Candal fin rounded ; the soft dorsal and anal fins rather elevated ;

Atlantic coasts of America from New York to the coast of Su- 

 rinam ; Caribbean Sea. Ceylon ; Bay of Bengal ; Sunda, Molucca, 

 and Chinese Seas. 



As in all fishes which attain to a considerable size, the individuals 

 of this species are subjected to some modifications of several external 

 characters ; for instance, of the denticulations of the prseoperculum, 

 of the colours, and of the height of the fins. I cannot find any 

 determinable difference between specimens from the old and new 

 world. Lobotes ineurvus is founded on a half-grown specimen, with 

 the vertical fins scarcely longer than usual.
