As a whole the food of the genus Fundulus may be sum- 
marized as follows (Forbes, 1883, a, p. 73):

{ Gambusia affins (Baird and Girard). Viviparus Top- 
Minnow. 
Three genera of mollusks have been taken from the stomach 
of this top-minnow. (Forbes, 1888, b, pp. 512-513.) 
Valvata sincera (probably should be lewisii?) taken in September. 
Physa, taken in September and October. 
Planorbis, taken in September. 
Labidesthes sicculus (Cope). Brook Silversides. 
Forbes (18838, a, p. 65) examined 25 specimens of the 
Brook Silversides, finding the food to be purely animal, a 
little over half consisting of insects and a little less than half 
crustaceans. The larvee of Chironomus were among the im- 
portant elements, making 30 per cent. of the whole. The 
crustaceans were all Entomostraca, including Copepods and 
Cladocera; Daphnia, Simocephalus, Bosmina, Chydorus, 
Pleuroxus, Alona, and Hurycercus occurred among the 
Cladocera, and Cyclops, Canthocamptus, Diaptomus, Iimno- 
calanus and EH pischura among the Copepods. A few terres- 
trial insects, accidentally washed into the water, formed about 
12 per cent. of the food. According to Forbes (1888, a, p. 
513) unrecognizable Mollusca have been found in the stomach 
of this fish. Four specimens from Oneida Lake were exam- 
ined and the stomach contents noted. They were collected 
in the west side of Ladd Bay, near Ladd Point, on a sand 
bottom, covered with Bulrushes, September 3, 1915. 
No.1 (101) 53 mill. long. 
Insecta. 23 adult midges, fragments* . ae 80 per cent. 
*Midges were noted by counting the number of pairs of eyes, all flies 
being represented only by fr agments.
