背棘 (總數) : 0; 背的軟條 (總數) : 11; 臀棘: 0; 臀鰭軟條: 9 - 11; 脊椎骨: 37. Flexible, unbranched first ray and ten branched rays on its dorsal fin; dorsal fin situated relatively far posteriorly; pterygiophore of anterior dorsal fin ray articulating with neural spine of tenth vertebra; blade like neural spines of vertebrae five through nine extend dorsally, diverging at their dorsal ends to form a double row of ossifications just ventral to skin between supraoccipital and dorsal fin origin; a slender supraneural at posterior end of this v-shaped predorsal trough has attached muscles extending anteriorly between bifid neural spines to supraoccipital; maxillary barbel very long , reaching posteriorly beyond anal fin base. Distal portions of dorsal, adipose and anal fins, and most part of caudal fin almost unpigmented.
