DIATOMS OF NEW BRUNSWICK.

III. — Forms From The North Shore. 
In a previous Bulletin of this Society (Vol. VI, Part II), an 
account is given of the Marine and Estuarine Diatoms of the 
south coast of New Brunswick, including lists of species obtained 
in Passamaquoddy Bay and adjacent waters, about St. John 
and the lower portion of the St. John River, and at St. Martins. 
In the present paper it is proposed to give lists of those since 
observed on the north shore of the Province fronting the Gulf 
of St. Lawrence. The localities from which the collections 
were made include Shediac, Cocagne, Richibucto, Chatham, 
Newcastle, Bathurst, Campbellton, and Dalhousie, as well as 
intermediate points, but in most cases near the shore, little 
opportunity having been available for dredging at more distant 
points or for the making of plankton gatherings. 
Compared with the south or Bay of Fundy shore of the 
Province, that of the “ North Shore” presents in many particulars 
important contrasts. Thus, while along the whole length of 
the former the coast is rocky, often bordered by precipitous 
bluffs and with waters of considerable depth quite up to their 
base, and with numerous rocky islands fringed with sea weed, 
the northern shores are almost everywhere low, and the adjacent 
waters very shallow, even for long distances from the coast- 
line. About the Bay of Fundy tidal action is powerful, and 
the change of tidal level from twenty-five to thirty feet; that 
of the Gulf Shore is feeble, and the change does not exceed five 
or six feet. The waters of the Bay, and even in the lower part 
of the St. John River, constantly stirred by tidal movements, 
are very cold; those of the north shore are much warmer and
