IX. ON VARIOUS SOUTH AMERICAN PCECILIID FISHES. 



By Arthur W. Henn.^ 

 (Plates XVIII-XXI.) 



Introductory. 



The present account is largely based upon collections made from 

 1907 until 1910, by Mr. John D. Haseman in central South America, 

 during the expedition of the Carnegie Museum. An account of this 

 expedition with a list of the localities, where Mr. Haseman made 

 collections, was published in these Annals, Volume VII, pp. 288-314. 

 A review of the specimens obtained by Professor C. H. Eigenmann 

 during a reconnaissance of the basins of the Magdalena, Cauca, Dagua, 

 San Juan, and Atrato Rivers of Colombia is included. This expedi- 

 tion was under the auspices of the Indiana University and the Carnegie 

 Museum. 



Besides this material I have examined and included a list of the 

 specimens obtained in 1913, by Mr. Charles E. Wilson when on the 

 Landon-Fisher Expedition of Indiana University to western Colombia, 

 and those secured by the writer in southwestern Colombia and 

 Ecuador in 1913 and 1914 during the Landon Expedition of Indiana 

 University. A review of the last three expeditions appeared in 

 Science for 191 4, pp. 602-606. 



The numbers, unless otherwise stated, are the catalog numbers of 

 the Carnegie Museum and the Indiana University. A full series of 

 the fishes obtained by the Indiana University Expeditions is included 

 in the collections of the Carnegie Museum. I have had constantly 

 at hand for reference the collections in the Museum of Indiana Uni- 

 versity, where this paper was prepared. 



For the species mentioned I have given in most cases the synonymy 

 and bibliography subsequent to the publication of Carman's mono- 

 graph of this family: " The Cyprinodonts," Mem. Mus. Comp. Zocil., 

 V'ol. XIX, No. I, 1895. In a few cases, where the synonymy in 

 that work was inaccurate or obscure, I have given the complete 

 synonymy since the earliest reference to the species.
