not have given us the information needed to map its zones and faunas with 

 a thoroughness which would begin to express all the facts and factors in- 

 volved. 



We must, therefore, leave to future workers the task of filling in the details 

 of our work in Colombia, with a hope that they will find the zonal and f aunal 

 boundaries here proposed at least fundamentally correct. 



ACKNOWLEDGMENTS. 



The American Museum gratefully acknowledges the courtesies extended 

 to it by the Colombian Government through its representatives in this 

 country, and its administrators at the ports of Barranquilla, Buenaventura, 

 and Tumaco. The consideration shown us by these gentlemen, and the 

 promptness with which our equipment and supplies have been admitted to 

 their country has materially advanced the objects of our expeditions. 



To the representatives of our own country in Colombia we are also 

 indebted for many courtesies. 



We have received so many favors from individuals that properly to 

 acknowledge them would require the enumeration of the names of the scores 

 of persons on whom, for one purpose or another, we have called for assistance. 

 Our requirements were often so unusual, or, to us, so pressing, that to meet 

 them was frequently not a matter of their money value, and we had then to 

 rely upon the generosity and good-will of those on whom we were in truth 

 dependent. In this connection we are particularly under obligation to 

 Mr. Chas. J. Eder, of the beautiful sugar estate La Manuelita, near Palmira 

 in the Cauca Valley. After entertaining our first expedition at his home, 

 Mr. Eder not only placed his bungalow 'Miraflores,' in the mountains, 

 and ranch 'Guengiie' at our disposal, but supplied us with mules to make 

 the journey from one to the other. We. have also to thank Mr. Eder for 

 many personal attentions which added materially to our comfort, and for 

 letters to his agents in various parts of Colombia. 



Mr. Henry Eder, of the firm Eder & Co., at Call, acted as our forwarding 

 agent during the year or more of our work in the Cauca region and through 

 his efficient service we completed our labors without the loss in transporta- 

 tion of a single specimen or item of equipment. 



In Bogota, Mr. F. L. Rockwood has acted in a similar capacity for cer- 

 tain small collections acquired since our expedition left that region. For 

 these we have mainly to thank Hermano Apolinar Maria, Director of the 

 admirably arranged museum of the Instituto de la Salle.
