Drawing on tissue. 2 toucans circa 14" long (Gould's birds are "the size of life" unless stated otherwise) with a strongly hooked bill. Not found in the published editions of the Monograph of the Ramphastidae, or family of toucans. What the purpose of these drawings may have been is unclear; perhaps Gould intended a further revision and extension of the work. Gould items 2036-2041 share a dynamic that suggests the hand of Hart; all 5 include a principal bird perching, or in the case of Gould items 2040 flying, in a downward diagonal.
