(1) The characteristics of pharyngeal bones and their teeth in two genera and seven species of Japanese Acheilognathid fishes are described in this paper. (2) The characteristics of the pharyngeal bones and their teeth in Acheilognathid fishes, as a whole, are summarized as follows: Pharyngeals with prominent anterior angle, breadth 2.5-3.0 in length, length 10-13 in body length of the fish. Teeth only one-rowed, 5, 0, 0-0, 0, 5 in dental formula, moderately compressed, laterally symmetrical, with well developed long and narrow grinding surface. Tips of teeth smoothly, weakly recurved and more or less expanded, with pointed ends. (3) As a substitute for conclusion, the writers have established the following key according to the characters of them, for conveniences in identification. A1 Side of pharyngeal teeth without serrations B1 Length of bone about 12.1-13.0 in body length, breadth of bone 2.75 in length, anterior and posterior edentulous processes equal in breadth……Rhodeus ocellatus (KNER) B2 Length of bone about 11.1-12.0 in body length, breadth of bone less than 2.75 in length, anterior edentulous process broader than posterior one.
