The measurements are without the caudal filament, which in many 

 cases is longer than the rest of the fish. 



The specimens from Santarem are small and evidently immature. 

 The teeth are as those from Para, in which they are typical of the 

 species. The back and sides are thickly covered with brown spots, 

 which is unusual for this species. The dorsal has a black spot near 

 its middle about the size of the eye. The caudal filament, though 

 short, is present in one of the specimens, the caudal of the other being 

 broken.
