No work on the Quaternary changes in climate, flora and fauna would be complete without reference to Moreau's (1966) and Hamilton's (1982) work on the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Zoologisches Forschungsinstitut und Museum Alexander Koenig.
