Of the plankton collected by myself at 72 stations located in the South China, Java, Celebes, and Sulu Seas, the Macassar Strait, and the part of the Indian Ocean off the Sunda Strait on board the research boat, Shonan-Maru of the Formosa Gervernment, the pelagic Ciliata, suborder Tintinnoinea, are dealt with in the present work, with the following results: - 1. 39 species of the Tintinnoinea belonging to 16 genera have been detected from the materials, and of those two seem to be new to science. 2. All species recorded in the present paper are forms of warm or tropical waters. However, some are cosmopolitic and occur even in cold waters. Occurrence of neritic species is generally superior to that of oceanic ones in the seas of the East Indies. The plankton in the deep area of the South China Sea, and in the Celebes and Sulu Seas is oceanic, and that in the shallow part of the South China and Java Seas, and the region of the Indian Ocean near the Sunda Strait is neritic, while the plankton of the Macassar Strait and the deep area of the Java Sea is intermediate in character. 3. The inflow of surface water of the Java Sea into Indian Ocean through Sunda Strait can be inferred from the distribution of plankton. Poroecus rotundatus n. sp. (Fig. 2). Lorica stout cup-shaped, 1.1 oral diameters in length; aboral end hemispherical; wall with a rough surface resulting from coccoliths attaching to the orica. Length, 40μ; oral diameter, 36μ. Locality-Macassar Strait. Differs from all the other published species of this genus in the small stout lorica and in the hemispherical aboral region. Craterella retusa n. sp. (Fig. 3). Lorica small, ovate, having two collars, 1.1 oral diameters in length; inner collar comparatively high, curved; outer one low, spreading conically (84°); aboral end rounded; wall thin, hyaline. Length, 33μ; oral diameter 30μ. Locality-Off Surabaya, Java. Differs from all other species of genus Craterella in the stout ovate form.
