1424 The Zoologist — October, 1868. 



rocks and the edges of lakes are visions of the sketclier we naturalists do not see in life. 

 I once saw a diver ashore in winter, and only once ; that was behind the West 

 Pier, Kingstown ; it was Colymbus glacialis: it had been thrown up by the waves 

 caused by a strong easterly gale, while diving among the rocks: a more helpless 

 creature 1 never met with : I got down and liberated it; it instantly dived, appeared 

 again two hundred yards off, appearing fully alive to the peril it had escaped. — Harry 

 Blake. Knox. 



Erratum.— Zoo\. S. S. 1380, line 10, leave out the semicolon between "feet" and 

 "at"; and read, "They can spring by this means ten feel at an altitude of two feet, 

 the wings being of great aid." — Id. 



Great Northern Diver breeding in Scotland. — In addition to the notes previously 

 given (Zool. S. S. 1309), I may mention that a friend also heard of the great northern 

 diver breeding in another part of Scotland. The person who described the bird to him 

 quite satisfied him as to the correctness of his siatement, and described the cry as 

 differing from any that he had ever heard the blackthroated diver to utter, and 

 agreeing, as far as my friend could trace, with ihe cry of the birds I saw in Suther- 

 land, and which I imitated in his hearing. — John A. Hurvie Brown ; Dun ipace House, 

 Falkirk, September 5, 1868. 



Blackthroated Diver off the Dublin Coast. — February II, 1867. Shot an adult. 

 March 5, 1867. Watched, through a glass, an adult in full breeding dress. January 5, 

 1S68. Watched an adull: it was in the spring moult. — H. Blake- Knox ; September 7, 

 1868. 



Little Auk in Dublin Bay. — November 7, 1867. Shot a little auk in the bay: it 

 was a young bird in its second winter, and in very rich plumage. — Id. 



Leach's Petrel in Dublin Bay.— January 10. Shot an adull of this little petrel in 

 the bay ; there were others with it. — Id. 



Eared Grebe in County Dublin and County Antrim, Ireland. — December 7, 1867. 

 To-day I was brought an eared grebe thai a fisherman's son killed with a stone or a 

 whelk-shell, while swimming off the Kolaiuore, Dalkey, County Dublin. It appeared 

 a young bird, without any of the head plumes, and was in the plumage of the " dusky 

 grebe" of some authors. A day or so later another of these grebes came under my 

 observation: it was killed at Six Mile Water, Doagh, County Antrim, and was in 

 exactly the same plumage as my bird. I believe this to be the rarest of our Irish 

 grebes. — Id. 



Kittiwake : Correction of an Error. — I find in my notes on the kittiwake (Zool. 

 S. S. 1367) that I mention that " four was the prevailing number of eggs laid " : this 

 ought to have been written " three"; in several cases 1 found more than that number, 

 but they were exceptional. In June of this year, at Barra Head, I found in no case 

 more than three, but the birds had not finished laying, and more uesls had one and 

 two eggs in than three. I see in the ' Leisure Hour' for October, in which I give an 

 account of Ailsa, I mention rock dove, rock pipit, curlew, thrush and ring ouzel: these 

 will be included in a future list. — Theodore C. IValker. 



Little Gull near Bridlington. — Mr. Jones has just sent me two little gulls (Larus 

 minutus) from Bridlington Quay, shot by Sheffield excursionists. Both have the 

 occiput and nape of the neck streaked with grayish black on a white ground, but one 

 is somewhat larger than the other. — J. H. Gurney,jun. ; September 8, 1868.
