Dromaius is a genus of ratite present in Australia. There is one extant species, Dromaius novaehollandiae commonly known as the emu.In his original 1816 description of the emu, Louis Jean Pierre Vieillot used two generic names; first Dromiceius, then Dromaius a few pages later. It has been a point of contention ever since which is correct; the latter is more correctly formed, but the convention in taxonomy is that the first name given stands, unless it is clearly a typographical error.
