SERIOLA ZONATA. 73 



of the abdominal cavity ; its apex is behind and pointed, its basis is before and has a minute horn on 

 each side, directed forwards and outwards ; these horns are so small as to resemble, at first sight, 

 ligamentous bands ; yet examination shows them to be pervious. 



Habits. The Seriola CaroUnensis lives in deep water, and is taken along the 

 coast of South Carolina at all seasons of the year, but is never abundant. , 



Geographical Distribution. As yet, this fish has only been observed in the

General Remarks. At first, I supposed the Jack-fish might be the Seriola 

 Boscii of Cuvier and Valenciennes ; but it does not agree with their description, 

 in many particulars, as in its colour, in the number of its dorsal fin rays, or 

 in size.
