by Johs. Schmidt. 
The following list of marine Peridiniales is due to the exami- 
nation of a number of plankton samples collected by the Danish 
Expedition in the inner part of the Gulf of Siam. The samples 
which are 10 in number, were obtained from the surface of the Sea 
by means of fine silk-nets and were preserved in formaline (4 °/o)').
