The Black Brant has already in "The Ibis" for January of last year 

 been shown to occur in the eastern part of the Palsearctic region, as it 

 winters in Northern Japan. 



On the islands visited bj" me it only occurs during the migrations, and 

 even then very sparingly. A young female, the only specimen caught 

 during my stay, was obtained late in fall, when swimming at sea, a 

 little off' the northern shore. It kept company with some individuals of 

 Phalocrocorax pelagiciis, no others of its own kind being seen in the 

 neighborhood. The oesophagus contained green algne and leaves of a 

 Zostera. It was very fat. The measurements are as follows:
