Birge—Notes on Gladocera. 
Washington Harbor, Isle Roy ale, was carefully examined. 
There was a very scanty pelagic fauna. This was true of all 
places where I dredged on the north shore of Lake Superior. In 
the shallows at the head of the harbor were found Drepanothrix 
dentata in large numbers (not previously found except at 
Madison), Alona falcata , Chydorus rugidosus , Pleuroxus nanus. 
In the following table l denotes that the species was found in 
the littoral waters; p, that it is pelagic; m, that it was found 
in marshy waters.
