 below. Pectoral with outer angle broadly rounded, hind edge con- 

 vex, and hind angle not extended.

 32, with hindmost farther apart. Two mounted examples, each about 

 4575 mm. long, from Moreton Bay, Queensland, seen in the Queens-

Head to last gill opening nearly 2i/2 in total length; width at 

 spiracles 3 in its length to spiracles. Snout l^e hi head measured 

 to spiracles; eye 17, 15 in snout, 3l^ in interorbital ; rostral teeth

 arched forward, 6 in preoral length, labial folds rudimentary; teeth 

 very small, 78 rows above, 76 below, in pavement; nostrils wide, 

 oblique, front valve with broad rounded median lobe, hind valve 

 narrowly free behind, with outer division extended as partition into 

 nostril in sort of flap below lobe of front valve, internarial greater 

 than nostril width and over half space to mouth; interorbital 514 

 in head to spiracles. Gill openings small, last smallest, outer edges
