Two principal toxins from venom of the sea snake Laticauda semifasciata have been purified and their amino acid compositions studied previously. Tamiya and Arai 1966, working with venom obtained from sea snakes collected in Okinawan waters, called the two toxins Erabutoxins a and b amino acid compositions and sequences of the two compounds were reported by Sato and Tamiya 1971. Tu et al. 1971 obtained two similar toxins, called Toxins a and b, from the same species of Laticauda collected in Philippine waters results of their amino acid analyses are somewhat different from those of Sato and Tamiya. In the present paper the authors report results of studies made on the two principal toxins obtained from cenom of Laticauda semifasciata collected in Taiwan. The results are in complete agreement with those of Sato and Tamiya.
