observed un Waigats, ^c. 203 



34. RiSSA TRIDACTYLA. 



The Kittiwake was common on all the bird-rocks o£ 

 Novaya Zemlya. We found no breeding-places of this 

 species nor of Brlinnich's Guillemot on Waigats. 



35. Larus glaucus. 



A few scattered pairs of Glaucous Gulls breed on Waigats, 

 and we secured a whole family of father, mother, and three 

 young on an island in Dolga Bay for the British Museum. 

 We also found the species at Habarova, on Dolgoi Island, 

 and on Lntke Land, but the total number seen at all these 

 places did not equal those at Nameless Bay. Admiral 

 Markham noticed that the Glaucous Gull did not hatch all 

 three eggs ; but this may have been the result of an unfavour- 

 able season, for we met with three cases in which there 

 could be no doubt the brood consisted of three young. 



36. Larus affinis. 



Black-mantled Gulls were observed on Waigats, Dolgoi, 

 Novaya Zemlya, and at Habarova, but none were shot last 

 year. The bird shot on Kolguev in 1895 was the Siberian 

 River-Gull ; and I quite agree with Dresser's views C^ Birds 

 of Europe,' vol. viii. p. 418) respecting Heuglin's list. Until 

 more definite proof is forthcoming of the presence of 

 L. marinus and L.fuscus in these waters it will be safer to 

 exclude them from the list. 



37. Stercorarius pomatorhinus. 



We saw Pomatorhine Skuas on Waigats, Novaya Zemlya, 

 and Lutke Land, but no indication that they were breeding. 



38. Stercorarius crepidatus. 



Two Richardson's Skuas were shot on Dolgoi and one at 

 Habarova; all were of the white-breasted variety, two being 

 females and one male. The male was shot on Dolgoi while 

 endeavouring to protect its young in down, and had mated 

 with a black female; the latter kept out of range. 



39. Stercorarius parasiticus. 



Buffon's Skuas were seen on Waigats and Habarova, but 

 no nests obtained. Skuas of all three kinds were again very
