Orinoco, Maranon, to Rio Paraguay 
—, 3, 102-153 mm., Iquitos, Allen, August, 1920. 
Separated by Fowler from the remaining Leporinus species on the longer basis 
of the anal fin. Borodin points out the additional characters: weak attachment 
of the gillmembranes; very deep and hump-backed body, which he regards as a 
step in the direction of the Tetragonopterines. He accepts Abramites logically 
as a probable future subgenus. 
On the Marafion above Iquitos I encountered a young man who took from his 
pocket and showed me a mummified specimen of hypselonotus, known to him under 
the name San Pedro, which he informed me was his “‘lucky piece.’’ The good 
fortune it was supposed to bring was not at all evident about his person. 
All of Mr. Bartlett’s specimens were found by Giinther to have the gill-chamber 
of one side occupied by parasitic Crustacea.
