鹿児島県上甑島浦内湾の現生底生有孔虫群

The distribution of benthic foraminifera in Urauchi Bay was investigated to learn bay foraminiferal occurrence along the eastern part of the East China Sea. Ammonia sp. A, Ammonia beccarii forma 2, Pseudorotalia gaimardii compressiuscula, Pseudononion japonicum, Nouria textulariformis, Frusenkoina compactiformis and Nummulites ammonides are common constituents of the living（stained）foraminiferal assemblages in Urauchi Bay. These faunal associations are similar to those of Kagoshima and Tanabe Bays. Ammonia sp. A and A. beccarii forma 2 occur in the shallows of the inner parts of the bay, whereas P. gaimardii compressiuscula is common in the deep part of the middle to the outer parts of the bay.
