The complete osteology of the laboratory-reared hermaphroditic rivulus, Rivulus ocellatus marmoratus, was described. The skeletal system of this species consisted of more than 430 unit bones classified into 68 kinds. The osteological characters of this species were basically similar to those of the members of the Atherinomomha. The loss of circumorbitals, ectopterygoids, first pleural ribs and intermuscular bones was, however, noticed as the prominent features of this species. Anatomical and systematic implications of the observations were discussed.
