Abstract: 1. As the 0-year sardines caught in 1952 from the west and the east coasts of Kyûsyû are the same types of AP analysed by χ²method, it may be necessary to classify into smaller types of vertebral compositions in order to compare with each other or to compare mutually each shoal from the west coast. 2. To classify smaller types there are 4 methods of χ²comparison, but one of them only is used here on account of the lack of full discussions. 3. As the results, the composition of types of samples in 1951 differs remarkedly with that in 1952, namely, the types of both coasts of kyûsyû in 1951 are different remarkably each other, but those in 1952 are nearly the same. / 1.X2比較法に依つて脊椎骨組成を小類型に分ける事により,或は小範囲の魚群の洞游(移動) を推定し得るか否かを吟味するため,既報の類型及び昭和27年産の類型より小類型を組分けした。 2.組分方法は標本対標本のX2値に依つたが,他の3方法には今後解決すべき点が残つている. 3.結果としては,昭和26年産と27年産とは著しく小類型の組成が異る。叉26年には東岸に大差あり,西岸には小類型2,東岸には小類型3大類型他1であるが727年には東西岸大差なく,西岸には小類型2,東岸には小類型1であつた.
