Description: Relatively deep-bodied, with steep back and deep caudal peduncle (Ref. 52193). Mouth large, with 2 pairs of barbels (Ref. 52193). Dorsal fin with 3 spines and 8 soft rays; anal fin with 3 unbranched and 5 branched rays; third simple ray enlarged to form a stout spine with serrated posterior margin, longer than head length (Ref. 13337, 52193). Scales in lateral line 30-34, 16 around caudal peduncle (Ref. 13337, 52193). Colouration: Silvery in life (Ref. 52193), with no trace of black pigmentation (Ref. 13337). A faint lateral stripe appears in preserved material which somehow appears to maintain a silvery sheen (Ref. 13337). |
