Nymphicus hollandicus -- Cockatiel. Alternate name on piece: Nymphicus novae-hollandiae [Cockatoo parrakeet] Fine watercolor of one bird; color is puzzling, since the tail seems to be that of a male, while the head marking very closely resembles that of the female in the published plate; different composition. Previously cited as GS7 or 7GS, and so marked in pencil on the reverse. Artist's name(s): Gould, John; Gould, Elizabeth. At foot, in pencil "Mrs Gould." Artist credit on published plate: Drawn on stone by J. and E. Gould from a drawing by Edwd. Lear.
