion) ; it settles on the water to feed ; it remains on the 

 wing late at night, when the other birds have disappeared. 

 I have seen the birds flying about the ship as late as 11 

 o'clock at night, when it was quite dusk. This bird was 

 found by Ross breeding on Cockburn Island in lat. 64° S. 



''Besides these two Petrels, we saw, when at the edge of 

 the pack, the Sooty Albatross {Diomedea fuliginosa), the 

 Giant Petrel {Ossifraga gigantea), Majaqueus (equinoctiaJis, 

 and the Cape Pigeon. Tliese birds all left us when we 

 entered the edge of the pack-ice ; they appear to remain at 

 its very margin/^ 



Adding the species of the ' Challenger' Expedition to Dr. 

 Donald's list, we find the Antarctic Procellariidse as yet 

 exactly recorded to be about eleven in number, namely : — 



Diomedea fuliginosa. Uaptiou capensis. 



Oceanites oceanicus. Prion vittatus. 



Majaqueus tequinoctialis. turtur. 



Thalassceca glacialoides. desolatus. 



antarctica. Pagodroma nivea. 



Ossifraga gigantea.
