took their eggs, the first I met with, on the 21st of June, fresh 
laid. This tern is very abundant, and I noticed them at mid-day 
resting on the shingle, with their breasts pressed to the ground, in 
flocks of several hundreds: late in the evening we came across them 
roosting on the fells in large flocks, at a height of three or four 
hundred feet above the sea. We often were delighted by watching 
them hovering over the meadows in flocks, feeding on insects. 
119. Rhedostethia Rossi, Sabine. Cuneate-tailed Gull.—A 
specimen of this exceedingly rare arctic gull was shot on the island 
of Suderoe, when in company with a blackheaded gull (C. ridi- 
bundus), on the 1st of February, 1863: it was sent by Herr Miiller 
to the University Museum of Copenhagen. This specimen is 
referred to by Professor Newton in the ‘Ibis,’ 1865, p. 103, as 
being one of the five specimens known to him to be in scientific 
collections in Europe. Herr Miiller informed me that there was a 
second specimen of this bird in the Museum at Copenhagen. 
~ 120. Xema Sabini, Leach. Sabine’s Gull.—Herr Miiller records 
the capture of this bird in Feroe, and gives the measurements of 
one shot near Thorshavn on the 26th of January, 1856 (Feroernes 
Fuglefauna, p. 72). 
121. Chroicocephalus ridibundus, Linn. Blackheaded Gull. 
Native name, Fransatedna.—There is only one locality in the 
Feroe Islands where this bird breeds at present, and that is a little 
island in Toftvatn, a lake in Osteroe. I visited this lake on the 4th 
_ of June, and noticed some seven pairs flying over the water; the 
islet on which they breed is not above fifty yards from the shore, 
but the water between is deep and was very cold on the occasion 
of my visit: I swam, however, to the islet, and found several nests, 
one with a single egg, another with three deeply incubated ; a half- 
grown young one ran away from between my feet when I landed on 
the islet, and took boldly to the water. It is only of late years that 
this bird has been noticed breeding in Feroe, having probably 
been overlooked, for Wolley mentions that in a swampy valley, 
where he found the rednecked phalarope breeding in 1849, he was 
told that a pair or two of blackheaded gulls had been seen the 
summer before. 
122. Rissa tridactyla, Linn. Kittiwake. Native name, Rida.— 
Miller mentions that this bird is seen in winter, though of course 
not in the same abundance as in the breeding-season, when it is by 
far the most numerous of the sea-gulls in Feroe. No words of
