There is in Sao Paulo in the rivers of the Rio Parana system, 

 especially in the system of the Rio Tieti, only one other fish which 

 attains the dimensions of the Jahu ; this is the Pseudoplatystoma 

 coruscans Ag., called Piracampacii. I got both at Piracicaba. The 

 genus Paulicea is identical with the nameless genus No. XXXII, of 

 C. H. and R. Eigenmaun, 1 a genus which contains besides the new 

 species here described, one Amazonian species P. lutkeni Steind., 

 described as Platystoma.
