PLATYHELMINTHES 



Since no member of the Survey staff had special knowledge 

 of this group, the following list represents only a few con- 

 spicuous forms, chiefly from fresh water, which could be deter- 

 mined with certainty from the literature at hand without 

 making a special study of the group. The North American 

 free-living members of this group have been best treated in 

 two papers. Stringer (1918) and von Graff (1911). We may 

 also refer to the series on the Turbellaria by L. H, Hyman 

 (1931, etc.) and another by Kepner and his students, both 

 in course of publication. 



As to the parasitic forms, it will suffice to call attention to 

 Manter's (1925) report on some species from the Mount 

 Desert Eegion.
