Pins small, with very large fulcra ; dorsal fin short, opposed to the space between the pelvic pair and the anal ; caudal fin symmetrical, slightly forked. Scales rhombic, smooth or feebly ornamented, the dorsal ridgeseries inconspicuous ; the scales of the flank not much deeper than broad, and those of the ventral aspect nearly equilateral"
