The 46 names of species of marine bivalves and gastropods made available by Grabau & King in 1928 are discussed. Probable or possible type material for all but 13 of these taxa has been located in the Institute of Oceanology, Chinese Academy of Sciences. Of these taxa, nine are regarded as valid, the rest being junior synonyms. The valid taxa are: Verilarca interplicata, Collisella peitaihoensis, Rissoina barbara, Rissoina bureri, Epitonium scalare minor, Gradatiscala gradata pygmaea, Nassarius gregarius, Terebra bellanodosa and Mangelia dobsoni, all Grabau & King, 1928.
