SUMMARY
The chromosome complements of five Indian murrels belonging to the Genus Channa viz. C. striatus, C. barca, C. punctata, C. stewartii and C. orientalis have been investigated. The diploid number and chromosome formula for each of these species have been established. The most interesting finding is the existence of two chromosomal variety of C. punctata with 2n number as 34 and 32. Basing on the present findings, a hypothetical line of karyotypic speciation among the different Channa species has also been presented. Robertsonian rearrangements superimposed with pericentric inversion and/or centromeric shift seem to be the underlying factor in chromosomal speciation in Channids.
