200 SUMMAKY OF CUREENT RESEARCHES RELATING TO 



time from the British Isles ; a new genus of Protococcoidefe is described, 

 and other interesting species are mentioned as occurring in the col- 

 lections. General remarks are made on Scottish phytoplankton, and a 

 summary of our present knowledge of the phytoplankton of the inland 

 waters of the West of Scotland completes the paper. Five plates of 

 microphotographs and two of ordinary figures add largely to the value 

 of this paper.
