Mastacembelus malabaricus Jerdon has long been placed in synonymy with Mastacembelus armatus and Macrognathus guentheri. An examination of the specimens of M. malabaricus collected recently from its type locality in Kerala shows however, that it exhibits many valid differences from its congeners. Jerdon's spiny eel is distinguished from its relative species by having eleven large and conspicuous "X" marks on the mid lateral sides,39- 40 dorsal spines,shorter head, shorter dorsal fin, lengthy base of dorsal fin, lesser pre dorsal and pre anal length and shorter dorsal and anal spines. Meristic and morphometric characters are analyzed well based on the topotypic materials.
