External morphology of three species of damselfishes, Chromis notata, C. analis and C. fumea were studied based on the samples collected from the Korean waters from 1993 to 1994. In morphology of the black spot at base of pectoral fins, C. notata has a large triangluar spot at Cheju population and a small circular spot at Sin - am. In the length of pelvic fin, C. notata of Korea can be classified into 3 groups. First group has a pelvic fin that extends to the origin of anal fin, second extends to the anus, third not extend to the anus. C. analis has higher body depth than C. notata and C. fumea in % of standard length. C. fumea has a minute serrate preopercle and no black spot at base of pectoral fins. In distribution, C. notata has a more widly distriubtion area than C. analis and C. fumea. Therefore, C. notata has more tolerance of cold waters than C. analis and C. fumea.
