The chromosome of Anodota woodiana in the Lake Uiam was analysed as using air drying technique of spermatogonial tissue to obtain mitotic and meiotic chromosomes. The chromosome chcle did mot differ, in general, from that found in other bivalves. Chromosome of this species consisted of metacentrics and submetacentrics. The longest chromosome was 2.1 <TEX>${\mu}{\textrm}{m}$</TEX> and the shortest was about 1.4 <TEX>${\mu}{\textrm}{m}$</TEX> in length.
