more than 100 rotifers which belonged to the species of 

 Eydatina. In all, about one hundred of these small fish 

 were studied from various stations in the lake and all 

 were found to be eating the same food, with but a small 

 amount of individual variation. The same is equally true 

 of the adults of this species. 



Ameiurus nebulosus Le Sueur. Common Bullhead.— 

 The bullheads in Lake Clear vary their diet, as plant re- 

 mains, crayfish, clams, snails, plumatella and daphnia are 

 all found. 



Catastomus commersonii Lacepede. Common Sucker. 

 —Plant remains, crustacean skeletons, sand, plumatella 

 and debris are all found. 



Notropis cornutus Mitehill. Shiner.— Daphnia and in- 

 sects constitute their diet. A number were found with 

 honey bees in the stomach. 



Leuciscus carletoni Kendall. Black-striped Minnow.— 

 Insect larvae, rotifers, alga?, plumatella and daphnia were 

 all found. 



In view of the importance of the whitefish as food fish 

 the details of this study are given. 



Coregonus clupeiformia Mitchell. Common Whitefish ; 

 Labrador Whitefish.— These whitefish are by all means 

 the most numerous fish in the lake, as from three to four 

 thousand are taken in the fall nets at once. More white- 

 fish are caught than all of the other species combined, so 

 far as my observations go. One would naturally expect, 

 then, that mow of (load whitefish would be found along 

 the shore than of any other species. If one happened to 

 make his observations just when the whitefish are dying, 

 the above would be correct; but not more than two or 

 three times during a summer are any considerable num- 

 ber of whitefish to be found dead upon the shores. The 

 following notes illustrate this point. 



Dead whitefish collected between September 19 and 24, 

 1916, just as they drifted onto the north shore between 

 the small brooks stations 1 and 2, and the East Flats, give 

 the daily record as follows: September 19, two males,
