1 66 Southern Cross. 



Two species of true Gulls occur within the Antarctic area. 

 One of these is the Southern Black-backed Gull (Lams dominicanus), 

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

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

 Lat. 64° 18' S. (c/. Saunders, 'Antarctic Manual,' p. 232). The 

 same observer olstained a specimen oi Larus scoreshii in Lat. 64° 55' S., 

 in the vicinity of the South Shetland Islands (c/. Saunders, I.e.). It 

 was probably Gahianus iMciJicus, which Mr, Hanson noticed off the 

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