The suborder Percoidei is the largest among 12 suborders of perciform fishes. It contains 72 families, 595 genera and about 3935 species (NELSON, 1976). This suborder is considered to be the most basic in the order Perciformes. However, interrelation-ships of percoid fishes are so complicated that construction of their phylogenetic tree is very difficult. Although there are so many families in the suborder Percoidei, karyological studies on percoid fishes are very poor except on some families such as Centrarchidae, Percidae, Chaetodontidae, Cichlidae and Pomacentridae (VASILIEV, 1980). As we observed chromosomes of six species of percoid fishes from Japan, i. e., two species of the family Kuhliidae, one species each of the family Gerreidae, the family Leiognathidae, the family Chaetodontidae and the family Embiotocidae, we describe their karyotypes and discuss relationships between karyotypes and morphological characters in some percoid families. 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, 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.
