Following the 1st Report on the results of analyses of aqueous extract of a shellfish, Venerpis Semidecussata Reeve, the residual meat (muscles and internal organ) were cut into fine pieces, digested with water, and its aqueous solution analysed. The amount of nitrogen-containing compounds other than volatile amines and arginine in this water solution was less than that of the extract reported previously, especially in the amount of taurine, glycocoll betaine and monoamino acids. Compounds detected in the aqueous solution were: ammonia, trimethylamine, xanthine, adenine, hypoxanthine, arginine, glycocoll betaine, histidine, guanine, tyrosine, taurine. N-Methylpyridinium hydroxide was not detected. Unknown bases obtained were one from the lysine portion giving an aurate of m.p. 138-140°, and one from arginine portion giving a picrate of m.p. 222-225°, which was found to be identical with the one from the aqueous extract reported previously.
