In distribution this species begins where A. aeneus leaves off. It is found 

 from the Balsas and Papaloapam north to Texas. It is more slender than 

 A. aeneus and has fewer anal rays, but does not materially differ in other respects. 



Usually 4 teeth in the outer series of the premaxillary, 1 to 3 teeth in the 

 maxillary. 



For the details of the anal see page 297. 



First few anal rays without pigment, the first two milk-white toward their 

 tips.
