The common whitefish of the Great lakes is so well known 

 that it scarcely needs an elaborate description. The body is 

 stout and deep, its depth at the nape greatly increased in adults. 

 The greatest depth is two sevenths of the total length to caudal 

 base. Caudal peduncle short, its depth one half the length of 

 head, which is about one fifth of total without caudal. The 

 snout is sharp, conical, two sevenths as long as the head and 

 about twice as long as the eye. The maxilla reaches to below 

 front of eye. The dorsal origin is above the 23d scale of the 

 lateral line, and the ventral begins under the middle of the 

 dorsal. The longest dorsal ray equals length of head without 

 snout, adipose fin stout and low. The dorsal and anal bases
