Referee's report by Edwin Ray Lankester, on a paper 'The prehensores of male butterflies of the genera Ornithoptera and Papilo' by Philip Henry Gosse Recommended for publication in Philosophical Transactions. Usually a paper like this would be better off printed in a Zoological Society publication, but it merits a place in a Royal Society publication. Subject: Zoology [Published in Proceedings of the Royal Society, 1881]. 16 January 1882
