Abstract 



Eight species of freshwater polychaetes are reported 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 experimental 

 laboratory situations. Collection and preservation methods are dis- 

 cussed as well as characters used in specific identification.
