Morphology of two foreign species of tongue soles (Cynoglossidae), Cynogiossus browni and C. senekalensis, was observed based on specimens collected from Kunsan fish market from 1992 to 1994. These species are externally similar to Cynoglossus robustus from Korean coast. But these are quite distincitive from Cynogiossus robustus by interlinear scale rows, body size, other counts and proportional measurements of body. The Cynogfossus browni and C. senegalensis are only distributed in western coast of Africa and commercially imported to Korea through Pusan fish market.
