Chromosomes of cyprinid fishes have been studied more intensively than those of any other family of fishes except the family Cyprinodontidae (VASILIEV, 1980). As regards Japanese cyprinids, chromosomes of 20 genera and 35 species-subspecies have been hitherto reported (OJIMA & HITOTSUMACHI, 1967; OJIMA et al., 1970,1972,1973,1976; ITOH & NIIYAMA, 1972; KOBAYASI et al., 1970,1973a, 1973b; ARAI & FUJIKI, 1977). As I had the chance to observe chromosomes of two cyprinid fishes, Acrossocheilus labiatus from Taiwan and Pseudorasbora pumila pumila from Japan, their karyotypes are here described. As regards Eurasian cyprinid fishes, karyotypes of 58 genera and 141 species-subspecies have been reported, including those of two species in this paper. Their karyotypes are reviewed in this paper and phylogenetic systematics of Eurasian cyprinid fishes are discussed on the basis of karyotypes and several morphological characters. Method of chromosome preparation is the same as that of ARAI (1973). Classification of chromosomes is adopted from LEVAN et al. (1964). Metacentrics and submetacentrics are described as two-arm chromosomes, and subtelocentrics and acrocentrics as one-arm chromosomes. The definition of the new arm number (NAN) is referred to ARAI and NAGAIWA (1976). All the specimens used for the experiments are deposited in the fish collection of the Department of Zoology, National Science Museum, Tokyo.
