ORNITHOLOGICAL EXPLORATIONS. 



Captain Blakiston was correct iu ideutilyiug the birds from Japan us 

 leucopareia, and so was I\Ir. Seebolnn when he afterwards referred them 

 to the true hutchinsii, but he is entirely wrong when saying (Ibis, 1882, 

 p. 369) : "A skin sent (Xo. 2021) i)roves to be of this species {hutchinsii), 

 and not of B. leucopareia. The former has sixteen tail-feathers, with the 

 wing 16 inclies long, whilst the latter is said to have eighteen tail- 

 feathers, with the wing 18 inches long." He evidently confounds /cmco- 

 pareia with B. occidentalis Baird, which, like canadensis, is said to have 

 eighteen to twenty rectrices,(f ) and the wing measuring from 16.25 to 18 

 inches, while leucopareia {=huicMn^ii) has only sixteen tail-feathers, 

 and the wing from 13.60 to 10.35 inches long. I find m Captain Blakis 

 ton's manuscript notes measurement of birds from the Kuriles agree- 

 ing closely with those of true hutchinsii. Mr. Seebohm has apparently 

 been led to make the above statement by not being aware that Baird's 

 leucopareia (B. K. A., p. 765) is the same author's occidentalis, which is 

 difi'erent from Brandt's leucopareia.

Hutchinson's white-cheeked goose is i)robably the only one of the 

 Leucohlepharon group which breeds in the Palsearctic ornis. As already 

 announced in my preliminary report (Pr. U. S. Nat. Mus., 1883, p. 70), I 

 found it breeding in small numbers on Bering Island, where I observed 

 them repeatedly on the large swamp east of the village, and where 

 afterwards an adult was shot and one of the six downy young captured. 

 My hope that the latter might escape being eaten by any of the six 

 hundred dogs of the village was not fulfilled. 



In 18.S3 the first arrivals were announced on the 2d of May, and on the 

 9th of June a male was killed near Saranna.
