bulletin of the bureau of fisheries. 
The tullibee or tulipi is the most abundant fish in the lakes tributary to Lake Winnipeg, its young 
forming a large part of the food of the wall-eyed pike or yellow pike, Stizostedion vitreum. It is not 
highly valued as food, its flesh being rather watery and tasteless. In the summer it is largely infested 
with worms, which are found in the flesh of the back. In winter it is more esteemed. 
The southern distribution of the tullibee is unknown. It occurs in certain small lakes of Minne- 
sota and is reported in those of Wisconsin. Eastward Leucichthys artedi bisselli and Leucichthys erien- 
sis, species not at all related, have been confounded with it. Doctor Bean records it from Onondaga 
Lake, in New York. We have seen no specimens of the true tullibee from the Great Lakes, but we 
are told that it occurs in Lake Superior and the North Channel of Lake Huron. Doubtless these 
statements refer to L. manitoulinus. The “mongrel whitefish” of Lake Erie, once supposed by the 
present writers to be the true tullibee, proves to be Leucichthys eriensis.
