In 1896 George Albert Boulenger classified both as belonging to the same genus, "Pseudechis" (black snakes), referring them as "Pseudechis microlepidotus" and "Pseudechis ferox". In 1956, relying only on published descriptions and notes, James Roy Kinghorn regarded "ferox" as a synonym for "microlepidotus" and proposed the genus "Parademansia". In 1963 Eric Worrell considered "Parademansia microlepidotus" and "Oxyuranus scutellatus" (coastal taipan, named simply "taipan" in those days) to be the same species. In
