212 Messrs. Blakistou and Pryer on 



19. Cygnus bbwicki^ Yarr. " Hakucho." 



Many Swans are seen in the Sliimosa lakes^ probably of 

 several species. A specimen in the Kiyoiku Hakubutsukan 

 agrees with the figure and description of Bewick's Swan 

 in Morris's ' British Birds.' 



20. Anser segetuMj Gm. " Hishikui." 



There are two forms, a large and small, possibly separable. 

 (Swinhoe, Ibis, 1875, p. 456.) 



21. Anser brachyrhynchus, T. ''Magan." 



Common in winter in Tokio Bay, and collected in Yezo, 

 (Swinhoe, Ibis, 1875, p. 456.) 



22. Anser albifrons, Gm. ^' Karigane." 



Also common in Tokio Bay ; seen as early as the beginning 

 of October. Passes Hakodate in spring and autumn. (Swin- 

 hoe, Ibis, 1875, p. 456, et 1877, p. 146.) 



23. Anser erythropus, Linn. ? " Ko-karigane." 

 Obtained in Tokio and Yezo. Specimens sent to Mr. 



Swinhoe, were identified as being the same as the foregoing, 

 which may prove to be an error, owing to a wrong specimen 

 having been forwarded. 



24. Anser cygnoides, L. " Sakatsura-hishikui." 



As in A. segetum, there are two sizes of this bird, which 

 may prove to be distinct. 



25. Anser hyperboreus. Pall. '' Hakugan." 



Arrives in large flocks in winter about Susaki, Tokio Bay. 

 No specimens have yet been sent to Europe for identification. 



26. Anser albatus, Cassin, " Ko-hakugan." 



The smaller birds mixed with the flocks of A . hyperboreus 

 may be of this species. 



27. Bernicla leucoparia, Brandt. " Shijukaragan." 

 Only one obtained, at Hakodate ; not much doubt about 



the species. 



28. Bernicla torquata, Jenyns. " Kokugan." 

 Observed in the Yokohama game-market. The winter 



Sea-goose of Hakodate.
