About 400 subsamp1es from seven cores collected from a samp1ing profi1e located west of the coast of Laizhouwan，Bohai were qualitative1y and quantitative1y analyzed for their foraminifera1 contents with the aim of determining the distribution of marine and continental facies and of finding fauna1 evidence of marine transgressiveregressive sequences requisite to an understanding of the depositiona1 environment of the area, A tota1 of 93 benthonic foraminiferal species belonging to 14 families and 36 genera is identified. Two genera and fifteen species are new. A comparison of these species with the Recent foraminiferal fauna of Bohai shows that although there is a marked difference in species composition (only 51 species are in common with those of Bohai) , there is a marked similarity in faunal characteristies，with the majority of the species belonging to the temperate fauna. However, there a1so occur a few warm water species such as Elphidium simplex Cushman, Pseudorotalia schroeteriana(Parker and Jones) ， Asterorotalia pulchella (d 'Orbigny),etc.，which are non-existent in the Recent fauna of Bohai. The occurrence of these warm water species provides a basis for interpretating the paleotemperature of the sea water as being slightly warmer than that of the present day Bohai.
