 note = {A Late Miocene freshwater bivalvian shell of Parreysia binaiensis Takayasu, Gurung & Matsuoka, 1995, is examined to assess its state of preservation as well as to determine its shell structure and mineral composition. The characters of shell micro-structure are valuable for their systematics, phylogeny and environmental analysis. It is found that the shell is well preserved with most of the shell layers intact. The X-ray diffraction analysis shows that the mineral species of the shell is wholly aragonite. Shell structure type is typical of a common freshwater bivalve of the family Unionidae, i. e. with nacreous and aragonite prismatic layers.},
