b. Cranium not twisted so that both eyes of the adult are on same side 
of head. 
c. Spinous dorsal not modified into a lamellated sucking-disk on top 
of head. 
d. Ventral rays graduated from outer which are longest, and 
inner shortest. 
e. Ventrals abdominal. 
f. No spinous fins; lower pharyngeals co-ossified; lateral 
line on side of abdomen; air-vessel without duct in 
adult. SYNENTOGNATHI 
ff. A separate spinous dorsal and other fins with spines; 
lower pharyngeals not co-ossified; lateral line median 
or obsolete. PERCESOCES 
ee. Ventrals sub-abdominal when present. 
g. Gills normal; body naked or sometimes with bony 
lateral shields. HEMIBRANCHII 
gg. Gills tufted; skin covered with bony plates.
