1 92 2. J Birdit of Sp'itsherqen and Bear Island. 177 



cases Jill three may be found on the same ledge, crowded 

 together, and rendering the authentication of the eggs some- 

 what difficult, but there is a distinct tendency for the ringed 

 birds to associat * in little groups among the far more numerous 

 Briinnich's Guillemot. Nearer ('ape Bull, Paget Wilkes met 

 with a colony of Common Guillemots breeding on the flat 

 top of a stack in great numbers, while Briinnich's Guillemots 

 were breeding on the flanks of the colony. The eggs in this 

 isolated colony were much further advanced in incubation 

 than others from the cliffs farther east. From Spitsbergen 

 the only positive record is that of one obtained in August 

 1808 on Barents Island by the Prince of Monaco, though 

 possibly one was shot by Herr Dreycr in 1881. 



56. Uria lomvia lomvia (L.). BriinnicVs Guillemot. 

 Breeds in enormous numbers on the cliffs of the south 



coast of Bear Island as already mentioned. In Spitsbergen 

 there are also many large colonies, but it is very questionable 

 whether it is, as stated by Koenig and Le Roi, the commonest 

 kind there excepting the Little Auk, as the Fulmar is much 

 more generally distributed and breeds inland as well as on 

 the coast. 



57. Uria grylle maudtii Mandt. Mandt's Guillemot. 

 Small colonies of breeding birds scattered along the cliffs 



of the southern part of Bear Island, where a bird was found 

 sitting on iaijo eggs on 16 June, 11)21. In Spitsbergen it is 

 widely distributed, ranging north even to Ross Island and 

 Charles XII Island, and it is not uncommon to find several 

 pairs breeding in cliffs a mile or two distant from the sea. 



58. Plotus alle (L.). Little Auk. 



Breeds in sm ill colonies at many points round the southern 

 coast of Bear Island, but not in great numbers. Here we 

 obtained fresh eggs on 16 June, 1921. In Spitsbergen it is 

 much more numerous and is probably the commonest bird, 

 though not nearly so general as the Fulmar. Some colonies, 

 as for example those at Advent Bay and Magdalena Bay, are 

 of enormous extent, and the breeding-range extends north
