Introduction. 
The land flora of New Brunswick has been the subject of 
study by many observers, and a fairly complete though not 
exhaustive list of the terrestrial plants of the Province has been 
made. But there is one group of low but very beautiful forms 
to which almost no attention has been paid. This is the group 
of the Diatoms, a family of microscopic Algae of the Class 
Chlorophyceae, abounding everywhere, but, owing to their 
minuteness, beyond the reach of ordinary observation. A list 
of those occurring at Harris’s (or Matthew’s) Cove, on the 
Kennebecasis, was published by the writer in the Bulletin of the 
Natural History Society for 1863, and subseqently short lists of 
forms observed about Chatham were published in the Proceed- 
ings of the Miramichi Natural History Society, by Dr. J. McG. 
Baxter, but, with these exceptions, there is absolutely no 
reference to these interesting forms in the botanical literature 
of the Province. 
It having been the writer’s good fortune to spend several 
weeks in the summer of 1909, at the Biological Station at St. 
Andrews, and a considerably longer period in 1910, his interest 
in the study of the Diatoms was, after nearly fifty years neglect, 
renewed, and the opportunities afforded for their more careful 
study were eagerly embraced. These opportunities included not 
only the examination of collections made by members of the 
staff in the immediate vicinity of the Station, including the
