Pterodroma hasitata -- Black-capped Petrel, Pétrel diablotin. Alternate name on piece: Procellaria hasitata [Great grey petrel] Finished watercolor. As in the case of Gould item 2282, this bird is shown as lightly shaded white, rather than the published gray; however the drawing of the bird is virtually identical to the published form. See Notes to Gould item 2286. The background is changed in the published plate. At lower right "Mrs Gould" in pencil. Previously cited as GS18 or 16GS and so marked in pencil on reverse. Artist's name(s): Gould, John; Richter, Henry Constantine.
