The Least Puffin was not recorded from Japan until it was described 

 from two examples, one of which, in the Tokio Museum, was procured 

 on the Kaga coast of Hondo, and the otter, in the Hakodadi Museum, 

 was caught in Hakodadi Bay in Yezzo (Blakiston and Pryer, Ibis, 

 1878, p. 210). On the 2nd of March, 1883, several examples were 

 collected in Hakodadi Bay by Mr. Henson, two of which were sent 

 me by Captain. Blakiston (Seebohm, Ibis, 1884, p. 31), and two more 

 came into my possession afterwards. 



The Least Puffin breeds in great abundance on the islands in the 

 North Pacific Ocean as far north as Bering Straits, and as far south 

 as the Aleutian Islands.
