A paper read by Wallace at the 14 December 1852 meeting of the Zoological Society of London, and published in their Proceedings series for that year. This work is notable for Wallace’s introduction of what is now known as the “riverine barriers” hypothesis of Amazonian species distribution, and for his early admonition that collectors should pay more attention to recording the exact location at which their specimens are taken.
