Drawing on tissue. A more careful drawing of the head in Gould item 2169, with two small toucans perched on a branch drawn over it. The latter are intriguing: there are no birds of this size of life in the Monograph of the Ramphastidae volumes, and only one case of reduced figures in the background. Perhaps this is a reduced-scale layout, but there are probably no other examples in the collection, nor does this grouping resemble any of the plates in the 2 editions of Ramphastides. Artist's name(s): Richter, Henry Constantine[?].
