16. CoLYMBUs ADAMsi, G. R. Gray. 



The skin sent (No. 134^9) is the Black-throated Diver, C. 

 arcticus, Linn. There is, however, no reason to suppose that 

 Swinhoe was wrong in his identification of C. adamsi (Ibis, 

 1877, p. 146). The latter bird is a form of C. glacialis, with 

 a white bill, found in Siberia &c., and probably entitled to 

 specific rank. 



23. Anser erythropus, Linn.? 



In the Swinhoe collection is a skin (No. 2007), a female, 

 dated "Tokio market, Jan. 1876," which is unquestionably 

 Anser erythropus. The wing from the carpal joint measures 

 15i in. Two females of A. erythropus, from the Yen-e-say, 

 measure respectively 13^ and ]3|. These measurements are 

 made wath a tape across the upper surface of the wing.

In Swinhoe's collection are two skins of the Mallard from 

 Hakodate, (No. 1190) a male and (No. 1717) a female.

In Swinhoe's collection are two skins from Awomori, (No. 

 1183) a male and (No. 1185) a female. 



36. QUERQUEDULA CRECCA (L.). 



In Swinhoe's collection are two skins from Yesso, (No. 

 1444) a male and (No. 1719) a female. 



39. QuERQUEDULA FORMOSA (Gcorgi) . 



In Swinhoe's collection are two skins, (No. 1180) a male 

 from Anoraori and (No. 1981) a female from Yeddo. 



43. FULIGULA CRISTATA (L.) . 



The skin sent (No. 2266) is a male, in full breeding-plumage, 

 of the Tufted Duck, Fuligula cristata (Leach) . 



45. Fuligula nyroca (Gm.). 



The skin sent (No. 45), from the Yokohama market, appears 

 to be correctly identified. It is an immature male of Nyroca 

 ferruginea (Gm.). 



47. Clangula histrionica (L.). 



In Swinhoe's collection are two skins, (No. 1449) an im-
