Three bivalve species collected from the Permian H. S. Lee Formation at the H. S. Lee No.8 Mine in Perak, Malaysia are described. They are identified as Sanguinolites ishii sp. nov., Megalodon (Megalodon) yanceyi sp. nov., and Myalina (Myalina) cf. wyomingensis (Lea). The fossil locality is famous for the abundant occurrence of gastropods together with bivalves, cephalopods, calcareous algae and others, but is flooded and inaccessible now. The new species of Megalodon is considered to be the first record of the genus in the Permian.
