Notes

1. Plankton collections were made in Korea at 16 places, which may be classified roughly into four regions-the northen, western, middle, and eastern. 2. Fifty-eight species of Rotatoria were identified in these collections. In addition, seven species can be added from previous records. With the addition of eight varieties and seven forms, plus three undeterminable species, the total number becomes 83. 3. The species of wide distribution are Keratella cochlearis and Polyarthra trigla, both including several varieties or forms. 4. Species of Brachionus were found only in a few stations.
