of some of the great bird-colonies and some notes on the 

 changes in the fauna during the last 25 years were also given. 

 One of the great oological successes of the trip was the 

 acquisition of no fewer than 22 eggs of Branta leucopsis. 

 Of this species only 12 authentic specimens of the eggs 

 have ever previously been obtained from wild birds. Other 

 interesting eggs taken were those of Fratercula a. naumanni} 

 Somateria spectabilis, Uria grylle mandtii, etc.
