ResumoThe chromosomes of two Nandid fishes, viz., Nandus nandus and Badis badis from India have been studied. N. nandus has a diploid count of 48 chromosomes with NF=84, while B. badis possesses 2n=46 with NF=52. The haploid chromosome formula worked out for N. nandus is n=2m+9sm+7st+6t, while for B. bodis, it is n=3m+20t. Certain mitotic and meiotic polyploid cells from testicular material have been recorded in both the species. The sex chromosomes could not be distinguished in either of the species. The cytotaxonomical relationship between family Nandidae and suborder Anabantoidei (order: Perciformes) has been discussed.
