In my notes, I have:

Note: Gray misspelled the type species name ‘
flavirostris’ in the designation. (This does not affect the validity of the designation.) Peters 1934
https://www.biodiversitylibrary.org/page/14482995 claimed a type fixation by monotypy of "Rallus niger Gmelin (not of J. F. Miller) = Gallinula flavirostra Swainson.”
Available: yes
Family: Rallidae
corax, -acis (Latin) = κόραξ, -ακος (Greek) = raven.
Limnocorax was indicated in the OD as "ex λίμνῃ et κόραξ", thus as formed from the Greek version -- this matters little, however, as the word is exclusively masculine in both languages. It was originally treated as masculine, being combined in the OD with the masculine adjective
mossambicus.
