Pelvic and anal fins pale to yellowish. A faint dark area at bases and axial of pectoral fins. Inside opercle darkish, often visible externally. Mouth large, oblique, lower jaw slightly projecting. Upper jaw with a pair of large canine-like teeth at tip. Lower jaw with a row of widely spaced larger inner-row teeth, gradually increasing in size posteriorly. Chin without barbel or pore, snout with 2 marginal pores. Gas bladder with a pair of horn-like anterior appendages.
