Spectacled Petrel. Two birds, the foremost carefully drawn, shaded with light gray wash, the bill and one foot colored to finish standard. The second bird more sketchy and with marks of change. In the published plate the positions are retained, but the birds are dark brown, are both on land (rather than the foremost being in the water), and there is no blood dripping from the bill of the foremost. The lack of coloring was probably intended to preserve the intricately drawn feathering for transfer to the stone--and this may well be the case for Gould item 2283 to 2285 also. At lower left in pencil "Mrs Gould." Previously cited as GS22 or 22GS and so marked in pencil on reverse. Artist's name(s): Gould, John; Richter, Henry Constantine.
