Abstract: The large-sized sardines taken from the west and north coasts of Kyushu in 1951 were compared with each other and with other past samples from various localities, applying the R.C.R.L. by 5 characters formerly reported and x2 test of vertebral number. The results from the R.C.R.L. agree well with those from body-length and maturity, but not so much with those from vertebral number. Namely, Samples except from Saga (1), Tsusima, Nomo (3) and Ojika are intimately related with each other. My samples belong to 4 in 5 groups of the large-sized from Kyushu reported by Seikai Regional Fisheries Research Laboratory sampled at the same fishing season according to the modes of body-length frequencies. The groups excluding those having the modes of 20 cm show markedly lower vertebral number (50.524) than that of the past "All Japan" (50.674, 1933-1938), indicating that the greater part of this spawning sardine might have been originated at higher water-temperature than the past or other.
