Fundulus diaphanus (LeSueur). Fresh Water Killy. 
Hankinson (1908, p. 209) found the food of this fish to 
consist of midge larvae, water-fleas, may-fly larvee, beetles, and 
a small amount of filamentous algw. Forbes (1883, a, p. 71) 
found the western variety menona to feed upon a variety of 
material, as noted: 
Vegetable matter, largely seeds................ 20 per cent. 
Insecta (Chironomus, Hydrophilide, Ephemeride 
larve, terrestrial insects and spiders)........ 40 per cent. 
Crustacea (chiefly Allorchestes dentata)....... 20 per cent. 
Molbisean (Planorbis), 5. 20s 21.Joe Be Ss eS 5 per cent. 
WSAGMATICO US: 8) hh nthe Ws) ie cats aia = Bee 15 per cent. 
Planorbis, taken in June and October and Pisidium taken 
in June were noted. 
7+ Fundulus dispar (Agassiz). Killifish. 
Kighty per cent. of the food (Forbes, 1883, a, p. 73) of 
this species consists of animal matter, of which 25 per cent. 
is molluscan. Insects form another 40 per cent. and crus- 
taeans only 4 per cent. ‘Three molluscan genera, Physa, 
Planorbis (taken in July) and Valvata sincera (probably 
should be lewisiz) were noted. 
1 Fundulus notatus (Rafinesque). Top Minnow. 
Insects form the chief diet of this fish. Entomostraca and 
other Crustacea are also present, as well as about 3 per cent.
