摘要
The chromosomes of 6 spp. of cottoid fishes from Japan are studied. Trachidermus fasciatus and Cottus kazika have the diploid number of 40, the arm-number being 64 in the former, while 58 in the latter. The remaining 4 spp. belonging to the genus Cottus have the diploid number of 48. The arm-number is 58 in C. pollux and C. nozawae, 54 in C. hangiogensis and 60 in C. reinii. The taxonomical relationship between the 48 chromosome group and the 40 chromosome-group are discussed on the basis of the chromosome morphology.
