Genus cristivomer Gill & Jordan 



This genus contains one or two species, large, coarse chars, 

 distinguished from Salvelinus by the presence of a raised 

 crest behind the head of the vomer and free from the shaft; this 

 crest is armed with teeth. The hyoid teeth constitute a strong, 

 cardiform band. The typical species is a large char or trout, 

 spotted with gray instead of red, and found in the larger lakes 

 of eastern North America. (After Jordan and Evermann) 



The species namaycush is found also in a lake (Henry) 

 in Idaho, in the Columbia river basin, and northwestward to 

 northern Alaska.
