Calyptogena, DALL, 1891., Type species: C., pacifica DALL, 1891., The superfi-cial feature of Calyptogena reminds me of some species of the Veneridae, howeve-r, considering form the standpoints of hinge teeth and pallial line, the presen-t genus is dealt with Carditidae., This geuus is one of the Nothern Pacific elem-ents., C., pacifica DALL and C., elongata DALL are known from the rather deep wate-r of the Western Coast of Alaska and California, and the fossil species of the former is also known from the Pliocene formation of Los Angels., In the Japanese Islands the present genus has never been known as the living species, however, t-wo species of Calyptogena are reported as the fossil ones., One is C., pacifica DALL which is noted by Y., OTUKA from the Wakimoto Bed of Oga Peninsula, Akita Pr-efecture; another one is C., nipponica OINOMIKADO and KANEHARA from the Usigakub-i Bed (Pliocene) and Kubiki Bed (Mio., -Pliocene) of the Higasiyama Oil-field, Ni-igata Prefecture., In this article the writer reported the occurrence of a great number of Calyptogena pacifica DALL from the Morai Bed (Mio., -Pliocene) of the I-sikari Oil-field, Hokkaido., Urio moraiensis SUZUKI perhaps will belong to the p-resent one.,

Nerinea cf., visurgis is a well known Nerinea in Japan so far as known and was first described by NAUMANN and NEUMAYR from the Torinosu Limestone developed at Torinosu, Togano-mura, Takaoka-gun, Koti-ken., Specimens thought to belong to this form, which were deriverd from the type locality and stored in the Institu-ne of Geology and Palaeontology, Tohoku Imperial University comprise two differ-ent types., As atated in the Japanese text, both types may be easily distinguish-able from N., visurgis from the Upper Jurassic of the Northern Germany., One has smooth flanks of the whorls, while the other is characterized by the presence of two tuberculated hands; new names, naumanni and naumanni neumayri are here give-n respectively, the former seems to be more common in Torinosu limestone develo-ped at Torinosu and its neighbours than the latter.,
