All photographs in the field were made by the author during July, 

 19 16. In some of the quantitative figures, which are intended to show 

 the general character of the fish food, it has not been possible to include 

 all of the specimens on a 5 x 7 plate and a few individuals have been 

 eft out or only partly included. In these cases the total number of 

 ndividuals of the unit area are not shown on the plate.
