(syn. Somateria Ϯ Spectacled Eider S. fischeri) Gr. αρκτος arktos north; νηττα nētta duck; "I take this opportunity of also exhibiting a beautiful drawing of the Lampronetta Fischeri of M. Brandt (Pl. CVIII.), of which only one example was known to exist in collections, viz. in the Museum of the Academy at St. Petersburgh. Mr. Adams had the good fortune to obtain, not only the male, but the female, during the voyage, as also the young male in change which is exhibited in the smaller drawing. ... I may observe that Mr. Adams had called the species, from the rich blue colour of the eyes, "Blue-eyed Eider Duck." As M. Brandt's subgeneric name of Lampronetta is so near Lampronessa of Wagler, it may be thought advisable to change it to Arctonetta." (G. Gray 1856).
