CATALOGUE OF CANADIAN BIRDS. 49 



I noticed one of these birds flying overhead among a number 

 of common terns on the nth June, 1893. I was visiting some 

 rocks on the St. Lawrence below Rockport, Ont., at the time, and 

 from the way in which it hovered along with the terns thought it 

 possible it might be breeding there, though I failed to find any 

 sign of a nest. This is the only time I have observed the bird so 

 late in the season. {Rev. C.J. Young.) 



60.1. Little Gull. 



Lams ?ni?mtus Pall. 1771. 

 A specimen obtained on Sir John Franklin's first expedition, 

 was determined by Mr. Sabine to be a young bird of the first year 

 of this species, exactly according with Mr. Temminck's descrip- 

 tion. {Richardson?) 



XXIII. RHODOSTETHIA Macgillivray. 1842. 



61. Ross Gull. Cuneate-talled Gull. 



Rhodostethia rosea (Macgil.) Bonap. 1850. 



This is both a rare and a far northern species. Four specimens 

 have been received by the museum at Copenhagen, from Green- 

 land, three of which were shot in Disco bay, and the fourth near 

 the Sukkertop. {Arct. Man.) Two specimens of this gull were 

 killed on the coast of Melville peninsula, on Sir Edward Parry's 

 second voyage. Commander Forester also found this species in 

 Waygate strait, which is probably one of its breeding places. 

 {Richardson.) Found .breeding at Ekomiut, in the district of 

 Christianshaab, Greenland, August 15th, 1885. {The Aiik, April, 

 1885.) A young bird of this species was taken near St. Michael, 

 Norton sound, on October 15th, 1879. {Nelson^) Abundant at 

 Point Barrow, autumn visitors only. They appeared in large, loose 

 flocks, coming in from the sea from the southwest and evidently 

 going northeast. None seen to return in the spring. They likely 

 breed north of Wrangell island. {Murdoch.) 



XXIV. XEMA Leach. 1819. 



62. Sabine Gull. Pork-tailed Gull. 



Xema sabijiii (Sab.) Leach. 1819. 

 Said not to breed further south in Greenland than lat. 75° 30' 

 N.; also common at Sabine island, Melville bay, lat. 75° 30' N.
