than in any other. After keeping it with us day by day from New Zealand eastward 

 to 144° W. 55° S., we suddenly and completely lost it, nor did we see it again during 

 the remainder of that voyage. Its burrow, according to Mr. Eaton, is short and 

 generally excavated in Azorella ; it is as large as a rabbit's hole, dry, and with its 

 entrance bestrewn with green shoots of Accena. It l)reeds on the Kerguelen Islands.

 and E. long. 140° on November 16th and 17th, 1901. But it was not until January 

 2nd, 1902 that we saw the bird in numbers, and then during the summer, cruising 

 along the coast of South Victoria Land and the Barrier to King Edward VII. 's Land, 

 it rarely failed to keep us company. Nothing could be more beautiful and less appa- 

 rently fitted for the rigours of a storm-ridden climate, such as the Antarctic, than this 

 little dove-like bird. It is the most constant companion of the ice, and whereas we saw
