There have been many fish scales from the Neogene Tertiary deposits reported in Japan. However, these fish scales have not been studied critically, and only been treated as "fish scale" or "Sardinops sp." From the Bessyo formation in Central Shinano the scales have also been found abundantly. In this paper, we have explained the morphological characters of these scales, especially through the ones. According to our observations, they are divided into 18 types, of which 14 types very nearly coincide with the Recent ones and can be determined of each family or genus, while the other 4 types cannot. The formers are Clupeidae, Coryphaenoididae, Myctophidae, Sparidae. Scombresocidae, Gadidae, Scombropidae, Gobiidae and Halosaulidae. They were found from the drinage area of the Kangawa at Iseyama, Ueda City.
