8944 Birds. 
so common as the foregoing ; but, from my own observation, I should 
say it was more abundant than that, at least in the south-west and in 
the breeding season. It breeds on the inland waters, which the other 
is not known to do. 
Great Skua (Stercorarius catarrhactes, Linn.) Pretty common 
along the coasts, and occasionally breeding some distance inland. 
Pomatorhine [sic] Skua (S. pomatorhinus). Not common, but has 
been observed occasionally by several travellers in Iceland. 
Arctic Skua (S. parasiticus, Linn.) Common enough throughout 
the island, for it occasionally occurs, and even breeds, on the moors 
far inland. 
Buffon’s Skua (S. Buffoni, Boie). In 1858 Mr. Wolley and I ob- 
served it several times at Kyrkjuvogr; and a very beautiful one, killed 
a day or two before at Keflavik, was brought to me on the 10th June. 
Fulmar (Procellaria glacialis, Linn.) Abundant in many parts of 
the Icelandic seas. Never enters the bays. 
Greater Shearwater (Puffinus major, Faber). [One seen. ] 
Manx Shearwater (P. Anglorum, Temm.) Remains on the I¢e- 
landic seas all the year. Commoner in the south, and especially on 
the Vestmanneyjar, than in the north. 
Stormy Petrel (Thalassidroma pelagica, Linn.) {Doubtful.] 
Little Auk (Mergulus alle, Linn.) Occurs all the year round. 
Black Guillemot (Uria grylle, Linn.) Resident in Iceland. 
Common Guillemot (U. ¢roile, Linn.) Breeds in very many spots 
on the coast, and in some places in countless numbers. 
Brunnich’s Guillemot (U. Brunnichi). [Doubts entertained as to 
its distinctness : Mr. Newton did not see it.] 
Gare-fowl (Alca tmpennis, Linn.) [Not now known to exist.] 
Razorbill (Alea torda, Linn.) Frequents the same stations as the 
guillemots, aud breeds among them. 
Puffin (Fratercula arctica, Linn.) Very common, and breeds in 
numerous localities around the coast. 
Northern Diver (Colymbus glacialis, Linn.) Not uncommon, a pair 
or so breeding on nearly every lake. 
Redthroated Diver (C. septentrionalis, Linn.) More common-than 
the last-mentioned species, especially in the south-west. 
Horned Grebe (Podiceps cornutus, Gmel.) Very generally dis- 
tributed on lakes.
