Referee's report by William Henry Flower, on a paper 'On the ova of the Echidna hystrix' by Richard Owen Recommended for publication in the Proceedings of the Royal Society of London, due to its short length, but as it forms part of a series, the author may wish for it to be published along with the other memoirs in the Philosophical Transactions, to which the referee has no objection. Subject: Zoology [Published in the Philosophical Transactions of the Royal Society, 1880] 10 August 1880
