    • Abstract


      The marine catfish genusArius of the family Ariidae comprising 21 species have been divided into six complexes and three groups based on interspecific relationships and morphometric affinities. In this paper themaculatus complex of four species,viz., Anus maculatus, Arius arius, Arius gagora andArius jella has been critically examined in respect of a selected list of 20 morphological characters based on examination of a large series of examples collected first hand by the authors. The samples have been statistically analysed, and the range of variation in respect of each character as exhibited by each species has been delineated. The probability significance test has been made to establish the interspecific relationship.
