Amazonian Fauna. — When we enter that vast territory lying east of 

 the Andean system, we leave behind us the more distinctive features of the 

 Colombian fauna. We stand now, as it were, on the shores of a great ocean 

 of life which stretches far beyond the boundaries of Colombia. No adequate 

 analysis of its affinities can be based on the study of a restricted part of it. 

 The problem is as wide as the combined Amazonian and Orinocan basins. 

 It should, therefore, be understood that in applying the term Amazonian 

 Fauna to that portion of tropical Colombia included in the Amazonian 

 drainage system, it is not intended to imply that we have here a definite 

 faunal area, but that the faunal affinities of this southeastern section of the 

 republic are with that wide-spreading region to which the name Amazonia 

 is commonly, if somewhat vaguely, applied.
