Gould [John] & Gould [Elizabeth]
Ramphastos Citreopygus. Lemon-rumped Toucan, hand-coloured lithograph, 555 x 380 mm., printed by C. Hullmandel, 1833-35.
***Plate no. 26 from the first edition of Gould’s ‘A Monograph of the Ramphastidae or Family of Toucans’. Gould found out that the specimen he had illustrated was a freak, and so it does not appear in the second edition.
