800 A JOURNEY IN BRAZIL. 
Lieutenant-Colonel of the National Guard of Mauhes, re- 
turning to his home there, after a stay of several weeks 
in Manaos. Besides these, our party consists of Major 
Coutinho, Mr. Burkhardt, and ourselves. The position of 
Mauhes, on the southern side of the Amazons, and its 
proximity to Manaos and Serpa, may make this excursion 
especially instructive, with reference to the study of the 
geographical distribution of the Fishes in the great net- 
work of rivers connecting the Rio Madeira and the Rio 
Tapajoz with the Amazons.
