denticles on the outer edge between the notch and the base. Orbit longer than 

 wide, nictitating fold well developed. A small spiracle behind the eye. First 

 dorsal above the space between pectorals and ventrals; second dorsal above the 

 anal. Caudal rather short; subcaudal lobe, not very distant from the notch 

 behind the subcaudal; caudal pits absent. Hindmost gill clefts above the 

 pectorals. Species from Lower Tertiary closely resemble living forms. 



Second dorsal and anal fins subequal 



snout produced, anterior nasal valve with two points . galeus (page 153) 

 Second dorsal much larger than the anal 



snout rather short, anterior nasal valve with a rounded lobe
