Dasyurus geoffroii -- Western Quoll. Alternate name on piece: Dasyurus geoffroyi [Geoffroy's dasyurus] Layout drawing. Multi-line sketching, still at an early stage. Artist's name(s): Gould, John; Richter, Henry Constantine. Logically it has to be by Richter, and indeed it is one of the few signed on the stone by him, but the style is unusual. Perhaps this is one which was not developed directly from a sketch by Gould.
