Teeth bands broad without gasps between teeth rows; teeth small, inconspicuous, multiserial, forming broad continuous bands on jaws and vomer; vomerine tooth-band extending as far back as bands of upper jaw but more pointed posteriorly (Ref. 4832, 52193). Colouration: Dorsal body colour uniform (Ref. 79840). Olive to dark bluish-brown dorsally, lighter ventrally from jaw to anus (Ref. 3971, 52193). Mature adults change to bronzy silver (Ref. 52193). |
