The present paper deals ivit.h the composition of food organisms, the seasonal variations of feeding intensity, and the relationships between the digostive organs and feeding habits of lizard fishes (Saurida tumbil,Saurida wadosquamis and Trachinocephadus myops) collected from South Fujian and Taiwan Bank fishing ground.'The results show thst the three species of lizard fishes bolong to demersal fishes,whioh are carnivorous with cannibalism. The compositions of food organisms of these fishes are rather Simple, whereas they feed chiefly on fish a.nd Cephalopods, and less amount of Macrura, lgrachyura and Stomatopoda. In general, the size of the prey( fishes) increases with the fork lenghh of the predator(Saurida tumbil or S.wadosquamis) It has been shown that those Jizard fishes are feeding throughout the year, and the feeding intensities of Saurida tumbil and S.wadosquamis become higher during the spawning season from March to April. The structures of digestive organs arty adapted to their carnivorous habits w hich Saurida tumbil and S.wadosquamis are similar to each other, and their feeding habits axe more ferocious than that of Trachinocephadus myops.
