Drawing depicting: Eurostopodus guttatus, Uncolored litho print. This is an unpublished form of the illustration. The published plate is in portrait aspect rather than landscape as here, and the setting is changed from a tree branch to a cliff top. Close examination seems to indicate that the image of one bird was drawn separately and then partly superimposed on the other; certainly the position of both birds on a single branch in Gould 2268B is difficult to comprehend. Pencil lines here call for changes to the throat and top of the head of one bird; the changes can be seen in the published plate. Also in pencil: "Turnix = Swift-flying Hemipode / [Piccadilly notes 9:] 799 / [Piccadilly notes] 22/2621 / 5/5/-" (Sotheran's book catalogue reference and price). Previously cited as GS3 or 3GS (and so marked in pencil on reverse).
