Priority! recommends using 1853 for Amaurornis.
Proving beyond doubt that Gallicrex was published in 1852 is probably not easy either, actually... (The date specified in the work is 1849. There is evidence that this is not correct, and that the book was not published in the sense of the Code before Sep 1852. But not much more...)
