FRESHWATER ALGAE. 



THE following list was originally entrusted to Mr. S. M. Wellwood, but 

 unfortunately he was obliged to resign his position owing to continued ill- 

 health ; he has, however, with great kindness favoured me with a full list of 

 his discoveries which are included under his name. On his resignation, Mr. 

 J. M. B. Taylor and Mr. J. Paterson undertook the labours of compiling and 

 collecting, and I have myself with their assistance, and that of Mr. J. A. 

 Terras, collected and prepared the records from every source known to me. 

 "We have had the inestimable advantage of the assistance of Messrs. W. & G. 

 S. West. They have undertaken and completed the enormous labour of 

 verifying the large collections made by the late Professor Kennedy (now 

 at the Glasgow and West of Scotland Technical College). They have also 

 most kindly inspected and named a very large number of fresh specimens 

 sent to them from time to time. A sign ! means that the specimen so 

 marked has been verified by Messrs. West. With regard to all other 

 records, the responsibility for the occurrence of the species rests up<>n the 

 botanist whose initials follow after the locality.
