Caudal ends in a hardened point. Ogivale head, small eyes near buccal joint at end of snout. Buccal slit short, snout prominent covered with villi. Gill slits lateroventral, crescentiform. Thin dorsal and anal fins, in groove; dorsal origin behind gill slits (predorsal length 11.5-16.9% TL); anal origin immediately behind anus. Pores of lateral system and cephalic slightly rimmed.
