Hab. Lake Erie and the Upper Lakes. 
Observations. A few specimens are occasionally 
taken at Cleveland and at other places on the shores 
of Lake Erie, but they are most abundant and attain 
the greatest size and perfection in some of the Upper 
Lakes, where the business of taking and preserving 
them gives employment to many persons during cer- 
tain seasons of the year. They are esteemed as the 
most valuable of the western fishes. They are dis- 
tinguished from the Coregonus Artedi by their great- 
er size, their color, and the flattened form of their 
bodies. 
The stomach is small, with thick mucous and mus- 
cular coats; the length of the intestinal canal, in- 
cluding the esophagus, stomach, and intestines, does 
not exceed the total length of the fish. One half of 
the contents of the abdomen seems to consist of NU 
merous ceca. I have never, been able to detect 
substance within their stomachs except a quantity 
decayed wood, thickened mucus, and the apparently 
comminuted seeds of a polygonum. The stomachs 
of the C. Artedi usually contain numerous small 
fishes. The jaws of the white-fish are edentulate-
