6%; dorsal ray 4; anal ray 4; pectoral 2%; ventral 2;

Body short, compressed, the back elevated, its greatest 
depth just in front of spinous dorsal. 
Head large, as long as the rest of the body; snout long 
and narrow; mouth U-shaped, its gape longer than wide, 
lips thick, their surface broken up into papilla; maxillary

large bony ridges above, continuous with the orbital rim 
and ending in strong blunt spines at occiput, head deeply

bony ridge leads to each of these spines; a long sharp 
spine on clavicle just behind gill-opening; a blunt bony 
knob at posterior end of mandible; gill-openings extend-
