250 THE ZOOLOGIST. 



Arctic Tern, S. macrura. Occurs with the last named. 



Little Tern, S. minuta. Breeds in small colonies of from 

 two to twenty pairs at intervals along the Merionethshire coast. 

 On June 13th, 1894, I found six nests in the course of a few 

 minutes. One of the birds flew towards me, hovered, and alighted 

 upon its nest within fifty yards. The eggs are hatched about 

 July 3rd. 



Sabine's Gull, Xema sabinii. An example occurred after 

 three days of very rough weather, Oct. l?th, 1891. It is now 

 in the collection of Sir Vauncey Crewe at Calke Abbey. 



Ivory Gull, Pagophila eburnea. Two occurrences at Aberyst- 

 wyth within the last thirty years, both the birds having passed 

 through the hands of Mr. Hutchings. 



Kittiwake, Rissa tridactyla. Invariably appears inshore 

 after rough weather. During exceptional storms many are beaten 

 down into the sea and drowned. Has no breeding station on the 

 Cardiganshire coast. 



Black- headed Gull, Larus ridibundus. A common winter 

 gull, and almost equally numerous in summer, when many 

 remain on the Dovey, and are seen passing to and fro between 

 the river and the hills. I also found plenty at Barmouth at the 

 end of June, and on July 3rd saw two speckled young birds in 

 the river, so that there is probably a nesting-place somewhere 

 in the hills. A few pairs seem to have attempted to nest at 

 Mochras Island, as they noisily mobbed some visitors. Amongst 

 rushes I found what I supposed to be their nests, and picked up 

 an undoubted egg. 



Little Gull, L. minutus. Capt. G. W. Cosens saw an 

 example in mature plumage at Glandovey, and noticed the black 

 under side of the primaries. Two have occurred to Mr. Hutchings, 

 one of them during the storm of October, 1891, which brought 

 the Sabine's Gull and Grey Phalaropes. 



Iceland Gull, L. leucopterus. Not at all infrequent, but, 

 curiously enough, appears not to have occurred in Pembrokeshire. 

 After a very severe gale some years since Iceland Gulls were 

 plentiful off Aberystwyth. One, in immature plumage, obtained 

 at Borth about Nov. 1st, 1894. 



Glaucous Gull, L. glaucus. Mr. Hutchings has preserved 

 three or four, one of them a remarkably fine old bird. Once seen 

 by Mr. F. T, Fielden at Borth.
