1. Chromosomes of five tetraodontiform fishes (Lactoria diaphana, Ostracion immaculatus, Canthigaster coronata, Fugu pardalis, Fugu poecilonotus) were observed, and the structural morphology of the relation between the axial skeleton and pterygiophores of 102 species in Tetraodontiformes was reported. 2. Phylogenetic systematics of tetraodontiform fishes were studied on the basis of karyotypes and osteological characters by a newly revised method of WAGNER's (1969) groundplan/divergence method. By analysis of 17 osteological characters, living tetraodontiform fishes were classified into 6 families (Triacanthodidae, Triacanthidae, Balistidae, Ostraciidae, Triodontidae and Tetraodontidae), although the systematic position of a monophyletic group corresponding to Molidae sensu TYLER (1980) was left for a future study. Among above 6 families, phylogenetic classification of Balistidae, Ostraciidae and Tetraodontidae was constructed after phylogenetic interrelationships in above 3 families were reconstructed. On the basis of 12 osteological characters and karyotypes, 63 species of Balistidae were classified into 2 subfamilies, Balistinae and Monacanthinae. Balistinae was considered to be ancestral to Monacanthinae which consists of 3 tribes. On the basis of 11 osteological characters and karyotypes, 17 species of Ostraciidae were grouped into 2 subfamilies, Aracaninae and Ostraciinae. Aracaninae was considered to be ancestral to Ostraciinae which was separated to 3 tribes. On the basis of 9 osteological characters, the nasal apparatus and karyotypes, 48 species of Tetraodontidae were classified into 3 subfamilies, Liosaccinae (nov.), Lagocephalinae and Tetraodontinae. Tetraodontinae was classified into 5 tribes, one of which corresponds to Diodontidae sensu TYLER (1980).
