Number of species, 65 ; number peculiar, 42 ; on Atlantic slope, 18 

 of which in Amazon, 3. 



These are for the most part lowland species belonging to lowland genera, 

 /. e., not such as are found in mountain streams or that are likely to have 

 reached the Pacific slope by crossing the high Andes. Pygidinm and 

 Chcetostomus are exceptions to this. If all of the purely freshwater species 

 could be transferred to Manaos or Tabatinga there are very few that would 

 occasion surprise if taken in the collector's net.
