77. Larus canus (Common Gull). — A pair or two were seen 

 about the grassy slopes of cliffs near the south-west corner 

 of the island. They appeared to have young in the neigh- 

 bourhood. I found the species breeding abundantly on some 

 low fiat islands near Arasaig. 



78. Larus fusciis (Lesser Black-backed Gull). — A few were 

 noticed about the shores of Eigg. There is a large colony on 

 one of the islands near Arasaig. 



79. Larus argentatiis (Herring Gull). — Common. Breeds on 

 precipitous rocks at the southern end of the island and else- 

 where round the shores. Mr Gray informs me that when 

 cruising off Eigg in August 1877, he observed, during a gale, 

 great numbers of herring gulls. The main body sat on the 

 rocks in the north end of the island ; but, during the time 

 the yacht took in passing, hundreds came seawards in the 

 face of the storm, apparently with the greatest ease. 



80. Lariismarinus (Great Black-backed Gull). — Mr Dal- 

 gleish saw newly hatched young on an islet in a hill loch, 

 attended by their parents. A pair of black -backed gulls were 

 seen by me in the neighbourhood of the same loch, but they 

 were very shy, and I did not pay much attention to the 

 identification of them. The Eev. Mr Macpherson states 

 that as he turned the corner of a cliff " suddenly up rose a 

 large black-backed gull, who had been gorging on a dead 

 lamb." 



81. Puffinus anglorum (Manx Shearwater). — This is ^ar 

 excellence the bird of Eigg; so much so, indeed, that its Gaelic 

 name, " Fachach," is applied to the Eigg fishermen by their 

 neighbours in the surrounding islands. Old and young birds 

 alike are known by the name Fachach, but none of the 

 natives of whom I made inquiries knew it by the name of 

 shearwater. Those who had an English name for the bird 

 called it the puffin, a name by which it would appear to have 

 been long known in the Hebrides. Thus, M. Martin, in his 

 description of the Western Isles published in 1716, speaking 

 of Eum, says, " There is plenty of land and sea fowl ; some of 

 the latter, especially the puffin, build in the hills as much 

 as in the rocks on the coast," — the reference, I think, being 

 clearly to the shearwater, which, I understand, still breeds
