Two .sj)eri('s of true Gulls occur witliin the Antarctic area. 

 KM\Q. of these is the Southern Black-backed Gull {Larus dominicanus), 

 which was found by Dr. McCorniick breeding on Cockburn Island, 

 and it was also met with by Capt. Fairweather of the ' Balacna ' in 

 T.at. G4° 18' 8. (r/. Saunders, ' Antarctic Manual,' p. 232). The 

 same observer olttained a specimen of Larus scoresbii in Lat. 64° 55' S., 

 ■ in the vicinity of the South Shetland Islands (cf. Saunders, I.e.). It 

 was probably Gahiamts ^mci/?cw.5, which Mr. Hanson noticed off the 

 coast of Tasmania {cf. antea, p. 83) as very like L. marinus.
