lY. Conclusions. 



Although our knowledge of Western Colombia is still very far 

 from complete, yet the reseaiches of the natui'alists mentioned 

 in the first part furnish sufficient evidence on which to base 

 some conclusions as to the general character and affinities of the 

 avifniina of this remote district. As might be expected from its 

 geographical situation, the fauna of Western Colombia shows a 

 mixed character, being composed partly of Ecuadorian and partly of 

 Central American species, the former, however, by far preponder- 

 a,ting. The most interesting result derived from Mr. Palmer's 

 collection is evidence of close similarity of the avifauna of the Snn 

 Juan Valley to that of the province of Esmeraldas, N.W. Ecuador. 

 In fact quite a number of remarkable species are apparently peculiar 

 to S.W, Colombia and the adjoining parts of N. Ecuador, while in 

 the more southern districts of Western Ecuador other moi-e or 

 less allied forms take their place. In several instances, however, 

 the Choco region has a species or subspecies of its own, while 

 the province of Esmeraldas is inhabited by a representative form 

 generally distributed over Westei-n Ecuador. 



A few species range from Panama to N.W. Ecuador, but do 

 not go further south. Several others extend from Panama to the 

 Dagua district, whereas in N.W. Ecuador another species or race 

 is found. 



The subjoined tabular lists t may serve to illustrate these facts, 

 which are of some importance to the student of zoogeographical 

 problems.
