Unidentified Pteroglossus sp. ? Aulacoramphus sp. ?

Description

Drawing depicting: Unidentified Pteroglossus sp. ? Aulacoramphus sp. ?, Gould 2036-2041 share a dynamic which suggests the hand of Hart; all 5 include a principal bird perching, or in the case of Gould 2040 flying, in a downward diagonal., Fine tracing on tissue. Principal toucan ca. 18" long (Gould's birds are "the size of life" unless stated otherwise) with a strongly hooked bill (appreciably shorter than that of Gould 2036) rather like Pteroglossus hypoglaucus. 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.
