ABSTRACT 



Eight species of freshwater polychaetes are re- 

 ported in the form of a key. Three families are 

 represented: Nereidae with six species; 

 Sabellidae with one species; Serpulidae with one 

 species. The key includes only those polychaetes 

 actually collected from freshwater and not those 

 reported to withstand low salinities under ex- 

 perimental laboratory situations. Collection 

 and preservation methods are discussed as well as 

 characters used in specific identification.
