 Spiracles large, deep, twice eye, edge fringed all around. 



Skin smooth. 



Dorsal 214 to 3 in head; second dorsal 2l^ to 2%; caudal 2% to 

 3%, rounded; pectoral convex, not very broad, forms deeply ovate

Queensland, New South Wales, South Australia, West Australia. 

 One from Moreton Bay seen in the Queensland Museum. 



Waite says, "I unwittingly placed my hand on one as it lay on 

 deck partly concealed by overlying fishes. As was afterwards found, 

 it was the largest example obtained, and measured 690 mm. (2 feet 

 3 inches) in length. The shock I so unexpectedly received was very 

 intense and it is quite conceivable that one from such a fish, not 

 previously harassed, would be sufficient to disable a man."
