Abstract

The epicranial bony system of the six species of the family Cynoglossidae were examined based on the specimens collected from the coast of Korea from 1992 to 1994. They were divided into four groups by the morphological features of epicranial bony system as follow: 1. Paraplagusia japonica, 2. Cynoglossus joyneri and C. robustus, 3. C. semilaeuis and C. abbreuiatus, and 4. C. interruptus. Among them, P japonica showed the most derived character in the erisma and frontal elements of the epicranial bony system. And it was remarked that the number of proximal radials supporting erisma show much differences among the species. It is discussed that the morphological differences in the epicranial bony system are significant character for interspecific relationships in family Cynoglossidae.
