Abstract :As the second fascicle, this paper describes five species of Devonian alveolitine tabulate corals from limestone pebbles in Mesozoic conglomerate of the Kotaki area, Niigata Prefecture, central Japan. They are Alveolites sp. indet., Crassialveolites niigataensis Niko, Ibaraki and Tazawa sp. nov., Squameoalveolites sp. indet., Coenites? sp. indet., Planocoenites sp. indet., and Roseoporella? sp. indet. A Middle Devonian species, Crassialveolites tumefactus Tchi, 1980, from North China is most similar to this new species, but they can separate in growth forms of the coralla and presence or absence of the septal spines. Until now, occurrences of Crassialveolites and Squameoalveolites have not been known in Japan.
