The Cauca-Magdalena Fauna. — The faunal area to which I woiild apply 

 the name Cauca-Magdalena embraces that part of the Tropical Zone which 

 is drained by the Cauca and Magdalena River systems from their source 

 northward to the arid coastal region, or Caribbean Fauna. 



It is divisible into arid and humid sections. The former embraces the 

 entire Cauca Valley and extends northward into Antioquia nearly to the 

 upper limits of navigation on the lower Cauca, and.also the upper Magda- 



1 In a future paper on the distribution of bird-life in Ecuador it is proposed to treat more fully of 

 the origin of the avifauna of the Tropical Zone of the Pacific Coast. In this connection I present only 

 some of the more striking instances of Tropical species common to both the Pacific Coast and eastern 

 Ecuador and Colombia, whose range appears to be separated by the Andes. 



' S. W. Ecuador, Magdalena Valley, and Amazonia, but unknown on Pacific-Colombian coast.
