402 THE ZOOLOGIST. 



at Ards, on an island in Sheephaven, and at Lough Eske. About 

 the nrst half of May to the third week there are generally several 

 pairs about the shores of Lough S willy at Carrablagh swimming 

 in deep water ; but they do not appear to breed. 



Goosander, M. merganser, Linn. — A rare winter visitor. 

 " One was shot on Killybegs Bay by H. D. M. Barton in 1879 or 

 1880, and Archdeacon Cox, of Glenties, at various times preserved 

 three specimens" (A. B.). The last were obtained on the Owenea 

 river. 



Great Northern Diver, Colymbus glacialis, Linn. — Fre- 

 quents the mouth of Lough Swilly. I have reason to be*Meve 

 some of the birds remain along the coast throughout the year. 

 The cry is unmistakable, and I heard it both in June and July from 

 my house this year, though too far out for me to make out the 

 birds. One of my men called my attention to it, saying there 

 would be a storm when the " Hollan Hawk" cried like that. 

 I have seen the Great Northern Diver here in May and in 

 September. I do not suggest that they remain for the purpose of 

 breeding. "Frequents Killybegs in winter" (A. B.). 



* Red-throated Diver, C. septentrionalis, Linn. — Not un- 

 frequent in Lough Swilly in winter, but less common near the 

 shore than the last species. I have seen these Divers here in 

 September. The eggs have recently been taken on Dunglow 

 Lake, in the north-western corner of the county. " This bird 

 has been known to breed in this locality for the past eight or ten 

 years" (A. B.). 



Great Crested Grebe, Podicipes cristatus, Linn. — I saw a 

 specimen that was shot at Bay, Lough Swilly, in April, 1879. 

 It does not appear to be common, but probably visits some of 

 the lakes. 



*Little Grebe, P. minor, Gmelin. — Breeds in many lakes 

 and takes to the sea-loughs in winter. 



Red-necked Grebe, P. griseigena, Bodd. — A specimen 

 obtained on Inver Bay, by Mr. A. R. Wallace, is now in the 

 National Museum. 



*Puffin, Fratercula arctica, Linn. — Breeds abundantly at 

 Horn Head, where it arrives from early May (or perhaps 

 earlier) to about the 12th August. Few eggs laid before the 

 end of May (1881). Puffins breed on several other parts of 

 the coast, — notably at Tormore, near Glen Head, — but in less
