Rivoli Bay before sunrise (top); Penguin Island off Rivoli Bay (bottom). Part of the text accompanying the top illustration reads 'Rivoli Bay is situated in S. latitude 37 degrees 30'; although open to the S.W., a natural breakwater is formed by reefs that stretch across the entrance to the bay ... The accompanying sketch represents the moon setting in the rose-coloured reflection thrown by the rising sun upon the western sky'.

For Penguin Island (bottom) Angas noted '... Penguin Island, so named for those birds which inhabit it, and breed amongst its rugged and sea-worn shore. The entire island is perforated with thin burrows ... The seaward extremity of this rocky island is so perforated and fretted away by the action of the elements, as to present a very curious appearance. The circumference of Penguin Island does not exceed three quarters of a mile'. Both these sketches were completed during April/May 1844.
