Forbes (1909, p. 123) examined 22 specimens. 25 per 
cent. of the food consisted of algze and miscellaneous vege- 
table debris: ‘ Four of these specimens had eaten little else 
than filamentous alge, and three had captured small fishes. 
Grasshoppers, caterpillars, ants, chrysomelid and scarabaeid 
beetles and various other terrestrial insects, together with 
Corisa, dipterous larvee, and other aquatic forms, were the 
insects represented, and three of our 22 specimens had eaten 
only crawfishes.” The food of this species is not recorded by 
Hankinson. 
C. REFERENCES IN LITERATURE TO FOOD OF 
NEW YORK FISHES. 
Several investigators working on aquatic problems in New 
York State, mention the presence of mollusks in the stomach 
contents of fish. These are noted below: 
Lepomis megalotis (Rafinesque). Long-Hared Sunfish. 
Needham (1901, p. 402) examined one specimen of this 
sunfish collected at Saranac Inn, Adirondacks, the molluscan 
content being upwards of 65 per cent. The data appears 
below. The higher percentage of mollusks is noteworthy, 
Forbes (1880, a, p. 53) finding but 16 per cent. in Illinois 
fishes. 
34 Physa heterostropha and Lymnaea (Galba) desidiosa, the largest 
being 1.5 mill. long. 
12 Larve of gnats (chironomids). 
1 Larve of Chauliodes, in fragments. 
Eupomotis gibbosus (Linnaeus). Puwmpkinseed. 
Needham (1908, a, p. 176) examined 25 sunfish, taken 
in a weed patch near the hatchery wharf at Old Forge pond, 
Adirondacks, July 10, 1915. Dividing these into three lots,
