SESSIONAL PAPER No. 38a 
NOTES ON THE PHYTO-PLANKTON OF THE BAY OF FUNDY AND 
PASSAMAQUODDY BAY. 
By L. W. Battey, M.A., Ph.D., LL.D., F.R.S.C., Emeritus Professor of Natural 
History in the University of New Brunswick, Fredericton, N.B. 
In previous publications relating to the Diatoms of New Brunswick and Prince 
Edward Island, fairly complete lists of these, as found at a series of localities along 
the Atlantic coast, have been given, but no attempt has been made to distinguish 
between littoral or neritic and deeper water or planktonic forms, or to show the rela- 
tions of either of these to differences of season and environment. Yet it is obvious 
that, as with other plants, such varying relationships do exist, and as their varying 
abundance must directly affect the food supply of the different animals, such as young 
fishes, oysters, etc., which feed upon them, as complete a knowledge as possible upon 
these points is highly desirable. 
The present notes are intended mainly to apply to the Phyto-Plankton of the bay 
ot Fundy and Passamaquoddy bay, though occasional references are made to points 
on the north shore of New Brunswick and to Prince Edward Island. Moreover, as 
the line between planktonic and non-planktonic forms is ill-defined, species ordinarily 
regarded as neritic are not unfrequently met with far from shore, and may even con- 
stitute a considerable part of any planktonic gathering. In the following pages, lists 
of such gatherings from numerous localities are given for the various months of the 
vear, excepting December, for which latter month no data are yet available.
