A SECOND LIST OF ALGAE FOUND IN WISCONSIN 
LAKES 
Gilbert Morgan Smith 
Notes from the laboratory of the Wisconsin Geological and 
Natural History Survey XIV. 
The following list of algae is a continuation of the study of 
Wisconsin algae under the auspices of the Wisconsin Geological 
and Natural History Survey. The collections of the past sea¬ 
son (1916) are from two lake areas that were not visited before; 
the Southeastern part of the state in Walworth, Kenosha and 
Kacine counties, and the Northwestern in Sawyer, Washburn, 
Barron, Rusk and Polk counties. The scope of the work has 
been curtailed since the publication of the first list and atten¬ 
tion has been confined to the phytoplankton. 
Following the system used in the preliminary list, the exact 
location of each new lake is given in the following table. 
In citing the geographical distribution of the lakes they are 
placed in three groups as follows: I, those mentioned in the pre¬ 
liminary list; II, the Southeastern lake area; III, the North¬ 
western lake area. In order to show the relative abundance of 
each individual species the following symbols are used; (aaa) 
very abundant, (aa) abundant, (a) fairly abundant, (ccc) very 
common, (cc) common, (c) fairly common, (s) fairly scarce, 
(ss) scarce, (sss) very scarce, (r) fairly rare, (rr) rare, (rrr) 
very rare.
