The present report describes 26 definite species and two species indeterminata of ostracodes from the Toukoshan Formation, Miaoli district, Taiwan. They are Bairdia obtusa, n. sp., Biardia var. taiwanensis Hu & Cheng, Uroleberis ovatus, n. sp., Eucytherura maculata, n. sp., Bosquetina carinata, n. sp., Perissocytheridea oblonga Hu, Loxocorniculum crispatum, n. sp., L. malacrispatum, n. sp., Loxoconcha var. tata, n. var., L. tata, n. sp., L. orientalica, n. sp., L. pleistocenica, n. sp., Loxoconcha sp., Reymontia taiwanica Hu, Parakrithella oblongata, n. sp., Krithe obesa, n. sp., Cushmanidea transversa, n. sp.,Hermanites subtropicus Hu, H. simplex, n. sp•., Semicytherura cf. rhombea Hu, Nipponocythere punctata, n. sp., Cytherura minucostata, n. sp ., Ambocythere sp., Paracytheridea wawa, n. sp.,P. minuta, n. sp., Nearocytherura taiwanica, n. sp. These ostracodes are ecologically separated into six different biotopes, namely estuarine, lagoonal, interlittoral, sublittoral, rocky bar or bioherm, and allogenic biotopes. The ostracode evidence would indicate that the Toukoshan Formation in the Miaoli region was deposited in shallow water about 20m in depth, brackish to normal marine, with salinity varying from 0. 7-3 8.0 o/oo, and the paleotemperature from 18°-28°C in yearly average, which may not be any lower or higher than that of the modern period. The ostracode thanatocoenoses were derived from their localities of origin either by oceanic or along shore currents.
