To the Zoological Society of London a plan published in its Proceedings for that year (pp. 46-48), and reprinted also in his own journal The Zoologist (pp. 2780-2782), based on exactly the same considerations, dividing birds into two groups, " Hesthogenous "- a word so vicious in formation as to be incapable of amendment, but intended to signify those that were hatched with a clothing of down - and " Gymnogenous," or those that were hatched naked.
