 However, for over two centuries, taxonomists believed Valenciennes' account matched the great hammerhead, which thus became known as "Zygaena" (later "Sphyrna") "tudes".The smalleye hammerhead was known by a different name, "Sphyrna bigelowi", coined by Stewart Springer in a 1944 issue of "Journal of the Washington Academy of Sciences".In 1950, Enrico Tortonese examined the Nice and Cayenne specimens of "S. tudes" (the Coromandel specimen having been lost in the interim) and concluded that they were not great hammerheads, but rather the same species as "S. bigelowi".
