Specimens were placed in 95 per cent alcohol as soon as they 
were collected, the larger individuals being slit along the abdomen. 
They were then taken to the laboratory and sorted. In making 
examinations the entire alimentary canal was removed, placed 
on a slide, and its contents carefully forced out with a pair of 
needles. Examination was then made with both dissecting and 
compound microscopes. An estimate by volume of the percent- 
age of each article of food was then made and recorded. All 
figures used in this paper refer to such volumetric percentages.
