Durino" 1901, Prof, J. B, Steere made collections for the United 

 States National Museum in the Amazon Rivei" l)etween Para and 

 Manaos. Amono* these collections were a number of fishes, nearly all 

 of mediiim size, which were selected of a certain length for exhibition 

 at the Pan-American Exposition held in Buffalo, New York, in 1901. 

 Most of them were displayed in formalin, and proved an interesting 

 addition to the exhi])it of fishes made by the Museum, 



The collection contains a number of interesting forms, several of 

 which are here described as new. We are indebted to Dr. Theodore 

 Gill for suggesting the name Ta'nionerna for the catfish with the 

 flattened (tape-like) barbels, named specifically in honor of Professor 

 Steere. 



A note on some specimens of Plutelodus eJarias from Paragua}" is 

 added to this paper. 



POTAMOTRYGON HUMBOLDTII (Roulin). 



One specimen. 



SELENASPIS HERZBERGII (Bloch). 



Three specimens, 185, 175, and 145 mm. long. These agree well 

 with Bleeker's figure of Ilexanematichthys Jiymenorhi7io.<t^ which is 

 evidently the 3"oung of Jterzbergii. 



CALLOPHYSUS MACROPTERUS ( Lichtenstein). 



Two specimens. 



PINIRAMPUS PIRINAMPU (Spix), 



One specimen.
