• The mitotic and meiotic chromosomes of Phagocata vivida were observed by the air drying method in the neoblasts of regenerating pieces and primary spermatocytes and oocytes, respectively. The chromosome number of this species was determined as 2n=36 or 36+1 B in somatic cells and n=18 or 18+1 B in germ cells. The karyotype consisted of 8 pairs of metacentric chromosomes and 10 pairs of submetacentric chromosomes. Chromosome No. 11 had a satellite at the end of the long arm. The karyotype of this species distinctly differed from those of four Japanese species; Ph. teshirogii, Ph. Kawakatsui, Ph. Papillifera and Ph. Suginoi, although it was common to all the five Phagocata species that chromosome No. 1 was extremely large and metacentric.
