Yalenciennes united the species mentioned by Agassiz 

 and Spix with the Tareira of Marcgrave, but separates 

 numerous other species from it on slight differences. 

 Steindachner, in his papers on the Fishes of the Magda- 

 lena and on the Fishes of Southeastern Brazil, has given 

 his reasons for uniting all these species with the tareira. 

 Bloch gives an easily recognizable figure of this species, 

 but represents it as coming from Tranquebar.

 ,035-. 46 m., from 61 different localities: Para; Gurupa;
