ORDER PYGOPODES. 

 ALCID^E. 



*Alca torda (Linn.) Razor Bill. 



Breeds in large numbers on rocky parts of the coast. A few 



remain throughout the winter. 

 A lea imfiennis (Linn.) Great Auk. 



Has once occurred; near Waterford, May, 1834. (Thompson.} 

 This specimen, which came into the possession of Dr. Bur- 

 kitt, is in the Trinity College Museum. 



*TTria troile (Linn.) Common Guillemot. 



Breeds on the cliffs all round Ireland. A few remain in the winter. 

 The Ringed Guillemot, now considered a mere variety, occurs 

 in small numbers associated with the type. 



*Uria grylle (Linn.) Black Guillemot. 



Breeds locally in small numbers all round the rocky coast, and 

 remains all the year. 



Mergulus alle (Linn.) Little Auk. 

 Rare and uncertain winter visitor. 



*Fratercula arctica (Linn.) Puffin. 



Summer visitor. Breeds on the rocky coasts all round Ireland. 

 A few are rarely found in winter. A white variety is in the 

 Museum. 



COLYMBID^:. 



ColymbllS glacialis (Linn.) Great Northern Diver. 



Regular winter visitor. A few birds in adult plumage occa- 

 sionally occur late in spring. 



Colymbus arcticus (Linn.) Black-throated Diver. 



Rare visitor in winter. Seen also on its northward migration late 

 in spring. 



*Colymbus septentrionalis (Linn.) Red-throated Diver. 



Regular winter visitor, and, like the former, often found late in 

 spring. The nest has been more than once found in Donegal. 

 (Field, 30th May, 1885.) Perhaps also in Sligo (Zoologist, 

 1890, p. 352.) 



PODICIPEDID^:. 



*PodicepS cristatus (Linn.) Great Crested Grebe. 



Breeds on lakes chiefly in the North and middle of Ireland, in 13 

 counties, from Galway, or, perhaps, Clare, (Lough Derg), 

 King's Co., and Queen's Co., to Down and Antrim (Lough 

 Neagh) ; but is more numerous as a winter visitor, on fresh, 

 and rarely salt water. Down, Armagh, Monaghan, Cavan, 

 and Westmeath, are mentioned by Thompson as breeding 

 quarters.
