Notes

1. An attempted zoogeographical sketch of the inland water fauna of the Island of Taiwan (Formosa) is based chiefly on the microfauna especially on Copepoda, Cladocera and Rotatoria. 2. The greatest number of endemic genera and species is found in the Copepoda especially in the Cyclopoida, while in both the Cladocera and Rotatoria no endemic forms are found. 3. Considering the above groups of animals, the inland water fauna of Formosa exhibits a great degree of faunal similarity to that of the Asiatic continent particularly the Indo-Chinese mainland and Manchoukuo. It is also characterized by the advancement of tropical elements which range over the Malayan region, but they appear to be restricted to the lower districts in the southern half of the island. Cold-tolerant forms of probable northern origin are driven to the high mountain districts. 4. The distribution of most species in the island is greatly restricted by the temperature and chemical nature of the water, especially by the carbonate of lime content.
