No attempt has been made to give a complete reference of 
species, but to give references preferably to such works as are 
generally easiest of access. It will be noticed that most of them 
are referred either to Schmidt’s Diatom Atlas, or to Van Heurck’s 
synopsis. The references in roman mention Santa Monica as the 
locality. The references in italic indicate other localities.
