elements of the plankton are the chief source of food in nature is still 

 to be determined. When this question has been settled, it will probably 

 be possible to grow the required food organisms in the laboratory and to 

 keep Calanus and other copepods in culture indefinitely. (See addenda 



on p. 571.)

TIGRIOPUS FULVUS 



THIS harpacticid copepod is very large for the group. It has been 

 reported from the Mediterranean, the coast of California, and else- 

 where in warm climates. In suitable localities it is found, often in 

 incredible numbers, in spray-pools above high tide mark. It may be
