The Thayer Expedition was a scientific endeavor sponsored by Nathaniel Thayer Jr.. It was an ecological and biological expedition undertaken by multiple scientists in 1865 and 1866, and resulted in various type specimens that were later recognized as new species by those that had attended.[1] This expedition took place at the end of the American Civil War, the initial voyage from New York to Rio de Janeiro beginning in the war's final week.
