Gills tufted, not laminated, composed of small rounded lobes attached 
to the gill-arches. Scapula suspended to the cranium by a iiost-tem- 
poral. Superior branchihyals and iiharyngeals, and basal branchi- 
hyals wanting or not ossified. Mouth very small, bounded above by 
the premaxillaries. Post-temporal simple, co-ossified with the cranium ; 
basis of the cranium simple. Pectoral fins with elevated bases. Inter- 
clavicles well developed. Anterior vertebrae modified, the diapophyses 
much expanded. Air-bladder simple, without- air-duct. Snout pro- 
duced, bearing the small toothless mouth at the end. Gill-covers re- 
duced to a large simple plate. Skin with bony jdates. Muscular
