A srudy on the structures of the pharyngeal bones and teeth in two Korean ricdrishes, Oryzias latipes and O. sinensis was carried out to find out intersoecfic differences. ln the pharyngeal bones, both two species have a pair of upper pharuyngeal bone (stilliform shape)and lower pharyngeal bone(rectangylar shape).ln the lower pharyngeal bones. in paricular,the number of the row was 6 to species :O.latires of a top-hooked type and O.sinensis of a conical type Through this sthdy, we confirmed that the two Korean ricefishes show distntive characteristics in the structure of the pharyngeal teeth.
