distribution of Colombian frogs by political subdivisions, for the list- 

 ings emphasize the areas where both extensive collecting and intensive 

 collecting are needed. 



Following is a list of the 25 principal political subdivisions in 

 Colombia sequentially arranged according to the decreasing number of 

 known species and subspecies of frogs. 



We feel that in only a few areas has collecting been thorough enough 

 to provide representatives of all species that actually occur in these 

 political subdivisions. The single species known from San Andres y 

 Providencia probably is the only one that occurs there, but it would 

 be ridiculous to assume that no frogs are to be found in Arauca and 

 that only two species inhabit Vichada. It is certain that Colombia will 

 remain a fertile field for avid collectors for many years to come. 



Following is an alphabetically arranged listing of the principal 

 subdivisions with the names of the species and subspecies known 

 from each.
