Generic Characters. — Jaws undivided, forming a cutting edge ; body com- 

 pressed, deep for its length, short, truncated, without spines ; tail short, and 

 very high vertically ; rays of the dorsal and anal fins long and pointed, both 

 united to the caudal fin at the base. 



The Sun-fish, as this species has been called from the 

 twofold circumstance of its almost circular form and shining 

 surface, though occurring but occasionally, may be said to 

 have been taken from John o'G]'oat"'s to the Land's End.
