Finished watercolor study of one animal, not very close in pose or specifics to the published plate; note in lower right corner, hard to read: "Kangaroo Eul[?] / Paris / aussi grand que"; financial calculation. Gould's text relates that the two animals in the plate were taken from specimens in the Paris and Leyden museums (cf. Gould item 745). Artist's name(s): Richter, Henry Constantine.
