LuMiNA C. Riddle. 



During a six weeks stay at the Lake Laboratory the writer 

 kept a careful list of all the algae found in water from Sandusky 

 Bay and vicinit^^ Those not found in the Bay have the name of 

 the locality following that of the plant. Those names not 

 included in Dr. Kellerman's preliminary check lis of Ohio Algae, 

 in The Naturalist nor in " The Plants of Western Lake Erie" 

 by A. J. Pieters are marked by the letter n. The nomenclature 

 is that used in De Toni-Sylloge Algarum.
