DIATOMS OF NEW BRUNSWICK. 
399 
Diatoms from Coast Between Bay Chaleur and Bathurst. 
This coast is also bordered by Silurian and Devonian rocks 
(calcareous limestones and intrusives) usually forming low 
bluffs and islands; but these are crossed by many streams, the 
shallow mouths of which, more or less occupied by eel grass, 
afford favorable opportunities for diatom collecting. The 
stream-outlets examined include Jacquet River, Benjamin 
River and Tattagouche River, while some collections were also 
made at intermediate points.
