 note = {In June 1900, YOSHIDA Otohiko submitted his dissertation thesis of the title “Report on Geology of the Southern Part of Higo” to the Department of Geology in the University of Tokyo. He discovered well-preserved radiolarian fossils in siliceous slates near Ohira village of Itsukimura, identified them as Cenosphaera gregaria (?); Lithocampe aptycalphila (?); Spongodiscidae sp.; Rhopalastrum sp.; and Sphaerozoum sp.; and depicted their fairly detailed figures. YOSHIDA considered the radiolarian fossils to be Palaeozoic, because the radiolarian slates were accompanied with Fusulina-bearing Palaeozoic limestones.},
