large and the fish had eaten almost entirely of this one 
species. The Tullibee, judging by the contents of this 
stomach, takes its food from near the surface, at least at 
some seasons. Determined by Dr. C. D. Marsh.

Cyclops, species not identified, were noted in the stomachs

form, and the fish from which it was taken was collected by 
Dr. C. C. Adams, on October 12, 1915, in shallow water.
