To clarify taxonomic status of two forms (Awajichihiro and Yaminonishiki) of Hirase's scallop Volachlamys hirasei, shell morphology was examined as the first report of a series of studies. There were significant differences in morphometrics between the two forms. Relative shell height in the Yaminonishiki form tended to be longer than that in the Awajichihiro form. Relative shell width and shell weight in the Awajichihiro form tended to be larger than that of the Yaminonishiki form. Number of radial costae in the Awajichihiro form tented to be more than that of the Yaminonishiki form. Further, composition of shell coloration was significantly different between the two forms. Although the results could support the view that the two forms should be regarded as subspecies, the conclusion should be given after sufficient examination on the other characteristics.
