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 vicinity. 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.
