Great Lakes containing most of them. They are 

 classified as follows : 



The Richardson whitefish {Coregonus richardsonli) 

 is considered a doubtful species, being probably- 

 identical with other species of the Arctic region, 

 where it is found. The present name and classifi- 

 cation of this fish is only provisional. 



The pilot-fish, menominee whitefish, shad- 

 waiter, and round whitefish [Coregonus quadrilatera-

 of New England and the Great Lakes. It may be 

 recognized by its long head, compressed and bluntly 

 pointed snout, small adipose fin, and by the dark 

 bluish color of the body above the lateral line and 

 the silvery hue below. It is very abundant in its na-

The common whitefish {Coregonus clupeiformis , 

 the specific name from the Latin clupea^ " a shad 

 or herring " ) is found in the Great Lakes and 

 neighboring waters, and very rarely ascends streams. 

 It may be distinguished from its congeners by its 

 elevated body, comparatively small head, and blunt

 lower fins, olivaceous coloration above the lateral 

 line, and white, but not silvery, color below. This
