Inland taipan South Wales, and William John Macleay described the same snake under the name "Diemenia ferox" (thinking it was a different species). No more specimens were collected until 1972. 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
Coastal taipan being bitten, but the average is around 2.5 hours. The time between a bite and death depends on various factors such as the nature of the bite and the constitution of the victim. Untreated bites have a mortality rate of 100% as the coastal taipan always delivers a fatal dose of venom (an average bite delivers 10-12x the lethal dose of venom for a human adult male), and medical professionals recommend that victims seek immediate medical attention even for apparently minor bites. Before the introduction of specific antivenom by the Commonwealth Serum Laboratories in 1956, nearly all bites were fatal.
