Pica pica -- Black-billed Magpie, Eurasian Magpie, pie bavarde. Alternate name on piece: Pica bottanensis [Bootan magpie] Layout drawing, birds fairly well finished; 3 notes on form; money calculations in margin; Sotheran's MS title at foot "Pica caudata?" Presumably the two drawings at Gould item 471, if correctly identified, are preliminaries for this. Artist's name(s): Gould, John; Richter, Henry Constantine.
