Mitotic and meiotic chromosomes prepared from specimens of Ichthyophis italics tricolor collected from either side of Palghat Gap from three different locations of Western Ghats revealed a diploid number (2n=42-44) with Fundamental Number (62-64). Highest diplod number (44) and occurrence of chromosomal polymorphism is documented for the first time for gymnophion amphibians. Role of chromosomal rearrangements involved in karyotypic derivation process is discussed.
