guishable with certainty from those of northern Gulls Larus argentatus, 

 for example." (Natural History of Kerguelen Island, J. H. Kidder, M. D., 

 Bull. No. 3, U. S. Nat. Mus., p. 10, 1876.) 



H. N. Moseley, in "Notes by a Naturalist on the Challenger," page 

 212 (1879) writes: "Kerguelen's Land, January, 1874. The Gull 

 (Larus Dominicanus] nests also on the open ground amongst grass tufts, 

 and the birds breed in considerable flocks together, choosing often some 

 dry place on the lower slopes of a hill-side. I saw two such places where 

 there were a few nests with young and remains of many more. No regu- 

 lar nest is made. The young are brown coloured. The old birds make 

 a great deal of noise when the young are carried off, but make no attempt 

 to protect them. The brown color of the young is closely like that of the 

 dead grass in which they lie, and under which they hide on approach of 

 danger. The colour is protective to them ; they are, certainly, very dim- 

 cult to see amongst the grass." 



"There were many in Montevideo Bay on the 2nd October and on sub- 

 sequent occasions, both adult and young. The legs of the adult in life 

 have a very yellow cast on the olive. On the ist May, about sundown, 

 I saw fourteen passing over Sta. Ana, low down, going south, and shortly 

 after at least a hundred Gulls of the same size higher up. Cold S. W. 

 winds about that time." (O. V. Alpin, on Birds Uruguay, Ibis, pp. 210- 

 211, 1894.) 



"Iris pale yellow; bill yellow, with red spot; eyelid red; tarsi and feet 

 slate-grey, in the male washed with yellow. 



"This Gull was abundant in the Straits of Magellan and Smythe's 

 Channel. The males appeared to have larger bills than the females." (M. 

 J. Nicoll, Orn. Jour. Voy. round World, Ibis, Jan. 1904, pp. 46-47.)
