J. J. MACKENZIE, B.A. 



Tlie following is a list of Algae which I collected and identified 

 during the summer of 1889, with the localities in which they were 

 found. I purpose continuing my observations, and will endeavour to 

 add to this list from time to time. 



The classification and nomenclature is that used in Wolle's " Fresh 

 Water Algae of the United States " and '*' Desmids of the United 

 States."
