Tocantins (three specimens). Cope states that this species is 

 pecnliai- in the number of its abdomino-thoracic dentation, and 

 gives the number of serrations as 41. I find only 31 in two of 

 my specimens as Cope's figure shows. The third specimen is 

 somewhat more slender, the dark edges of the caudal and anal 

 fins are conspicuous, the longitudinal series of round black spots 

 above the lateral line not evident and there are 36 abdominal ser- 

 rations.
