492 AMERICAN FISHES. 
held in higher esteem than any other fish. Being a soft fish, it spoils 
rapidly, and in the condition in which it usually reaches the consumer its 
edible qualities have greatly deteriorated.” 
This summary of the habits of the common Whitefish will apply in the 
main to the other species of the genus. The others differ chiefly in the 
size to which they attain, the waters they frequent, and the temperature 
they prefer. 
Another Whitefish having as extensive a range as the common species is 
the Round Whitefish (Coregonus guadrilateralis) called also Menominee 
Whitefish, Frost-fish, Pilot-fish, Blue-back, Shadwaiter, etc. It sometimes 
reaches a weight of two pounds, but the average weight of those brought to 
market is somewhat less than a pound. 
LABRADOR WHITEFISH. 
A larger species than the Round Whitefish, but smaller than the com- 
mon, is that inaptly named Labrador Whitefish (Coregonus labradoricus), — 
inaptly, because it also is a wide-ranging form, although it prefers colder 
waters than the two preceding, being most abundant in the cold northern 
lakes of the Canadian Dominion and in Lake Superior. By the “ voya- 
geurs” and hunters of the old Hudson Bay territory it was very highly 
regarded and was known to them chiefly as the Attihawmeg. It was con- 
sidered to be “the most delicious of all purely fresh-water fishes.” Its 
usual weight is from two to three pounds, but one has been recorded of the 
weight of thirteen. Among the other names may be mentioned Shad, 
Shadwaiter, Gizzard-fish, and Whiting.
