 by Messrs. S. Gordon, D. Brown, H. Paget Wilkes, and 

 myself. 



30. Colymbus immer Brllnn. Great Northern Diver. 



Two seen by Nathorst off Bear Island in September 1882. 

 In Spitsbergen it is said to have been seen in September 

 1882, north o£ Bell Sound (Zool. 1884, p. 15): by KoUhoff 

 on 8 June, 1900, oft" the south-west coast, and l)y W. S. 

 Brnco on Prince Charles Foreland (Goog. Journal, 1908, 

 p. 147). Zedlitz (J. L 0. 1911, p. 300) ascribes a black- 

 throated Diver seen by him 150 yards away at sea in rough 

 weather in 1910 to C. adamsi. 



31. Colymbus stellatus Pontopp. Red-throated Diver. 



A few luiirs on the tarns in the south of Bear Island, and 

 common in the north. In Spitsbergen it is widely distri- 

 buted, breeding on most of the fresh-water pools on islands 

 and also on the mainland. The nest is built of masses of 

 Sphagnum, and is usually close to the water's edge, though 

 one on the Mofien Island was 20 yards away. In this case 

 the incubating l)ird shovelled her way to tlie nest on her 

 breast, without making any attempt to walk. Young on 

 water with parents in Sassen Valley on 17 July. 



32. Charadrius hiaticula Maticula L. Ringed Plover. 



On Bear Island, Koenig's Expedition oljtained three on 

 18 June, 1907, and on 3 July, 1908, a female with incubation 

 patch. In Spitsbergen it has been recorded on many occasions 

 since 1827 on the west and north coasts, as well as in King 

 Karl Land, but though evidently breeding, no nests have 

 hitherto been found. At Advent Bay three or four pairs were 

 found breeding about 300 ft. u\) the side of a valley on 

 21 July, 1921. In one case the bird was watched on to young 

 which had only been hatched six hours or so (S. P. Gordon) *. 



* Charadrius morinellus is said to liavc been fomul dead by Keilliau 

 in Edfre Land in September 1S27, but hi>< identification cannot be 

 depended on.
