The days of big game seem to be numbered. Lists of mammals recently extinct are growing longer and longer and many more species are in danger of extinction. Of course, the last world war has hastened the fate of several species of animals. Eastern Asia and the Pacific region without doubt have suffered most in this respect. For example, the number of Javanese Rhinoceros, Rhinoceros sondaicus DESM., has diminished to such extent that survival seems hardly possible, owing to the aftermath of the Pacific war, which put out of action all painstaking measures of protection. Even before the last war two Asiatic species of deer were on the list of nearly extinct animals, viz. the Milu and Schomburgk’s Deer.
